Chapter 1. Introducing the RADIUS Server Service
RADIUS is a lightweight, datagram-based protocol formally specified in RFC 2865 that is supported by many devices and servers for external authentication. VPN concentrators, routers, switches, wireless access points, and many other devices have native RADIUS support. Such devices are known as RADIUS clients. Using the RADIUS protocol, they converse with RADIUS servers to authenticate entities, such as users attempting to access their resources.
1.1. The RADIUS Protocol
The RADIUS protocol itself is quite simple. There are four packet types:
Access-Requestpackets are sent from a client to a server to begin a new authentication conversation, or to respond to a previous response in an existing conversation and provide requested information.
Access-Acceptpackets are sent from a server to a client to indicate a successful authentication.
Access-Rejectpackets are sent from a server to a client to indicate a failed authentication.
Access-Challengepackets are sent from a server to a client to solicit more information from the entity being authenticated.
Each packet type defines:
A set of fields that must be included
Other fields that can be included to convey:
• Additional requirements • Information about the context of the conversation • Attributes of the entity after successful authentication
For example, an
packet should always contain user name and password fields. It can
contain other fields that provide information about the client making the
request, such as inclusion of the optional
field indicates that a packet is part of an authentication conversation
already in progress. Its absence indicates the start of a new conversation.
An authentication conversation always begins with an
Access-Request packet that does not have a
State field. If the RADIUS server only requires the user
name and password for authentication, then conversations will complete after
the server sends an
Access-Reject packet, depending on whether the
authentication credentials were valid.
If more information is required by the server, such as an SMS-relayed one-time
password sent to the user's phone, the additional requirement can be solicited
Access-Challenge response to the client, followed
Access-Request packet that has a
field that associates it with the existing conversation. The conversation
completes with an
Access-Reject packet depending on whether the one-time
password supplied in the second request matches the password sent to the
This conversational style in which the server accepts, rejects, or solicits more information makes RADIUS an excellent match for leveraging AM's authentication infrastructure. AM performs authentication using chains of authentication modules found in realms.
These modules identify authentication requirements that are conveyed to clients wishing to authenticate. The modules then accept values submitted by the user for verification. The mechanism for modules to convey these requirements to AM is through a finite set of constructs known as callbacks. By leveraging AM's flexible and extensible authentication mechanism, organizations can craft an authentication experience suitable for their needs, while using the same mechanisms for both HTTP and RADIUS authentication.
1.2. RADIUS Support
Two ForgeRock Access Management features support the RADIUS protocol: the RADIUS authentication module and the RADIUS Server service.
1.2.1. RADIUS Authentication Module
The RADIUS authentication module enables AM to act as a RADIUS client, delegating authentication to an external RADIUS server:
Use the RADIUS authentication module when you want AM to pass user names and passwords through to an external RADIUS server so that the RADIUS server can authenticate the users.
For information about configuring the RADIUS authentication module, see "RADIUS Authentication Module Properties" in the Authentication and Single Sign-On Guide.
1.2.2. RADIUS Server Service
The RADIUS Server service provides a RADIUS server within AM. The server authenticates RADIUS clients that are external to AM. The server is backed by AM's authentication chains and modules, thereby providing the possibility of multi-factor authentication in addition to simple user name and password authentication.
The following example shows the flow of a successful simple user name and password authentication attempt from a RADIUS client:
The following example shows the flow of a successful multi-factor authentication scenario in which the RADIUS Server service is backed by an authentication chain that includes the LDAP and the ForgeRock Authenticator (OATH) authentication modules. First, the LDAP authentication module requires the user to provide a user name and password. Then the ForgeRock Authenticator (OATH) module requires the user to enter a one-time password obtained from the authenticator app on a mobile phone:
The rest of this chapter covers the configuration of the RADIUS Server service in an AM deployment.
Chapter 2. Implementing the RADIUS Server Service
This chapter describes how to configure AM as a Remote Authentication Dial-In User Service (RADIUS) server that can accept authentication requests from RADIUS clients.
2.1. Configuring the RADIUS Server Service
The AM RADIUS server is disabled by default. To enable it, perform the following steps:
Login to the AM console as the top-level administrative user, such as
Navigate to Configure > Global Services, and then click RADIUS Server.
Under Secondary Configuration Instance, click New.
AM uses secondary configuration instances in the RADIUS Server service to encapsulate RADIUS clients. You must configure one secondary configuration instance, also known as a subconfiguration, for each client that will connect to the RADIUS Server.
Configure attributes for the subconfiguration. See "RADIUS Server" for information about configuring the subconfiguration attributes.
Click Add to add the configuration for the RADIUS client to the overall RADIUS Server service's configuration.
If you have multiple RADIUS clients that will connect to the AM RADIUS server, add a subconfiguration for each client. It is not necessary to configure all your RADIUS clients when you configure the RADIUS Server service initially—you can add and remove clients over time as you need them.
Configure global attributes of the RADIUS Server service. At a minimum, set the Enabled field to
YESto start the RADIUS server immediately after you save the RADIUS Server service configuration.
See "RADIUS Server" for information about configuring the RADIUS Server service's global attributes.
On the main configuration page for the RADIUS Server service, click Save.
The RADIUS server starts immediately after you save the configuration if the
Enabled field has the value
YES. Any time you make changes
to the RADIUS Server service configuration, they take effect as soon as you
save the changes.
Chapter 3. Troubleshooting the RADIUS Server Service
This chapter describes how to troubleshoot AM as a Remote Authentication Dial-In User Service (RADIUS) server that can accept authentication requests from RADIUS clients.
3.1. Troubleshooting the RADIUS Server Service
This section covers how to configure AM to troubleshoot the RADIUS Server service, and provides details about some specific issues that you might run into when using the RADIUS Server service.
3.1.1. Configuring for Troubleshooting the RADIUS Server Service
If you need to troubleshoot the RADIUS Server service, enable message-level debugging. For information about enabling debug logging, see "Debug Logging" in the Setup and Maintenance Guide.
With message-level debug logging enabled, AM writes messages to the
Radius debug log file when notable events occur,
including the following:
RADIUS server startup
Changes to the RADIUS server configuration
Successful and unsuccessful client connections
Various error events
You can also configure the RADIUS Server service to log the packets sent between RADIUS clients and AM. To enable packet logging, use the Log Packet Contents for this Client property when configuring RADIUS clients in the RADIUS Server service.
3.1.2. Solutions to Common RADIUS Server Service Issues
This section offers solutions to issues that you might encounter when configuring communication between RADIUS clients and the RADIUS Server service. The solutions assume that you have enabled message-level debugging for the RADIUS Server service in AM and have access to the debug logs.
- Client Cannot Connect
When a RADIUS client connects to AM's RADIUS server and hangs without receiving a response, the problem could be one of four possible issues:
The AM RADIUS Server service is not enabled.
An entry similar to the following in the
Radiusdebug log indicates that AM's RADIUS Server was started:
amRadiusServer:10/12/2015 12:00:14:814 PM PDT: Thread[RADIUS-1812-Listener,5,main]: TransactionId[27350419-8c21-429e-b580-35abf64604cf] RADIUS Listener is Active. Port : 1812 Threads Core : 2 Threads Max : 10 Thread Keep-alive : 10 sec Request Queue : 10
If no such entry exists in the debug log, re-examine the configuration for the RADIUS Server service and correct the problem.
The client is not defined.
An entry similar to the following in the
Radiusdebug log indicates the inability of a client to connect:
amRadiusServer:10/12/2015 04:05:53:681 PM PDT: Thread[RADIUS-1812-Listener,5,main]: TransactionId[270084d5-b7d0-42e4-8709-eeaeaf435aff] WARNING: No Defined RADIUS Client matches IP address /192.168.10.10. Dropping request.
To fix the problem, correct the client configuration in the RADIUS Server service.
The handler class for the client is incorrect.
An entry similar to the following in the
Radiusdebug log indicates an incorrect handler class:
ERROR: Configuration setting handlerClass in RADIUS Client configuration named 'TestClient' is invalid. Requests from this client will be ignored.
To fix the problem, correct the client configuration in the RADIUS Server service.
Traffic is not arriving at the AM server.
No specific debug log entries appear for this problem.
This is likely a network communication problem. Investigate the route for traffic between the RADIUS client and the AM RADIUS server to see where communication is lost.
- Authentication Always Fails
When authentication always fails, the probable cause is one of the following three issues:
The client secret configured for the client in the RADIUS Server service is incorrect.
Access-Requestpacket, the shared secret is used along with the random value sent in the request authenticator field to encrypt the password field value that is passed across the wire. If the client and server's shared secrets are not identical, the password expected by the server will not match the password sent by the client, resulting in authentication always failing. The user's password is always incorrect in such a scenario and there is no way for the server to differentiate between the client secret being incorrect and the password sent from the client being incorrect. The log file indicates that AM has sent an
Access-Rejectpacket to the client, similar to the action that would be taken if the shared secret matched on the client and server and the user entered an invalid password:
amRadiusServer:10/12/2015 04:27:55:785 PM PDT: Thread[RADIUS-1812-Listener,5,main]: TransactionId[270084d5-b7d0-42e4-8709-eeaeaf435aff] finalPacketType sent in response to auth request: 'ACCESS_REJECT'
Since the shared secret is specific to each client, such messages might appear for one RADIUS client, while other clients can authenticate successfully.
To fix this problem, correct the configuration for your client in the RADIUS Server service.
The realm configured for the client in the RADIUS Server service is incorrect.
An entry similar to the following in the
Radiusdebug log indicates an invalid realm in the RADIUS Server service configuration:
ERROR: Unable to start login process. Denying Access. com.sun.identity.authentication.spi.AuthLoginException: Domain is invalid| invalid_domain.jsp
If the realm is missing from the configuration, an error similar to the following appears:
ERROR: Unable to initialize declared handler class 'org.forgerock.openam.radius.server.spi.handlers.OpenAMAuthHandler' for RADIUS client ''. Rejecting access. java.lang.IllegalStateException: Configuration property 'realm' not found in handler configuration. It must be added to the Configuration Properties for this class in the Radius Client's configuration.
To fix this problem, correct the client configuration in the RADIUS Server service.
The authentication chain configured for the client in the RADIUS Server service is incorrect.
An entry similar to the following in the
Radiusdebug log indicates an invalid authentication chain in the RADIUS Server service configuration:
amRadiusServer:10/12/2015 05:32:21:771 PM PDT: Thread[pool-5-thread-2,5,main]: TransactionId[378a41cf-0581-4b62-a92f-be2b008ab4d3] ERROR: Unable to start login process. Denying Access.
If the chain is missing from the configuration, an error similar to the following appears:
ERROR: Unable to initialize declared handler class 'org.forgerock.openam.radius.server.spi.handlers.OpenAMAuthHandler' for RADIUS client ''. Rejecting access. java.lang.IllegalStateException: Configuration property 'chain' not found in handler configuration. It must be added to the Configuration Properties for this class in the Radius Client's configuration.
To fix this problem, correct the client configuration in the RADIUS Server service.
- Configuration Is Correct but Authentication Fails
In this case, you might have a client-specific problem. AM provides a tool that you can use to eliminate AM and its configuration as the cause of the problem. You can declare an alternate handler class implementation in the RADIUS Server service configuration. Two test handlers are available for troubleshooting purposes:
org.forgerock.openam.radius.server.spi.handlers.AcceptAllHandlerhandler always returns an
Access-Acceptpacket, indicating successful authentication for all requests.
org.forgerock.openam.radius.server.spi.handlers.RejectAllHandlerhandler always returns an
Access-Rejectpacket, indicating failed authentication for all requests.
In a case where you believe that configuration is correct but authentication always fails, you could specify the
org.forgerock.openam.radius.server.spi.handlers.AcceptAllHandlerhandler class in the RADIUS Server service configuration for your client. With packet logging enabled, all requests received from the client should log packet contents traffic similar to the following even if the password is incorrect:
WARNING: Packet from TestClient: ACCESS_REQUEST  - USER_NAME : demo - USER_PASSWORD : ******* - NAS_IP_ADDRESS : /127.0.0.1 - NAS_PORT : 0
This is followed by:
WARNING: Packet to TestClient: ACCESS_ACCEPT 
If the client still indicates that authentication has failed, refer to the documentation for the client to determine why the
Access-Acceptresponse is rejected. Most likely, the client expects specific fields in the
Access-Acceptresponse that are not provided by AM. There is currently no facility in AM to return fields in
- Authentication Always Succeeds, Even With a Bad Password
This would be a very unusual situation, probably due to the
org.forgerock.openam.radius.server.spi.handlers.AcceptAllHandlerhandler being left in place after troubleshooting an error scenario in which authentication always suceeds.
To resolve the problem, verify that the correct handler class is specified in the RADIUS Server service configuration for the client. If it is not specified, review the authentication modules in the chain that authenticates users and determine whether one of the modules might be accepting all authentication requests. This situation could also occur because of incorrectly-specified module criteria in the chain's definition.
3.2. RADIUS Server Limitations
Deploying AM's RADIUS server lets an organization consolidate RADIUS and HTTP authentication into a single solution, facilitating reuse of existing authentication mechanisms between both types of clients. However, there are several limitations:
Because RADIUS authentication attempts always start with a user name and password transmitted in an
Access-Requestpacket, the first module in an authentication chain used for RADIUS clients must accept a user name and a password.
By default, AM caches up to 5,000 RADIUS clients concurrently.
If necessary, you can change the maximum number of RADIUS clients that can be cached concurrently on an AM server by configuring the
org.forgerock.openam.radius.server.context.cache.sizeadvanced server property.
See "Configuring Servers" in the Reference for information about how to configure advanced server properties.
Some AM callback types are not applicable to RADIUS clients. For example, a
RedirectCallbackdirects HTTP clients, such as browsers, to HTTP resources to be used for some aspect of authentication. Redirects make no sense to RADIUS clients and cannot be consumed in any meaningful way.
ConfirmationCallbackalso presents challenges for RADIUS clients.
As a result, some AM authentication modules cannot be used with RADIUS clients. Before attempting to use an authentication module with RADIUS clients, review the module's callbacks to determine whether the module will support RADIUS clients. You can use the REST API to determine the callbacks for an authentication module as described in "Authentication and Logout using REST" in the Development Guide.
Some client mechanisms leveraged by authentication modules might not be applicable to RADIUS clients. For example, suppose a customized SMS one-time password module sends a one-time password over an SMS service, and then provides a
ChoiceCallbackthat enables the user to set a cookie in their browser that expires after 30 days. Such a module might first determine whether the cookie was available, still valid, and applicable to the current user before reissuing a new one-time and soliciting the value from the user.
RADIUS clients are unable to process HTTP cookies. Therefore, although RADIUS clients can support a
ChoiceCallback, the customized feature described in the previous paragraph would not function correctly for RADIUS clients and therefore should not be deployed with RADIUS clients. As a result, some callback sets within an authentication module will differ depending on the type of client being authenticated.
The RADIUS Server service logs only to the ForgeRock common audit logger introduced in OpenAM 13. It does not log to the classic audit logs that were available prior to OpenAM 13.
When building custom authentication modules, consider their suitability to handle the types of clients that might use them, and make adjustments to callbacks as needed.
Chapter 4. RADIUS Reference
This chapter covers configuration properties for the RADIUS server service feature, which is accessible through the Configure tab of the AM console, most of which can also be set by using the ssoadm command. The chapter is organized to follow the AM console layout.
4.1. RADIUS Server
amster service name:
The following settings appear on the Configuration tab:
Enables the AM RADIUS server to listen for requests on the listener port and to handle the requests.
The possible values for this property are:
- Listener Port
The UDP port on which each AM server will listen for RADIUS Access-Request packets
According to the RADIUS Authentication Specification, RFC 2865, the officially assigned port number for RADIUS is
1812. Specify a value from
65535. All client requests are handled through the same port.
- Thread Pool Core Size
When a RADIUS request is received and fewer than
corePoolSizethreads are running, a new thread is created to handle the request, even if other worker threads are idle. If there are more than "Thread Pool Core Size" but less than "Thread Pool Max Size" threads running, a new thread will be created only if the queue is full. By setting "Thread Pool Core Size" and "Thread Pool Max Size" to the same value, you create a fixed-size thread pool. Specify a value from
- Thread Pool Max Size
Maximum number of threads allowed in the pool. See also "Thread Pool Core Size".
- Thread Pool Keep-Alive Seconds
If the pool currently has more than Thread Pool Core Size threads, excess threads will be terminated if they have been idle for more than the Keep-Alive Seconds. Specify a value from
- Thread Pool Queue Size
The number of requests that can be queued for the pool before further requests will be silently dropped. See also "Thread Pool Core Size" and "Thread Pool Max Size". Specify a value from
4.1.2. Secondary Configurations
This service has the following Secondary Configurations.
- Client IP Address
The IP Address of the client.
Section 5.4 of the RADIUS Authentication Specification, RFC 2865, indicates that the source IP address of the Access-Request packet MUST be used to identify a configured client and hence determine the shared secret to use for decrypting the User-Password field.
This property should hold the source IP address of the client. This should match the value obtained from Java's
To verify the value, send an Access-Request packet to AM's RADIUS port and watch for a message stating:
"No Defined RADIUS Client matches IP address '/127.0.0.1'. Dropping request.". The value used in this property should match the IP address returned in the single quotes.
- Client Secret
This secret shared between server and client for encryption of the user password.
This secret must be conveyed to the RADIUS client and entered into its configuration before the User-Password field of incoming Access-Request packets can be decrypted to validate the password for the represented by that packet. A default value is generated for you but you can enter a custom value if desired.
- Log Packet Contents for this Client
Indicates if full packet contents should be dumped to the log.
When troubleshooting issues with RADIUS it is helpful to know what was received in a given packet. Enabling this feature will cause packet contents to be logged in a human consumable format. The only caveat is that the USER_PASSWORD field will be obfiscated by replacing with asterisks. This should only be enabled for troubleshooting as it adds significant content to logs and slows processing.
- Handler Class
The fully qualified name of a class to handle incoming RADIUS Access-Requests for this client.
This class must implement the
com.sun.identity.authentication.modules.radius.server.spi.AccessRequestHandlerinterface to handle incoming Access-Request packets and provide a suitable response. An instance of this class is created when configuration is first loaded to validate the class and then once for each new request. The configuration properties will only be passed for the request handling instances and not when validating the class.
- Handler Class Configuration Properties
Properties needed by the handler class for its configuration.
These properties are provided to the handler via its
initmethod prior to the call to handle the request packet. If these values are changed the next handler instance created for an incoming request will receive the updated values. Each entry assumes that the first '
=' character incurred separates a key from its value. All entries are placed in a properties file handed to each handler instance.

- Access control
Control to grant or to deny access to a resource.
- Account lockout
The act of making an account temporarily or permanently inactive after successive authentication failures.
Defined as part of policies, these verbs indicate what authorized identities can do to resources.
In the context of a policy decision denying access, a hint to the policy enforcement point about remedial action to take that could result in a decision allowing access.
- Agent administrator
User having privileges only to read and write agent profile configuration information, typically created to delegate agent profile creation to the user installing a web or Java agent.
- Agent authenticator
Entity with read-only access to multiple agent profiles defined in the same realm; allows an agent to read web service profiles.
In general terms, a service exposing protected resources.
In the context of AM policies, the application is a template that constrains the policies that govern access to protected resources. An application can have zero or more policies.
- Application type
Application types act as templates for creating policy applications.
Application types define a preset list of actions and functional logic, such as policy lookup and resource comparator logic.
Application types also define the internal normalization, indexing logic, and comparator logic for applications.
- Attribute-based access control (ABAC)
Access control that is based on attributes of a user, such as how old a user is or whether the user is a paying customer.
The act of confirming the identity of a principal.
- Authentication chaining
A series of authentication modules configured together which a principal must negotiate as configured in order to authenticate successfully.
- Authentication level
Positive integer associated with an authentication module, usually used to require success with more stringent authentication measures when requesting resources requiring special protection.
- Authentication module
AM authentication unit that handles one way of obtaining and verifying credentials.
The act of determining whether to grant or to deny a principal access to a resource.
- Authorization Server
In OAuth 2.0, issues access tokens to the client after authenticating a resource owner and confirming that the owner authorizes the client to access the protected resource. AM can play this role in the OAuth 2.0 authorization framework.
Arrangement to federate a principal's identity automatically based on a common attribute value shared across the principal's profiles at different providers.
- Bulk federation
Batch job permanently federating user profiles between a service provider and an identity provider based on a list of matched user identifiers that exist on both providers.
- Circle of trust
Group of providers, including at least one identity provider, who have agreed to trust each other to participate in a SAML v2.0 provider federation.
In OAuth 2.0, requests protected web resources on behalf of the resource owner given the owner's authorization. AM can play this role in the OAuth 2.0 authorization framework.
- Client-based OAuth 2.0 tokens
After a successful OAuth 2.0 grant flow, AM returns a token to the client. This differs from CTS-based OAuth 2.0 tokens, where AM returns a reference to token to the client.
- Client-based sessions
AM sessions for which AM returns session state to the client after each request, and require it to be passed in with the subsequent request. For browser-based clients, AM sets a cookie in the browser that contains the session information.
For browser-based clients, AM sets a cookie in the browser that contains the session state. When the browser transmits the cookie back to AM, AM decodes the session state from the cookie.
Defined as part of policies, these determine the circumstances under which which a policy applies.
Environmental conditions reflect circumstances like the client IP address, time of day, how the subject authenticated, or the authentication level achieved.
Subject conditions reflect characteristics of the subject like whether the subject authenticated, the identity of the subject, or claims in the subject's JWT.
- Configuration datastore
LDAP directory service holding AM configuration data.
- Cross-domain single sign-on (CDSSO)
AM capability allowing single sign-on across different DNS domains.
- CTS-based OAuth 2.0 tokens
After a successful OAuth 2.0 grant flow, AM returns a reference to the token to the client, rather than the token itself. This differs from client-based OAuth 2.0 tokens, where AM returns the entire token to the client.
- CTS-based sessions
AM sessions that reside in the Core Token Service's token store. CTS-based sessions might also be cached in memory on one or more AM servers. AM tracks these sessions in order to handle events like logout and timeout, to permit session constraints, and to notify applications involved in SSO when a session ends.
Granting users administrative privileges with AM.
Decision that defines which resource names can and cannot be accessed for a given identity in the context of a particular application, which actions are allowed and which are denied, and any related advice and attributes.
- Extended metadata

- Extensible Access Control Markup Language (XACML)
Standard, XML-based access control policy language, including a processing model for making authorization decisions based on policies.
Standardized means for aggregating identities, sharing authentication and authorization data information between trusted providers, and allowing principals to access services across different providers without authenticating repeatedly.
Service provider application capable of participating in a circle of trust and allowing federation without installing all of AM on the service provider side; AM lets you create Java Fedlets.

- Policy Administration Point (PAP)
Entity that manages and stores policy definitions.
- Policy Decision Point (PDP)
Entity that evaluates access rights and then issues authorization decisions.
- Policy Enforcement Point (PEP)
Entity that intercepts a request for a resource and then enforces policy decisions from a PDP.
- Policy Information Point (PIP)
Entity that provides extra information, such as user profile attributes that a PDP needs in order to make a decision.
Represents an entity that has been authenticated (such as a user, a device, or an application), and thus is distinguished from other entities.
When a Subject successfully authenticates, AM associates the Subject with the Principal.
In the context of delegated administration, a set of administrative tasks that can be performed by specified identities in a given realm.
- Provider federation
Agreement among providers to participate in a circle of trust.
AM unit for organizing configuration and identity information.
Realms can be used for example when different parts of an organization have different applications and identity stores, and when different organizations use the same AM deployment.
Administrators can delegate realm administration. The administrator assigns administrative privileges to users, allowing them to perform administrative tasks within the realm.
Something a user can access over the network such as a web page.
Defined as part of policies, these can include wildcards in order to match multiple actual resources.
- Resource owner
In OAuth 2.0, entity who can authorize access to protected web resources, such as an end user.
- Resource server
In OAuth 2.0, server hosting protected web resources, capable of handling access tokens to respond to requests for such resources.
- Response attributes
Defined as part of policies, these allow AM to return additional information in the form of "attributes" with the response to a policy decision.
- Role based access control (RBAC)
Access control that is based on whether a user has been granted a set of permissions (a role).
- Security Assertion Markup Language (SAML)
Standard, XML-based language for exchanging authentication and authorization data between identity providers and service providers.
- Service provider (SP)
Entity that consumes assertions about a principal (and provides a service that the principal is trying to access).
- Authentication Session
The interval while the user or entity is authenticating to AM.
The interval that starts after the user has authenticated and ends when the user logs out, or when their session is terminated. For browser-based clients, AM manages user sessions across one or more applications by setting a session cookie. See also CTS-based sessions and Client-based sessions.
- Session high availability
Capability that lets any AM server in a clustered deployment access shared, persistent information about users' sessions from the CTS token store. The user does not need to log in again unless the entire deployment goes down.
- Session token
Unique identifier issued by AM after successful authentication. For a CTS-based sessions, the session token is used to track a principal's session.
- Single log out (SLO)
Capability allowing a principal to end a session once, thereby ending her session across multiple applications.
- Single sign-on (SSO)
Capability allowing a principal to authenticate once and gain access to multiple applications without authenticating again.
Group of AM servers configured the same way, accessed through a load balancer layer. The load balancer handles failover to provide service-level availability.
The load balancer can also be used to protect AM services.
- Standard metadata
Standard federation configuration information that you can share with other access management software.
- Stateless Service
Stateless services do not store any data locally to the service. When the service requires data to perform any action, it requests it from a data store. For example, a stateless authentication service stores session state for logged-in users in a database. This way, any server in the deployment can recover the session from the database and service requests for any user.
Entity that requests access to a resource
When an identity successfully authenticates, AM associates the identity with the Principal that distinguishes it from other identities. An identity can be associated with multiple principals.
- Identity store
Data storage service holding principals' profiles; underlying storage can be an LDAP directory service or a custom
- Web Agent
Native library installed in a web server that acts as a policy enforcement point with policies based on web page URLs.
