Configure a remote connector server RCS

RCS runs in one of two modes:

Client mode: In client mode, RCS initiates the connection with IDM. Run the RCS in client mode if you need to communicate with a system that is behind a firewall and IDM is outside that firewall (such as Identity Cloud).

The following diagram shows an RCS in client mode:
Server mode: In server mode, RCS acts as the server, with IDM acting as a client. IDM initiates the connection with the RCS. Run the RCS in server mode if IDM can initiate the connection.

The following diagram shows an RCS in server mode:

This example shows how to retrieve the RCS types over REST:

RCS configuration properties

The following table displays the complete list of RCS configuration properties with truncated property names for readability. The full name for each property is prefixed with connectorserver. in the conf/ConnectorServer.properties configuration file included with RCS.

Time interval properties

The default values for the nameInterval and webSocketConnections properties are suitable for most RCS deployments. Do not adjust these property values without specific guidance from ForgeRock.

Property RCS Mode (Server or Client) Description Example

connectorServerName

Client

Name of the remote connector client. This name is used to identify the remote connector server in the list of connector reference objects. The name must be lower case alphanumeric characters (^[a-z0-9]*$), and must match the name property in the provisioner.openicf.connectorinfoprovider.json file on your IDM server.

rcs1

url

Client

URL of the server on which IDM runs. This property can have multiple values. When using multiple values, separate each address with a space.

wss://openidm.example.com:8443/openicf ^[1]

1. Note the wss (WebSocket transport protocol) and the openicf endpoint.

hostId

Client

Unique identifier for the RCS.

MY_UNIQUE_RCS_HOST_ID

proxyHost

Client

Proxy server host.

proxyPort

Client

Proxy server port number.

proxyPrincipal

Client

Proxy server principal.

proxyPassword

Client

Proxy server password.

housekeepingInterval

Client

Interval at which RCS checks WebSockets to determine if they should be closed and recycled according to the specified interval, in seconds.

groupCheckInterval

Client

Interval at which RCS checks WebSocket connection groups (group of WebSocket connections associated with the same IDM <-> RCS link) to see if they should be closed, in seconds. WebSocket connection groups are closed when they no longer contain any active WebSocket connections.

webSocketConnections

Client

Number of WebSocket connections to open.

connectionTtl

Client

Time to live of a WebSocket connection, in seconds.

newConnectionsInterval

Client

Interval at which RCS establishes new WebSocket connections, in seconds. Ensures that connection establishment is staggered.

tokenEndpoint

Client

Token endpoint from which to retrieve the access token if you are using OAuth2 to authenticate against AM.

https://am.example.com/am/oauth2/realms/root/access_token

scope

Client

OAuth2 token scope, if you are using OAuth2 to authenticate against AM.

fr:idm:*

clientId

Client

OAuth2 Client ID for which to request an access token.

connectorServer

If the RCS is authenticating against AM, you must update your IDM authentication configuration (in conf/authentication.json). Add a user mapping for this client ID in the rsFilter authentication module configuration. For more information, refer to Authenticate through AM.

clientSecret

Client

OAuth2 Client Secret.

openidm

pingPongInterval

Both

Interval at which RCS sends ping/pong messages between IDM <-> RCS, in seconds. Used to determine health/connectivity of the underlying WebSocket connection. The purpose of the ping is to keep connections alive (for firewalls or load balancers that honor connections in use). If your firewall or load balancer doesn’t honor connections in use (that is, connections are timed out, regardless of their usage), the ping has no effect, and you should disable it. Set this property to 0 to disable the ping.

ICFServlet configuration options

You can configure the following optional ICFServlet settings in your conf/provisioner.openicf.connectorinfoprovider.json file:

maxMessageSize: Integer.

You can set a maximum message size in kilobytes. The default is 20MB.
idleTimeout: Integer.

The maximum time, in minutes, that a WebSocket connection can be idle before it is removed. The default is 15 minutes.

Example provisioner.openicf.connectorinfoprovider.json:

{
  "_id": "provisioner.openicf.connectorinfoprovider",
  "connectorsLocation": "connectors",
  "ICFServlet": {
    "maxMessageSize": 40960,
    "idleTimeout": 23
  },
  ...
}

Configure RCS in client mode

The RCS configuration will differ between server mode and client mode. Refer to RCS Properties for a list of properties and the mode to which they apply.

To generate the core configuration, use the createConnectorServerCoreConfig action on the system endpoint. Include at least the RCS type (remoteConnectorClient) and the systemType in the JSON payload. The systemType is always provisioner.openicf, regardless of the RCS type:

Create a core RCS configuration (client mode)

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--header "Content-Type: application/json" \
--request POST \
--data '{
  "type": "remoteConnectorClient",
  "systemType": "provisioner.openicf"
}' \
"http://localhost:8080/openidm/system?_action=createConnectorServerCoreConfig"
{
  "displayName": "",
  "name": "",
  "enabled": true,
  "usessl": false
}

IDM returns the basic configuration properties for an RCS in client mode. The configuration that is returned is not functional. It does not contain the required configuration property values, such as the name of the RCS.

Use the output returned by the previous example to create your complete RCS configuration. Specify at least the name of the RCS, and use a PUT request on the config endpoint. Note that this step creates an RCS configuration on IDM. The values of these properties must match the RCS configuration, specified in the ConnectorServer.properties file on the RCS:

Create a new RCS configuration (client mode)

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--header "Content-Type: application/json" \
--request PUT \
--data '{
  "_id": "provisioner.openicf.connectorinfoprovider",
  "connectorsLocation": "connectors",
  "enabled": true,
  "remoteConnectorClients": [
    {
      "displayName": "On premise 1",
      "name": "onprem",
      "enabled": true
    }
  ]
}' \
"http://localhost:8080/openidm/config/provisioner.openicf.connectorinfoprovider"
{
  "_id": "provisioner.openicf.connectorinfoprovider",
  "connectorsLocation": "connectors",

  "remoteConnectorClients": [
    {
      "displayName": "On premise 1",
      "name": "onprem",
      "enabled": true
    }
  ]
}

Configure RCS in server mode

Server mode is not compatible with Identity Cloud. If you are using Identity Cloud, configure RCS in client mode instead.

The RCS configuration will differ between server mode and client mode. Refer to RCS Properties for a list of properties and the mode to which they apply.

To generate the core configuration, use the createConnectorServerCoreConfig action on the system endpoint. Include at least the RCS type (remoteConnectorServer) and the systemType in the JSON payload. The systemType is always provisioner.openicf, regardless of the RCS type:

Create a Core RCS Configuration (Server Mode)

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--header "Content-Type: application/json" \
--request POST \
--data '{
  "type": "remoteConnectorServer",
  "systemType": "provisioner.openicf"
}' \
"http://localhost:8080/openidm/system?_action=createConnectorServerCoreConfig"
{
  "displayName": "",
  "proxyPassword": null,
  "proxyHost": null,
  "enabled": true,
  "usessl": false,
  "proxyPort": 8080,
  "port": "",
  "name": "",
  "host": "",
  "proxyUser": null,
  "housekeepingInterval": 600,
  "connectionGroupCheckInterval": 60,
  "pingPongInterval": 300,
  "key": "password",
  "webSocketConnections": 2
}

IDM returns the required configuration properties for an RCS in server mode. The configuration that is returned is not functional. It does not contain the specific property values, such as the host name and port of the RCS.

Use the output returned by the previous example to create your complete RCS configuration. Specify at least the host and port of the RCS, and use a PUT request on the config endpoint. Note that this step creates an RCS configuration on IDM. The values of these properties must match the RCS configuration, specified in the ConnectorServer.properties file on the RCS:

Create a New RCS Configuration (Server Mode)

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \

}

Configure failover between RCS servers

For failover purposes, you can configure a group of RCSs, in either server or client mode. Failover is particularly important when you configure an RCS in client mode because IDM has no way of knowing whether the RCS is available.

To prevent the RCS from being a single point of failure, you can specify a list of RCS servers that the connector can target. To set up a failover configuration, you create either a remoteConnectorServersGroup or a remoteConnectorClientsGroup and list the RCS servers. The connector attempts to contact the first RCS in the list. If that RCS is down, it proceeds to the next RCS.

Configure failover for RCS servers in client mode

This example configures a remoteConnectorClientsGroup that lists two remote RCS servers, on hosts remote-host-1 and remote-host-2. The RCS servers are listed by their name property. You can configure multiple groups and multiple servers per group.

First, generate the core configuration to obtain the required properties:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--header "Content-Type: application/json" \
--request POST \
--data '{
  "type" : "remoteConnectorClientsGroup",
  "systemType" : "provisioner.openicf"
}' \
"http://localhost:8080/openidm/system?_action=createConnectorServerCoreConfig"
{
   "displayName": "",
   "name": "",
   "serversList": [],
   "algorithm": "failover"
 }

Use the output returned by the previous example to create your RCS group configuration. Use a PUT request on the config endpoint:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--header "Content-Type: application/json" \
--request PUT \
--data '{
  "_id": "provisioner.openicf.connectorinfoprovider",
  "connectorsLocation": "connectors",
  "enabled": true,
  "remoteConnectorClients": [
    {
      "type": "remoteConnectorClientsGroup",
      "displayName": ".NET Failover Group",
      "name" : "dotnet-ha",
      "algorithm" : "failover",
      "serversList" : [
        {"name": "remote-host-1"},
        {"name": "remote-host-2"}
      ]
    }
  ]
}' \
"http://localhost:8080/openidm/config/provisioner.openicf.connectorinfoprovider"
{
  "_id": "provisioner.openicf.connectorinfoprovider",
  "connectorsLocation": "connectors",
  "enabled": true,
  "remoteConnectorClients": [
    {
      "type": "remoteConnectorClientsGroup",
      "displayName": ".NET Failover Group",
      "name": "dotnet-ha",
      "algorithm": "failover",
      "serversList": [
        {
          "name": "remote-host-1"
        },
        {
          "name": "remote-host-2"
        }
      ]
    }
  ]
}

The algorithm can be either failover or roundrobin. If the algorithm is failover, requests are always sent to the first RCS in the list, unless it is unavailable; in which case, requests are sent to the next RCS in the list. If the algorithm is roundrobin, requests are distributed equally between the RCS servers in the list, in the order in which they are received.

Your connector configuration (provisioner.openicf-connector-name.json) references the RCS group, rather than a single RCS. For example, the following excerpt of a PowerShell connector configuration file references the dotnet-ha RCS group created in the previous example:

{
   "connectorRef" : {
     "bundleName" : "MsPowerShell.Connector",
     "connectorName" : "Org.ForgeRock.OpenICF.Connectors.MsPowerShell.MsPowerShellConnector",
     "connectorHostRef" : "dotnet-ha",
     "bundleVersion" : "[1.4.3.0,1.5.0.0)"
   },
   ...
 }

Configure failover for RCS servers in server mode

This example configures a remoteConnectorServersGroup that lists two remote RCS servers, on hosts remote-host-1 and remote-host-2. The RCS servers are listed by their name property. You can configure multiple groups and multiple servers per group.

First, generate the core configuration to obtain the required properties:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--header "Content-Type: application/json" \
--request POST \
--data '{
  "type" : "remoteConnectorServersGroup",
  "systemType" : "provisioner.openicf"
}' \
"http://localhost:8080/openidm/system?_action=createConnectorServerCoreConfig"
{
   "displayName": "",
   "name": "",
   "serversList": [],
   "algorithm": "failover"
 }

Use the output returned by the previous example to create your RCS group configuration. Use a PUT request on the config endpoint:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--header "Content-Type: application/json" \
--request PUT \
--data '{

      "serversList" : [
        {"name": "remote-host-1"},
        {"name": "remote-host-2"}
      ]
    }
  ]

   },
   ...
 }

Secure the connection to the RCS with SSL

The following section does not apply to Identity Cloud, as it requires filesystem access to your installation.

The SSL configuration for an RCS depends on whether you are running the RCS in server mode or in client mode:

In server mode, IDM initiates the connection to the RCS.

The RCS needs a public/private key pair and a certificate (either self-signed or CA-signed). The RCS sends its certificate to the client (IDM) during the SSL handshake.

If you are using a CA-signed certificate, IDM will trace the certificate back to the root certificate. If you are using a self-signed certificate (or a certificate that depends on an unreachable issuer in the chain from the root certificate), you must import the certificate into the IDM truststore.
In client mode, the RCS initiates the connection to IDM. IDM sends its certificate during the SSL handshake. If you are using the IDM self-signed certificate, you must import the certificate into the RCS truststore.

If you are using TLS Mutual Authentication, the RCS needs a public/private key pair and a certificate. IDM requests the certificate from the RCS during the SSL handshake.

Configure the RCS for SSL

On the RCS, edit the conf/ConnectorServer.properties file to specify a secure connection between IDM and the RCS:

RCS in server mode

Set connectorserver.usessl=true.

Specify the RCS keystore and truststore. For example:

connectorserver.trustStoreFile=security/truststore.pkcs12
connectorserver.trustStoreType=PKCS12
connectorserver.trustStorePass=changeit
connectorserver.keyStoreFile=security/keyStore.pkcs12
connectorserver.keyStoreType=PKCS12
connectorserver.keyStorePass=changeit
connectorserver.keyPass=changeit

RCS in client mode

Connection security is determined by the value of the connectorserver.url property. Use the wss protocol to establish a WebSocket over an encrypted TLS connection; for example, wss://my-tenant.forgeblocks.com/openicf.

The connectorserver.usessl property is not used in client mode.

Specify the RCS keystore and truststore. For example:

connectorserver.trustStoreFile=security/truststore.pkcs12
connectorserver.trustStoreType=PKCS12
connectorserver.trustStorePass=changeit
connectorserver.keyStoreFile=security/keyStore.pkcs12
connectorserver.keyStoreType=PKCS12
connectorserver.keyStorePass=changeit
connectorserver.keyPass=changeit

Configure IDM for SSL

In your conf/provisioner.openicf.connectorinfoprovider.json file, set "usessl" : true.

Generate keys for an RCS in server mode

Generate the RCS private/public key pair and create a new PKCS12 keystore:

keytool \
-genkeypair \
-keyalg EC \
-alias icf-rcs \
-dname "CN=icf.example.com,O=Example Corp,C=FR" \
-keystore rcsKeystore \
-storetype PKCS12 \
-storepass changeit \

Verify the contents of the new keystore:

keytool \
-list \
-v \
-keystore rcsKeystore
Enter keystore password:  changeit
Keystore type: PKCS12
Keystore provider: SUN

Your keystore contains 1 entry
