Configure CTS token stores
The following table summarizes the high-level tasks you must perform to configure a new instance of the CTS token store:
Task | Resources |
---|---|
Prepare a DS server Prepare the DS schema for CTS data. |
|
Configure AM to use the new CTS token store Configuring a new CTS data store does not migrate existing data from the old store to the new one. Usually, users will need to log in again so that AM stores their sessions and tokens in the new token store. |
|
(Optional) Configure mTLS authentication to the CTS store By default, AM authenticates to the CTS store using simple (username/password) authentication. To enhance security, you can configure mutual TLS (mTLS) authentication which lets AM authenticate using a trusted certificate. |
|
Test session availability For this test, you must have a site with more than one instance. The idea is to log in a user into the first instance, shut it down, and check that the session is still available to the second instance. |
Install and configure Directory Services for CTS data
Installing DS with a setup profile creates the required backend, schema, bind user, and indexes:
-
Follow the steps in Install DS for AM CTS in the DS documentation.
-
Share the CTS store certificate with the AM container to prepare for TLS/LDAPS. The CTS store should communicate over secure connections for security reasons.
DS 7 and later requires secure connections by default; therefore, share its certificate with the AM container before continuing.
Share the DS certificate with AM
-
On the DS host, export the DS CA certificate.
DS uses a deployment ID and password to generate a CA key pair. Learn more in Deployment IDs.
Use the
dskeymgr
command to export the CA certificate:$ /path/to/opendj/bin/dskeymgr \ export-ca-cert \ --deploymentId $DEPLOYMENT_ID \ --deploymentIdPassword password \ --outputFile /path/to/ca-cert.pem
-
Copy the
ca-cert.pem
file to an accessible location on the AM host.
-
Import the DS certificate into the AM truststore:
$ keytool \ -importcert \ -file /path/to/ca-cert.pem \ -keystore /path/to/openam/security/keystores/truststore
Learn more about configuring AM’s truststore in Prepare the truststore.
-
-
Configure the CTS store in AM.
Refer to Configure the CTS.
The bind DN of the service account to use when configuring the CTS store in AM is
uid=openam_cts,ou=admins,ou=famrecords,ou=openam-session,ou=tokens
.
Configure the CTS
This procedure assumes that the AM instances communicate with a single CTS instance (or load balancer),
which has an FQDN of cts.example.com
and is running on port 1636
.
If AM cannot access the CTS token store, you will be unable to log in to the AM admin UI. Back up your deployment before making any changes to your CTS token store configuration. |
Perform the following steps to configure an external CTS token store:
-
In the AM admin UI, go to Configure > Server Defaults, and click CTS.
-
On the CTS Token Store tab, set the following parameters:
CTS Token Store Parameters Parameter Value Notes Store Mode
External Token Store
Root Suffix
ou=famrecords,ou=openam-session,ou=tokens
-
On the External Store Configuration tab, configure the parameters as follows:
External Store Configuration Parameters Parameter Value Notes SSL/TLS Enabled
True
When connecting to DS 7, or a DS server in production mode, enable secure connections. When you enable SSL/TLS, make sure the AM server can trust the DS server certificate and that the certificate matches the CTS store FQDN.
Connection String(s)
cts.example.com:1636
Use the LDAPS port or the LDAP port with StartTLS (
cts.example.com:1389
).Login ID
uid=openam_cts,ou=admins,ou=famrecords,ou=openam-session,ou=tokens
The bind DN of the service account AM uses to connect to the directory service.
Password
5up35tr0ng
Use a strong bind password for production systems.
Heartbeat
10
Tune this value for production systems.
-
Save your work.
-
Restart AM or the web container where it runs for the changes to take effect.
Test session availability
To test session availability, use two browsers: Chrome and Firefox. You can use any two browser types, or run the browsers in incognito mode. You can also view tokens using an LDAP browser.
-
In Chrome, log in to the second AM instance with the
amAdmin
user, click the realm, and click Sessions. -
In Firefox, log in to the first AM instance with a test user.
-
In Chrome, verify that the test user exists in the first AM instance’s session list and not in the second instance.
-
Shut down the first AM instance.
-
In Firefox, rewrite the URL to point to the second AM instance.
If successful, the browser won’t prompt for login.
-
Confirm the session is still available.
In Chrome, list the sessions on the second instance and observe the test user’s session.
-
Restart the first AM instance to complete the testing.
