AM 7.3.1

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.

Install and configure Directory Services 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. In most cases, users will need to log in again so that AM stores their sessions and tokens in the new token store.

Test Session High-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.

Test session availability

Install and configure Directory Services for CTS data

Installing DS with a DS setup profile creates the required backend, schema, bind user, and indexes:

  1. Follow the steps in Install DS for AM CTS in the DS documentation.

  2. 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

    1. Export the DS server certificate:

      $ keytool -exportcert \
-keystore /path/to/opendj/config/keystore \
-storepass:file /path/to/opendj/config/keystore.pin \
-alias ssl-key-pair \
-rfc \
-file ds-cert.pem

      The default DS server certificate only has the hostname you supplied at setup time, and localhost, as the value of the SubjectAlternativeName attribute; however, certificate hostname validation is strict. Ensure that the certificate matches the hostname (or the FQDN) of the DS server before continuing.

      Copy the ds-cert.pem file to an accessible location on the AM host.

    2. Import the DS certificate into the AM truststore:

      $ keytool \
-importcert \
-file ds-cert.pem \
-keystore /path/to/openam/security/keystores/truststore

    For more information on configuring AM’s truststore, see Prepare the truststore.

  3. 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:

  1. In the AM admin UI, go to Configure > Server Defaults, and click CTS.

  2. 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

  3. 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. Alternatively, use the LDAP port with StartTLS, as in 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

    For production, this value needs to be tuned.

  4. Save your work.

  5. 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.

  1. In Chrome, log in to the second AM instance with the amAdmin user, click the realm, and click Sessions.

  2. In Firefox, log in to the first AM instance with a test user.

  3. In Chrome, verify that the test user exists in the first AM instance’s session list and not in the second instance.

  4. Shut down the first AM instance.

  5. In Firefox, rewrite the URL to point to the second AM instance.

    If successful, the browser should not prompt for login.

  6. Confirm the session is still available.

    In Chrome, list the sessions on the second instance, the test user’s session should be present.

  7. Restart the first AM instance to complete the testing.
