Changes to Existing Functionality

By default, AM rejects any JWT that expands to more than 32 KiB (32768 bytes) when decompressed. For more information about changing this default value, see "Controlling the Maximum Size of Compressed JWTs".

By default, AM rejects incoming requests with a body larger than 1 MB (1048576 bytes) in size. For more information about changing this default value, see "Limiting the Size of the Request Body".

This change affects AM when acting as an OAuth 2.0 and OpenID Connect client.

If a redirection URI uses a scheme, host, or port that differs from that of AM, you must now add it to the global validation service to ensure that it is pre-approved. This is described in "Configuring Success and Failure Redirection URLs".

Otherwise, AM rejects the URI, and redirection fails.

The subject claim of access tokens and ID tokens has changed formats to ensure that it is locally unique. The new format is not enforced after upgrading to AM 7.1, but new installations default to it.

The org.forgerock.security.oauth2.enforce.sub.claim.uniqueness advanced server property controls the format of the sub claim.

Before enabling it, ensure that your clients can use the new sub claim format, or a combination of the sub and the subname claims.

The new Save Retry Limit to User feature in this node is enabled by default after upgrade and requires upgrading the identity store schema.

Ensure you update the schema following the instructions in Upgrading AM Instances, or disable the feature. ForgeRock recommends keeping it enabled for security reasons.

Failure to take any of the actions will break the authentication journey for trees using this node.

One-time passwords created by the "HOTP Generator Node" are now stored in the authentication tree's transient state.

Modify any custom authentication nodes or scripts used by the "Scripted Decision Node" to retrieve the one-time passwords from the transient state after upgrading to AM 7.1.

The profile attribute whitelist controls the information returned to non-administrative users when accessing json/user endpoints.

Common profile attributes are whitelisted by default, but you need to add any custom attribute you want your non-administrative users to see. For more information, see "Configuring the User Profile Whitelist".

When a client makes a call to the /json/authenticate endpoint appending a valid SSO token, AM returns the tokenId field empty if HttpOnly cookies are enabled. For example:

{
    "tokenId":"",
    "successUrl":"/openam/console",
    "realm":"/alpha"
}

An AES 256-bit key called directenctest must be available in the environment during upgrade, but it does not need to be the same key that AM provides on the default keystore.

After upgrade, ensure that the am.authn.trees.transientstate.encryption secret ID is always mapped to an existing, resolvable secret or key alias. Failure to do so may result in trees not working as expected.

The embedded DS can only be used for single AM instances, for test and demo purposes. Sites are not supported.

Sites using embedded DS servers must be migrated to external DS servers before upgrading.

AM 7 migrated SAML v2.0 to use secret stores. The upgrade process only creates the secret store files on the AM instance where you ran the upgrade process. For more information, see "Configuring Secret Stores After Upgrade".

Redirection URLs for authentication services, agents, and SAML v.2.0 must be configured in the Validation Service if they are not in the same scheme, FQDN, and port as AM, or are not relative to AM's URL.

Several properties that used to be configured as custom properties (com.sun.identity.agents.config.freeformproperties) have been added as regular properties. Due to this change, upgrading to AM 7 will overwrite the value of the original custom properties with the default value of the new UI properties.

To work around this issue, perform one of the following actions:

AM 7 changes the way the CTS reaper searches for expired tokens.

After upgrading, retune the CTS Reaper using the information in "Reaper Search Size".

OpenID Connect clients authenticating with JWTs must include in the JWT a jti claim containing a unique identifier, in line with OpenID Connect Core 1.0 incorporating errata set 1.

AM flags cookies as secure if they come through a connection marked as secure, or if they come through HTTPS. See "Managing the Secure Cookie Filter".

AM only issues refresh tokens to clients that have the refresh token grant type configured in their client profile.

After an upgrade to 6.5 or later using the UI or the openam-upgrade-tool .jar file, existing OAuth 2.0 clients are configured to use all grant flows, including the Refresh Token Grant flow.

To configure the refresh token grant type manually, see "To Configure AM to Issue Refresh Tokens".

Recovery Codes are encrypted, and existing codes are no longer displayed to the user. For more information, see "Upgrading Device Recovery Codes".

AM 6.5 introduced secret stores for OAuth 2.0 and the persistent cookie module. The upgrade process only creates the secret store files on the AM instance where you ran the upgrade process. For more information, see "Configuring Secret Stores After Upgrade".

DS 6.5 introduced setup profiles, which pre-configure instances for different usages, such as CTS or configuration data. The default base DN for a DS configuration store instance (ou=am-config) is different than the default used by previous versions of AM (dc=openam,dc=forgerock,dc=org).

You should not attempt to run multiple instances of AM where the configuration store base DNs do not match. Use the same configuration store base DNs when configuring external DS 6.5+ instances that will be used simultaneously alongside existing DS 6 or earlier configuration store instances.

For more information, see "Preparing Configuration Stores".

AM's CSRF protection filter requires that either the X-Requested-With or the Accept-API-Version headers are included on requests to endpoints under the json root. For more information, see "Reviewing REST API Versions Before Upgrading".
