Limitations
The following limitations are inherent to the design, not bugs to be fixed.
Redundant files
The installation and upgrade wizards use three libraries that you should remove for security reasons.
When your installation or upgrade is complete, remove the following .jar files from the WEB-INF/lib directory:
-
click-extras-2.3.0.jar -
click-nodeps-2.3.0.jar -
velocity-1.7.jar
These files are used only by the wizards. Removing them will have no effect on your installed instance.
Evaluation installations
Sometimes, installing AM for evaluation purposes will fail with a message similar to the following
if the JDK’s default truststore’s permissions are 444:
$JAVA_HOME/lib/security/cacerts (Permission denied), refer to install.log under /path/to/install.log for more information.
To work around this issue, locate the truststore that your container is using and change its permissions to 644 before
installing AM:
$ sudo chmod 644 $JAVA_HOME/lib/security/cacerts
You can change the permissions to their original settings after you have installed AM.
Identity and data store scaling
The connection strings to the data or identity stores are static and not hot-swappable. This means that, if you expand or contract your DS affinity deployment, AM will not detect the change. To work around this, either:
-
Manually add or remove the instances from the connection string and restart AM or the container where it runs.
-
Configure a DS proxy in front of the DS instances to distribute data across many DS shards, and configure the proxy address in the connection string.
SAML v2.0 in the AM admin UI
The AM admin UI supports SAML v2.0 IDP and SP entities only. After upgrade, entities that don’t have IDP or SP roles are listed, but you can’t inspect or edit them in the UI. AM displays an error when you try to access these entities.
Entities that contain roles other than IDP or SP will only display the IDP or SP roles.
Web Authentication (WebAuthn)
AM doesn’t support the following functionality, as described in the Web Authentication specification:
- Registration
-
-
AM doesn’t support Token Binding.
-
Web Authentication extensions aren’t supported.
-
Credential ID values aren’t verified against the credential IDs registered with all existing users.
-
The ECDAA signature of the Packed attestation format isn’t supported.
-
- Authentication
-
-
Token Binding isn’t supported.
-
Web Authentication extensions aren’t supported.
-
Signature counters aren’t supported.
-
Refer to MFA: Web Authentication (WebAuthn) for more information.
RADIUS service only supports commons audit logging
The RADIUS service only supports Commons Audit Logging and can’t use the older Logging Service, available in releases before OpenAM 13.0.0.
AM admin UI access requires the Realm Admin privilege
In this version of AM, administrators can use the AM admin UI as follows:
-
Delegated administrators with the
Realm Adminprivilege can access full AM admin UI functionality within the realms they administer. In addition, delegated administrators in the Top Level Realm who have this privilege can access AM’s global configuration. -
Administrators with fewer privileges, such as the
Policy Adminprivilege, can’t access the AM admin UI. -
The top-level administrator, such as
amAdmin, has access to full AM admin UI functionality in all realms and can access AM’s global configuration.
Specifying keys in JWT headers
AM ignores keys specified in JWT headers, such as jku and jwe. Configure the public keys or certificates in
AM instead, as explained in the relevant sections of the documentation.
Different AM versions within a site
Different AM versions within a site aren’t supported. Don’t run different versions of AM together in the same AM site.
Special characters in policy, application, or referral names
Don’t use special characters in policy, application or referral names (for example, "my+referral"). AM returns a 400 Bad Request error. The special characters are:
-
double quotes (")
-
plus sign (+)
-
comma (,)
-
less than (<)
-
equals (=)
-
greater than (>)
-
backslash (\)
-
null (\u0000)
