Fixes, limitations, and known issues

Key fixes

The following issues are fixed in this release. For details, refer to the OpenAM issue tracker.

Amster 7.5

  • OPENAM-21747: Amster not working after connecting when AM REST call has extra set-cookie headers

  • OPENAM-21277: Running Amster in debug mode doesn’t work on Windows


Amster 7.5 has the following known limitations:

  • No support for load balanced deployments

    Amster cannot connect to a load balancer URL. You must connect Amster directly to a single AM instance. Using a load balancer could send sequential commands to different AM instances, and could result in concurrency issues when writing to the underlying configuration store.

  • Bulk import to external application stores with affinity

    If affinity is enabled for an external application data store, bulk import intermittently fails with errors similar to the following:

    Resource path 'http////////eea87a38e3ca476fa93a3669375ada3a' contains empty path elements

    Before using Amster for a bulk import to an application store, disable data store affinity, or remove the load balancer from the application store deployment. You can re-enable affinity when the import has completed.

  • Importing resources containing slash characters can fail

    Some Access Management resources have names that can contain slash characters (/), for example policy names, application names, and SAML v2.0 entities. These slash characters can cause unexpected behavior and failures in Amster when importing into Access Management instances running on Apache Tomcat.

    To workaround this issue, configure Apache Tomcat to allow encoded slash characters by updating the CATALINA_OPTS environment variable. For example:

    On Unix/Linux systems:

    $ export CATALINA_OPTS= \

    On Windows systems:

    C:\> set CATALINA_OPTS= ^
    C:\> startup.bat
    It’s strongly recommended that you do not enable org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH when running AM in production as it introduces a security risk on Apache Tomcat.
  • [INFO] messages showing on SuSE on Amster start up

    Running Amster on SuSE may produce [INFO] messages, for example:

    # ./amster
    [INFO] Unable to bind key for unsupported operation: up-history
    [INFO] Unable to bind key for unsupported operation: down-history
    [INFO] Unable to bind key for unsupported operation: up-history
    [INFO] Unable to bind key for unsupported operation: down-history
    OpenAM Shell (version build build, JVM: version)
    Type ':help' or ':h' for help.

    These messages are caused by the keyboard mappings configured in the /etc/inputrc file and can safely be ignored, as they do not affect functionality.
