PM70338: CANNOT DYNAMICALLY UPDATE A SHARED LIBRARY BEING USED BY A TRUST ASSOCIATION INTERCEPTOR (TAI)

8.5.0.1: WebSphere Application Server V8.5 Fix Pack 1
8.5.0.2: WebSphere Application Server V8.5 Fix Pack 2

APAR status

• Closed as program error.

Error description

• If using a trust assocition interceptor with a libraryRef to a
  shared library such as:
  
      <trustAssociation id="myTAIConfig"
  invokeForUnprotectedURI="false" invokeForFormLogin="false"
  failOverToAppAuthType="false">
          <interceptors id="myTAI"
  className="com.ibm.ws.security.authentication.tai.fat.CustomTAI"
   enabled="true" invokeBeforeSSO="true" invokeAfterSSO="true"
  libraryRef="customTAILib">
              <properties scenario="subject" username="user2"/>
          </interceptors>
      </trustAssociation>
      <library id="customTAILib">
          <fileset dir="${server.config.dir}"
  includes="CustomTAI.jar"/>
      </library>
  
  and the library is converted from the libraryRef to a nested
  library such as:
  
   <trustAssociation id="myTAIConfig"
  invokeForUnprotectedURI="false" invokeForFormLogin="false"
  failOverToAppAuthType="false">
          <interceptors id="myTAI"
  className="com.ibm.ws.security.authentication.tai.fat.CustomTAI"
   enabled="true" invokeBeforeSSO="true" invokeAfterSSO="true">
              <properties scenario="hashtable" username="user2"/>
        <library id="customTAILib">
            <fileset dir="${server.config.dir}"
  includes="CustomTAI.jar"/>
        </library>
          </interceptors>
      </trustAssociation>
  
  then this update is not reflected in the server.

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server Liberty Profile using TAI.           *
  ****************************************************************
  * PROBLEM DESCRIPTION: The trust association interceptor       *
  *                      cannot start because it can not find    *
  *                      the shared library.                     *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Liberty profile servers using trust association interceptors
  with a shared library do not dynamically update when
  the configuration XML is updated to include the shared library
  as a nested library rather than a libraryRef.
  

Problem conclusion

• The shared reference cardinality was updated to reflect the
  inclusion of nested shared libraries.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.0.1. Please refer to the Recommended Updates page
