Error description

  • Adding a 85517+ node from 9051+ DMGR fails with CWWIM5106E
    indicating the down-level node doesn't support the
    PBKDF2WithHmacSHA1 hashing algorithm when 85517+ does support
    it.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server                                      *

    * PROBLEM DESCRIPTION: Adding 8.5.5.17+ node from 9.0.5.1+     *
    *                      deployment manager fails with           *
    *                      CWWIM5106E.                             *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When adding a 8.5.5.17+ node from a 9.0.5.1+ deployment
    manager, the following exception may be encountered:
    CWWIM5106E The [InternalFileRepository] repositories in the
    "admin" security domain use the PBKDF2WithHmacSHA1 hashing
    algorithm that is not supported by the node being added.
     »
    The PBKDF2WithHmacSHA1 algorithm was delivered in 8.5.5.17 and
    9.0.5.1 and these checks were added to prevent configuring a
    down-level node with a hashing algorithm that it did not
    support. However; 8.5.5.17+ does indeed support the new
    algorithm. The issue is due to errant code that was checking
    the major version of the deployment manager instead of the
    node being added.
    Note, the CwWIM5106E error message is expected when the node
    being added is not a version that supports the new hashing
    algorithm.
    

Problem conclusion

  • Update the version checks to check against the proper major
    version of the node instead of major version of the DMGR.
    
    The fix for this APAR is targeted for inclusion in fix packs
    8.5.5.18 and 9.0.5.4. For more information, see 'Recommended
    Updates for WebSphere Application Server':
