Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty collectives configured with  *
    *                  BYO SSH keys                                *
    ****************************************************************
    * PROBLEM DESCRIPTION: When using a "bring your own" SSH key,  *
    *                      multiple copies of the key can be       *
    *                      appended to the authorized_keys file.   *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When using a "bring your own" SSH key, the key will get appended
    to the authorized_keys file every time a collective controller
    is started, even if the key already exists in the file.
    

Problem conclusion

  • The code was updated to ensure the authorized_keys file is not
    appended if it already has a reference to the key.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 20.0.0.2.  Please refer to the Recommended Updates page for
    delivery information:
    http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
    

Temporary fix

  • As a workaround, ensure there are no leading (or trailing)
    spaces in the SSH public key file.
