Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty who configure a custom user  *
    *                  registry and use certificate login          *
    ****************************************************************
    * PROBLEM DESCRIPTION: User registry error after               *
    *                      mapCertificate call                     *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When certificate login takes place, Liberty calls the
    mapCertificate() method on the custom user registry to map the
    incoming certificate to a user.    Somehow,  Liberty incorrectly
    thinks the return value of mapCertificate() is uniqueUserId
    where it is actually securityName.   Liberty then calls
    getUserSecurityName with securityName as an input.   This is
    unexpected input for custom user registry and it could throw an
    error.    The error stack varies but it is after mapCertificate
    is called and from user registry code due to incorrect input
    value from Liberty one example of an error seen is shown below.
