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.

Problem conclusion

The code was fixed so that it will handle securityName and
uniqueUserId as expected.
