Get the user to login on a machine you control and which has debugging
tools.  Examine the list of cm_user_t objects and walk the list until
you find the one for the user.  Examine the ticket in memory.  Is it
corrupted there?

If not, perhaps you have found another instance of the bug which is
causing AIX to fail.
