The optional ACF2 PROFILE CLIST was implemented. Users at TSO logon get error message ACF6C004 LOGONID xxxxxxxx CHANGED every time now.
Release : 16.0
Component : CA ACF2 for z/OS
The TSO profile command permits users to update the the users TSO session attributes both in-core and in UADS so that the updates affect both current and future sessions. If the PROFILE clist is a logon clist, this will change the logonid record EVERY time a logon to TSO is done, even if the data does not need to be changed.
