RE: User profile question -- MIDRANGE-L

Rob,

I am not arguing the point about non-limited capability users and the
signon screen.  I agree that a user who is LMTCPB(*NO) can modify the
default menu/program/library entries on the signon screen and bypass
your initial program security.  

The point I was trying to make is that even users who are LMTCPB(*YES)
or (*PARTIAL) can have very broad access to the system by signing on
through other methods such as ftp.  Even if you specify that user BUBBA
has either a nonexistent initial program, or an INLPGM(*NONE) and
INLMNU(*SIGNOFF), BUBBA can still log onto the system through any of the
other connection points that do not use the 5250 interactive signon
subsystem (ftp being the easiest one to test).

Another way to look at it (and I bet we can agree on this) is that the
INLPGM and INLMNU parameters on a user profile are convenience tools -
they help you customize the environment for the user - they are not
security tools because you cannot guaranty that a user with a valid
profile and password will invoke these parameters at every logon.
