My exit point prohibits ODBC Logon for all users except those in a list.
Care to try again?

Subject: RE: Enable Disabled Users and Devices
I think it's great to disable user profiles upon bad signon's.
Users can't generate a list of users? True. But they can generate a list of user message queues. They have to be able to. If they don't have access to the message queues then they can't send them a message.
So you generate a list of message queues like this
WRKOBJ OBJ(QUSRSYS/*ALL) OBJTYPE(*MSGQ)
Oh? You secured them from the command line? Simple to work around. They can download any number of tools to do this:
from table(OBJECT_STATISTICS('QUSRSYS', '*MSGQ')) x;
Then you just try signing on each one of those until they are disabled.
Soon, you've disabled every user on the system.
Great denial of service attack.
