Ah, but it does, right? Is that not the whole point of the topic?

If I say LOGIN FOO I can tell right away that FOO is an invalid userid (from 
the appearance of the login screen). There is nothing to stop me from trying 
every possible userid from $ to Z9999999 in an automated fashion to enumerate 
the userid's of the LPAR (other than time, there being around 5 * 10^11 of 
them).

Review your solicitor to eliminate this pain.

As Boris Lenz kindly suggested, use PA1.

You will see LOGON on a clean 3270 screen, just retype LOGON followed 
optionally by your right id and you're in.
If you don't use id after LOGON, you get that familiar IKJ message as usual 
which is waiting for your input.

I believe this is WAD. RACF won't tell you via TSO/SSHD *why* your logon is 
rejected, it simply says your attempt is invalid.

That topic of not telling the reason of failed logon was covered in RACF-L in 
the past.
