Display revoked users?

Hello,

Is there a way on unix to see if a userid is suspended or revoked? I have an I.D but when I try to use it it keeps saying Sorry!

Which UNIX derivate?
Normally you see this in /etc/shadow, but there are more userfriendly commands.

I'm using AIX 5.1

$ lsuser 

look at the flag "account_locked"
