Disablin login for system accounts
Hy everyone!
I'm trying to lock out system accounts on my Tru64 UNIX machines.
Wherever I look, it says only to put Nologin or *Nologin in password field of desired account in /etc/passwd.
But it doesn't work. I still
can su to that accounts. There are some accounts that already have Nologin in their password field and to that account I
cannot su.
What am I doing wrong?
Do I have to do something else besides adding Nologin in /etc/paswd?
I used vipw for editing passwd file, in case someone asks
