Hi,
I have a strange su hehavior on a CentOS 5.4 32Bit installation in a
VMware ESXi virtualizied environment:
If I am root and want to change the user to a non-root user, the system
prompts me for a password:
[root at halifax ~]# useradd test00
[root at halifax ~]# su - test00
We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
Password:
[test00 at halifax ~]$ logout
[root at halifax ~]# su - test00
[test00 at halifax ~]$ logout
[root at halifax ~]#
At this test procedure I just hit the enter key at the password promt.
Do you have any idea for this behavoir? I expect to do so from root to
any account _without_ being prompted for the password.
Thanks,
Uwe

Figure out why you're running sudo and not su as you expect. Is it aliased? -- Don Krause "This message represents the official view of the voices in my head."
