su from root to user

[w***@gmail.com]

we recently upgraded to Centos 4 and now for some reason when we try to
go from root to another user we get
{su - user
su: incorrect password}
In the past it has always done this automaticly. Has there been some
default change we don't know about or is the problem elsewhere.

Interesting - never seen that one before. As root (with root's
environment), do

strace -eopen su - user

and see where things are b0rked.

I had posted a similiar problem for my nis client not allowing
a nis user to use su. One suggestion I received was to use
the wheel group for users you want to have access to root
(su - root). I havent tried it yet but it may be worth trying.
