su: incorrect password
[root@kickstart-server ~]#

[CODE]

are you saying that you cannot su, but need to be able to?
that users cannot login from remote locations but need to be able to?
as it is written, there is no question in your statements.

You are putting wrong password. Please verify the password from respective admin of that computer where you need to login.

You can change the password and try it again?
