I am a newbie.. so I don't know "what I want to use" - I don't need any
kind of security at all. I just want to be able to logon to other
accounts... not only root.. When I installed the PC I don't recall any Q regarding the
authentication - and if there was - I probably said "don't care" - ad it
worked fine until I made the mistake and touched that tab (while trying
to solve other problem)
OK, in authconfig, leave all of the "user information" fields blank and select "Use MD5 passwords" and "Use shadow passwords" (and nothing else) for authentication.
Make sure that the accounts you are trying to log in to have entries in /etc/passwd and /etc/shadow.
What is the symptom you get when trying to log in as other accounts? Does it say "bad password" or something similar, or does it appear to log in and then log out again immediately?
I even would love to know how to make the PC boot automatically into an
account I set (not root) without asking me for user name and password..
Let's make sure that the other account works first.
Paul.
