[rhn-users] Authconfig Problem

Wed Sep 28 07:55:40 UTC 2005

Hi Sudhanshu,

Yes you are right. I added an abnormal word (my name)
to /etc/pam.d/system-auth file. Then I executed the
authconfig command as you described. My name was not
here. OK.

But there is another thing you should consider.This is
normal behavior of the system authentication
mechanism. You cannot change /etc/pam.d/system-auth
file abnormally. There are a lot of rules to edit the
system-auth file. 
So, you should decide to edit system-auth file
correctly to serve as you want.

Regards
