Turning on

Under Fedora Core 4, /etc/pam.d/system-auth says not to edit that file by hand because authconfig overwrites it. However, "man authconfig" doesn't say how to turn on, and neither does the authconfig GUI. Can you tell me how to turn the on? This is with regards to your article, "Account locking for Linux via PAM."

Sorry I should have addressed this as part of my tip. I am afraid there is no clean and easy way around this. I tend not to use the authconfig command (or the associated GUI) to configure systems. But if I have to run authconfig, I make copies of the system-auth file before running authconfig. That way I can add back in previous changes made to the file.

I also recommend the use of a central configuration manager like cfengine or puppet to keep files like this up to date from a central point.
