thanks heaps - that little command is great to know,
only problem is i can’t login…not through virtual consoles or graphical login. I found someone else who posted the defaults and so I booted off system rescue cd to copy the files back over the old ones and found that they are actually symlinks (that is common-auth) etc etc to the file common-auth-pc. Neway I tried that but it didn’t work either, not sure what else I screwed up but I just reinstalled, have a separate /home partition so it’s no biggy =)
You could also have booted up the rescue system on the SUSE DVD and reinstalled the stock pam package (after mounting the root partition). Something to remember for next time.
