[Wlug] odd entry in /etc/passwd

So I just found an odd entry in /etc/passwd on one of my servers: +:::::: Of course I'm not running tripwire on it so I can't be assured of the last time I edited the file / did anything to edit it. etc/shadow doesn't have the entry but shadow is only checked if the second field is x, right? I'm running Suse and I've been using yast lately, could that have anything to do with it? I hope it does as I really hope I don't have to run a full audit on the box. tia -- Eric Martin
