I'm unable to login to Redhat 9.0 as a user, however I can su to a user and am still able to login as root. Here are a few things I've done recently that may have screwed things up, I've edited /etc/inittab, /etc/shadow, /etc/passwd and failed at installing apt and mplayer. I had problems with pam and compiling glut apps, however to fix it I had to change the permissions of a few files (mainly nvidia). Here are my errors (from /var/log/messages:
Feb 8 10:53:38 localhost login(pam_unix): authentication failure; logname= uid=0 euid=0 tty=tty1 ruser= rhost= user=drdroid
Feb 8 10:53:40 localhost login: FAILED LOGIN 1 FROM (null) FOR drdroid, Authentication failure
Feb 8 10:53:47 localhost login: FAILED LOGIN 2 FROM (null) FOR drdroid, Authentication failure
I heard somewhere that this might be releasing too much information, if it is, please just make a note of that in your responce. I really want my system back, I've been without for almost two days now.
