Hi..
Boot in single user mode.
Check ur PAM modules and the configuratons.
Add the following entires in syslog to route all the logs to virtual console F10
*.* /dev/tty10
Reboot the machine. Now u can see all the logs in Alt F10.
Try login and see the logs in Alt F10. It may help u to find out the problem.
Try to use Tripware for integrity
