Please use /usr/bin/authconfig-tui as you are in the single user mode, your environments are not set.

/usr/bin/authconfig-tui does not exist in my /usr/bin

There are only authconfig, authconfig-gts and authconf files in there.

"authconfig" will do just fine. Check "man 8 authconfig" or authconfig(8) - Linux man page for details. This will reset things and should correct if any unwanted change is causing this.

I tried authconfig --restorelastbackup but I am still not able to login.

Boot the machine into runlevel 3 and check if you are able to do console login or while on the graphical login screen, press ALT+F2 or ALT+F3 etc. to login to one of the virtual consoles. Check if you are able to do so.

I am not able to login in one of the virtual consoles. It gives me a "Login Incorrect" message for fraction of second and then it again asks me for a username.

This confirms the issue is with PAM. Is SELinux set to enforcing? Are there any AVC denial messages? To check this run the below commands:
Code:
getenforce

Code:
sealert –a /var/log/audit/audit.log
