Fedora Root Login Activation

Fedora uses pam module called pam_succeed_if.so for its authentication. This module is designed to succeed or fail authentication based on characteristics of the account of the authenticated user. Default configuration of this module blocks root login using GUI.

STEP 1: Login as a Normal User.

STEP 2: Open the terminal and use your favourite text editor like vim or gedit to open the /etc/pam.d/gdm.

# su -c “vim /etc/pam.d/gdm”

STEP 3: Comment the following line ‘auth required pam_succeed_if.so user !=root quiet’

# auth required pam_succeed_if.so user != root quiet

STEP 4: Also open /etc/pam.d/gdm-password and put comment in front of the below line:

# auth required pam_succeed_if.so user != root quiet

Save the file and logout from GUI. Now you can login as root
