Hi Christopher, I may use your first link as a possible workaround, but just to reiterate I am not trying to login to GNOME using root. I am trying to give my standard account "user" the ability to edit the settings within GNOME Control Center and elsewhere within GDM. On my Ubuntu system, the Authentication window will pop up (i.e. when accessing GParted) and my user account password will allow access. I assume this is because said user is part of the "sudo" group. Furthermore, my user account is listed as "Administrator" in GNOME Control Center and I am able to click the "unlock" button to make changes to user accounts (i.e. change an account from "Standard" to "Administrator). I never had to manually change this user in GNOME from standard to admin because it was already Adminstrator from the get-go. In contrast, my LFS system has root login disabled by default (as it should for security reasons), and I can login no problem using my "user" standard account I created during the build. This user is added to the "wheel" group and the Sudo package is installed to allow root access through the wheel group. Furthermore, I can run commands in the terminal application using "sudo" with my regular user. However, I cannot change any settings in GNOME Control Center (such as editing user accounts) by clicking the "unlock" button or open certain programs because the popup Authentication window in GDM refuses my user's password and the root account password. I understand why root's password wouldn't work seeing as I have disabled root login. And I assume that I cannot enter my user password in the Authentication window because the user account is listed as "Standard" in GNOME Control Center instead of "Administrator." So I am trying to figure out how to set the necessary permissions so that my created user account is able to authenticate in the popup window in GNOME since apparently being in the "wheel" group is not enough besides having to allow root login in GNOME just to change the user account from "Standard" to "Administrator" in GNOME Control Center. It seems likely that I missed a step or made an error possibly when setting up PAM with GDM or something, but I am not sure what that would be. Thanks, Jared Stevens
