| This requirement assumes the use of the OL 9 default graphical user interface—the GNOME desktop environment. If the system does not have any graphical user interface installed, this requirement is Not Applicable. Verify that OL 9 does not allow an unattended or automatic logon to the system via a graphical user interface. Check for the value of the "AutomaticLoginEnable" in the "/etc/gdm/custom.conf" file with the following command: $ grep -i automaticlogin /etc/gdm/custom.conf [daemon] AutomaticLoginEnable=false If the value of "AutomaticLoginEnable" is not set to "false", this is a finding. |
| Fix Text (F-75648r1091784_fix) |
| Configure the GNOME desktop display manager to disable automatic login. Set AutomaticLoginEnable to false in the [daemon] section in /etc/gdm/custom.conf. For example: [daemon] AutomaticLoginEnable=false |
