Disabling the RedHat Enterprise Linux GUI login page from displaying the user list

About this task

If you have installed a graphical interface for RHEL, the RHEL GUI login page displays a list of users on the startup screen.

This list also includes the avayavp user. To eliminate a potential security hazard, you must disable the RHEL GUI login page from displaying the list of users.

Procedure

To disable the login page from displaying the list of users, enter the following command on the console:

sudo -u gdm gconftool-2 --type bool --set /apps/gdm/simple-greeter/disable_user_list true
To verify that the user list is disabled on the login page, enter the following command on the console:

sudo -u gdm gconftool-2 --get /apps/gdm/simple-greeter/disable_user_list

If the command returns the value as True, then the login page does not display the list of users.
