Note: If a graphical user interface is not installed, this requirement is Not Applicable.

Verify the SUSE operating system does not allow unattended or automatic logon via a graphical user interface.

Check that unattended or automatic login is disabled with the following commands:

> grep -i ^DISPLAYMANAGER_AUTOLOGIN /etc/sysconfig/displaymanager

DISPLAYMANAGER_AUTOLOGIN=""

> grep -i ^DISPLAYMANAGER_PASSWORD_LESS_LOGIN /etc/sysconfig/displaymanager

DISPLAYMANAGER_PASSWORD_LESS_LOGIN="no"

If the "DISPLAYMANAGER_AUTOLOGIN" parameter includes a username or the
"DISPLAYMANAGER_PASSWORD_LESS_LOGIN" parameter is not set to "no", this is a
finding.
