Check Text (C-235031r991591_chk)

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 the GUI. 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" If parameter is not set to "no", this is a finding.
