The real fix for this issue, is to properly set the security context on
the /usr/sbin/gdm3 executable.

-rwxr-xr-x. 1 root root system_u:object_r:xdm_exec_t:s0 263592 oct 20 17:53 /usr/sbin/gdm3

You should check that you have at least the
package selinux-policy-default (2:2.20110726-11) installed and relabel
your filesystem (touch /.autorelabel && reboot).
