Summary:

SELinux is preventing polkit-read-aut (polkit_auth_t) "write" to
/var/log/gdm/:0-greeter.log (xserver_log_t).                    

Detailed Description:

SELinux denied access requested by polkit-read-aut. It is not expected that this
access is required by polkit-read-aut and this access may signal an intrusion   
attempt. It is also possible that the specific version or configuration of the  
application is causing it to require additional access.                         

Allowing Access:

Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for /var/log/gdm/:0-greeter.log,               

restorecon -v '/var/log/gdm/:0-greeter.log'

If this does not work, there is currently no automatic way to allow this access.
Instead, you can generate a local policy module to allow this access - see FAQ  
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable   
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.
