Description of problem:
SELinux is preventing accounts-daemon from 'getattr' accesses on the file /var/lib/AccountsService/users/gdm.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label. 
/var/lib/AccountsService/users/gdm default label should be accountsd_var_lib_t.
Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case try to change the following command accordingly.
# /sbin/restorecon -v /var/lib/AccountsService/users/gdm

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that accounts-daemon should be allowed getattr access on the gdm file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'accounts-daemon' --raw | audit2allow -M my-accountsdaemon
# semodule -X 300 -i my-accountsdaemon.pp

It looks like the file in the setroubleshoot report has invalid label. The unlabeled_t label is usually displayed when a file was created in SELinux disabled state or when its actual label does not currently exist.

You can fix the label with the following command:

  # /sbin/restorecon -v /path/file

or setup the machine to relabel all filesystems on the next reboot:

  # fixfiles onboot

and reboot the system.

Closing as NOTABUG. Feel free to reopen the bugzilla if the issue persists.
