Bug 708710

SELinux is preventing /usr/sbin/lxdm-binary from 'read' accesses on the file .dmrc.

*****  Plugin file (36.8 confidence) suggests  *******************************

If you think this is caused by a badly mislabeled machine.
Then you need to fully relabel.
Do
touch /.autorelabel; reboot

If you want to allow lxdm-binary to have read access on the .dmrc file
Then you need to change the label on .dmrc
Do
# semanage fcontext -a -t FILE_TYPE '.dmrc'

If you believe that lxdm-binary should be allowed read access on the .dmrc file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep lxdm-binary /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
