SELinux is preventing /usr/bin/xdm from 'write' accesses on the file /var/log/xdm.log.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that xdm should be allowed write access on the xdm.log 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 xdm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
