SELinux is preventing /usr/bin/kdm from 'create' accesses on the file .Xauthority-c.

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

If you believe that kdm should be allowed create access on the .Xauthority-c 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:
# grep kdm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Do you log in via X as root?

Since SELinux does not support logging in as root, I am closing this bugzilla.
