Summary:

SELinux is preventing the kdm from using potentially mislabeled files
(/root/.Xauthority-c).

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux has denied kdm access to potentially mislabeled file(s)
(/root/.Xauthority-c). This means that SELinux will not allow kdm to use these
files. It is common for users to edit files in their home directory or tmp
directories and then move (mv) them to system directories. The problem is that
the files end up with the wrong file context which confined applications are not
allowed to access.

Allowing Access:

If you want kdm to access this files, you need to relabel them using restorecon
-v '/root/.Xauthority-c'. You might want to relabel the entire directory using
restorecon -R -v '/root'.
