Description Jim Tyler 2014-02-28 03:12:52 UTC
Description of problem:
I just loged on to the computer and let it sit.
SELinux is preventing /usr/libexec/gdm-session-worker from using the 'net_admin' capabilities.

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

If you believe that gdm-session-worker should have the net_admin capability 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 gdm-session-wor /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
