>SELinux is preventing /usr/bin/xauth from link access on the file xauthority-c.
>
>*****  Plugin catchall (100. confidence) suggests  ***************************
>
>If you believe that xauth should be allowed link 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.
>Do
>allow this access for now by executing:
># grep xauth /var/log/audit/audit.log | audit2allow -M mypol
># semodule -i mypol.pp
>
