Description Jóhann B. Guðmundsson 2011-03-31 12:37:54 UTC
SELinux is preventing /usr/bin/xauth from 'link' accesses on the file database-c.

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

If you believe that xauth should be allowed link access on the database-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
