SELinux is preventing /usr/bin/xauth from 'write' accesses on the directory auth-for-demus-Tt0K7y.

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

If you believe that xauth should be allowed write access on the auth-for-demus-Tt0K7y directory 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
