The CentOS server is running with SELinux in permissive mode.
I would prefer to run it in enforcing mode,
and to that end would like to solve the problem above.

No, CentOS-6.4 was recently installed,
and the system has always been in permissive mode.

This is the response to "yum install xauth":
Package 1:xorg-x11-xauth-1.0.2-7.1.el6.x86_64 already installed
and latest version

On the server
===================
[tim at grover ~]$ ls -lsZ .Xauthority
-rw-------. tim tim unconfined_u:object_r:xauth_home_t:s0 .Xauthority
===================
Same on the connecting laptop
===================
[tim at rose ~]$ ls -lsZ .Xauthority
-rw-------. tim tim unconfined_u:object_r:xauth_home_t:s0 .Xauthority
===================
Incidentally, if there was something wrong with .Xauthority
shouldn't sealert point this out?
