Comment 1 Matěj Cepl 2008-10-15 04:43:06 EDT
Isn't this SELinux issue?

What is the output of the following commands?

grep xauth /var/log/audit/audit.log

Please attach the output instead  of pasting it here, if it is bigger.

THank you
Comment 2 Joe Smith 2008-10-15 10:01:40 EDT
Ack! No, not SELinux this time: idiot at the wheel.

/var was out of space; xauth is working fine now.

I'll go ahead and set this to CLOSED/WORKSFORME.

Sorry for the noise.
