Summary: SELinux is preventing /usr/bin/xauth "write" access on .xauth7rfxHb. Detailed Description: SELinux denied access requested by xauth. It is not expected that this access is required by xauth and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug report.

Please run restorecon -R -v /root And see if this happens again. I think this is just a mislabling that was fixed with the -32 package and once your labeling is correct, will not happen again. If it does happen again please reopen the bugzilla.

Created attachment 366528 [details] audit.log I wanted to open this back up quick. Feel free to close it again if appropriate. I noticed that I get a lot of these kind of messages when I use su - or su -c. Everything seems to work fine, so I guess there's no harm, but perhaps these warnings shouldn't be happening if su - or su -c is expected to work fine.
