Summary: SELinux is preventing /usr/bin/xauth "read" access on @sys. Detailed Description: [SELinux is in permissive mode. This access was not denied.] 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://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug report.

Miroslav add fs_read_nfs_symlinks(xauth_t) This looks like you have some kind of strange homedir setup. What is @sys?
@sys is an AFS shortcut for the current system's OS and architecture. i.e. On my system @sys expands to amd64_linux26. It could also be: i386_linux26 or i386_w2k
Thanks. So Miroslav, we definitely need the fix.
