Folks,
With the new SELinux updates, it appears that root, other than normal users can login to Fedora via VNC Server? My VNC Server is setup such that I am using xinitd for VNC Server requests.
A problem I noticed on FC4 with updates is that running VNC from initscripts will cause user sessions to have a system_u:system_r:initrc_t context. If you start a VNC server as the user from a shell, you get get the expected behavior of unconfined_t session.
Another problem I noticed is that when I log into my Fedora system via VNC as root user, and open a xterm window and run a su - <normal-user>, I get back a SElinux message:
================================================ # su - dan Your default context is: user_u:system_r:kernel_t.
Do you want to want to choose a different one? [n]

To get vncserver working properly on Rawhide, you can change the context to unconfined_exec_t
chcon -t unconfined_exec_t /usr/bin/vncserver
