XDMCP setup (only one time)
I tried to connect to a Solaris computer through XDMCP (through Xnest from an RHEL 4u4 computer), but it doesn't quite work. I can login once and everything works perfectly. If I log off and try a 2nd time, I can see the login screen, and can enter the username and password, and then if they are correct, it automatically logs off. The only way to get it to work again that I can find is to reboot.

To get to this point, I reformated the computer with Solaris 6/6. After reformatting I updated /etc/ssh/sshd_config to change a line to
PermitRootLogin yes
and updated /etc/default/login file to comment out the CONSOLE=/dev/console line.

After that I edited /etc/X11/gdm/gdm.conf to enable xdmcp and set all the security settings to permit root logins and remote logins.

By the way, everything works when you log into a Linux node every time.
