>Description:

If you use xdms XDCMP responses usually contain the load and number of
users of the box.

This is done via the line:

DisplayManager.willing:  su nobody -c /usr/X11R6/lib/X11/xdm/Xwilling

in /usr/X11R6/lib/X11/xdm/xdm-config

This fails with 'This account is currently not available'.

While searching for this problem I found it is also an OpenBSD PR
(system/2145)

>How-To-Repeat:

ice:~#su nobody -c /usr/X11R6/lib/X11/xdm/Xwilling
This account is currently not available.

To see this problem in action, modify /usr/X11R6/lib/X11/xdm/Xaccess
to allow XDCMP indirect/direct requests and start X with -indirect

>Fix:

Modify this line (add -m) to:

DisplayManager.willing:  su -m nobody -c /usr/X11R6/lib/X11/xdm/Xwilling

or give user nobody a shell (less recommended)
