I had a quick look at the code for xdm in NetBSD's XFree86 and Xorg's 
xdm.

Looks like I found the problem:

HAS_SETUSERCONTEXT is not defined.

A fix for HEAD (-current) and netbsd-4 exists:

http://cvsweb.netbsd.org/bsdweb.cgi/src/x11/bin/xdm/Makefile.xdm

If that solves your problem then we need to request a pullup. Please let 
me know.

If you are using Xorg from pkgsrc or using XFree86 from NetBSD HEAD then 
we will have to research it further.
