Unable to connect to xserver with xdm 3.3.2.3a-11

[Scott Ingram <scott@silver.jhuapl.edu>]

Went ahead and used "apt-get dist-upgrade" to move
to the new 2.1 distribution and now I get the following
errors in the xdm-errors log:

AUDIT: Wed Mar 10 08:45:17 1999: 201 X: client 1 rejected from local host
  Auth name: MIT-MAGIC-COOKIE-1 ID: -1
Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
/usr/X11R6/bin/xsetroot:  unable to open display ':0'

Anybody else having a problem like this?
