MIT X11R3, VAX 4.3 BSD, NCD16 terminal:

When using xdm, my group permissions as reported by groups(1)
are not set correctly.  I have done some debugging and have found
that the groups are correct in XDM after the setgroups() call
(determined by getgroups). After the execve of 
"/usr/local/lib/xdm/Xsession" the group permissions are incorrect.
I though that group permissions are inherited across an exec.
Has anyone else seen this behavior?  Xdm is running at root.
Also, Xsession is executable and is as follows:

#!/bin/ksh
#
# Xsession
#
# This is the program that is run as the client
# for the display manager.  This example is
# quite friendly as it attempts to run a per-user
# .xsession file instead of forcing a particular
# session layout
#

#
# KornShell /etc/profile.  This file is executed first for every
# xdm login session, 
#

export	PATH=/usr/local/bin:/usr/local/bin/X11:/usr/hsi/bin:/usr/ucb:/bin:/usr/bin 

if [ -f $HOME/.xsession ]; then
	exec $HOME/.xsession
else
	uwm &
	exec xterm -fn 10x20 -geometry 80x24+20+20 -ls
fi

Any help would be appreciated.
