We have the same problem with Xterminals from Sun (X Term classic) 
with xdm X11R6 on an Sparc 20 running with sunos 4.1.3U_1, if i then look
at the networkmonitor i see very much traffic between the xterminal and
the server. (20% Networktraffic with not very much datatransfer(small pakets)).

But on our old Sun 3/80 running suos 4.1.1 which start at the end of the
rc.local an X11R5 (MIT) Server with 
"X -fp ... -query server"
we have no problems like the sun terminal. I often use some RS6000 (with 8MB ram)
as X terminal to our sun cluster. (X11R5 from IBM) and have only sometimes
problems with hanging xdm, if i kill the X server on the RS6000 in a session.
(startup >exec X -query server). So only our X Terminal from Sun makes problems
with the xdm X11R6.

I should know the answer to this problem; but I never wrote it down and now
I forgot :(    At one time, I thought it was a problem with scologin, and
recommended to those affected to try stock MIT xdm (which we use here anyway,
ripped from a previous version of ODT).

For now, check to make sure that you are NOT listing the Xterminals in
some kind of Xservers file on the host (typically /usr/lib/X11/xdm/Xservers,
but is something else in sco using scologin).  XDMCP replaces the Xservers
file, which is long obsolete (for everything except starting XDM on
the console Xserver).

We have been running several Xterminals on our network for quite some time
now, and have never had XDM hang or otherwise cause any problems.  (ODT2.0)

I am pulling my hair out on this problem. with the scologin on our development
system it never locks up. BUt on the product it does.

There are no entries in the Xserver file, so thats not the problem. With
Xconfig: DisplayManager*debugLevel:          1
set up is applears to hang during the password verification. Here is the log:

any help would be much appreciated, esp. what is it doing here?
Trying to verify the login and failing???
