That was quick!

You still did not answer my question about xdm-errors. Both xdm and the 
X server messages are directed there and are usually informative when a 
display connection is broken.

If xdm puts you back in the login prompt as soon as you logon, you are 
probably having a problem with the user or the server authorizations, 
not authentication. Try "xset +" and see if it complains or solves your 

If not, you can always use the debugger. You are, after all, in the 
driver's seat.
