Bug#263449: kdm remote login fails

[Mark Small <msmall@eastlink.ca>]

Package: kdm
Version: 4:3.2.2-1
Severity: normal

I have several computers running debian testing.  I am trying to get
kdm's remote login to work using xdmcp.  I have set [Xdmcp] enable=true
on /etc/kde3/kdm/kdmrc.  In /etc/kde3/kdm/Xaccess, I have

*                                       #any host can get a login window
*               CHOOSER BROADCAST       #any indirect host can get a chooser

I've tried to connect 3 ways using xdmcp.

(1) Using kdm remote login:
When I ask for a remote login in kdm, I get a nice chooser window with a
list of computers.  But when I try to select one, X restarts TWICE and
brings me back to my local kdm login.  I also get this error in
/var/log/kdm.log

Fatal server error:
XDMCP fatal error: Session declined No valid address

(2) direct query from command line:
If I run 
X -query foo
I get a remote kdm login windows on another computer (foo).  I can login and
everything works perfectly.

(3) indirect query from command line
If I run
X -indirect foo
I get a chooser which I think is being provided by computer foo.  When I
select a computer from the list, X restarts ONCE, and then I get a nice
login window on whichever computer I want.  I can login and everything
works perfectly.

So it seems that there is something wrong with the way that kdm is
envoked, and that whatever is causing the problem is local.  I'm sure
that the double restart of X is a big clue, but I don't know what is
happening.
