X11 forwarding between from Mandrake(sshd) to Caldera(ssh) doesn't work!

[dgames at isoc.net]

I am having great difficulty getting X11 forwarding to work between
my openssh server (Linux Mandrake 6.1) and my openssh client (Caldera
OpenLinux 2.x).

I get "X11 connection rejected because of wrong authentication." on
the Caldera box when I ssh into the Mandrake box and try to run any X
app.

If I make the Caldera box the server all is fine and works perfectly.
 Terminal connections via ssh work great in both directions.

On both boxes I downloaded the sources for openssh 1.2.2 and openssl
0.9.4 compiled and installed with defaults.  I then enabled X11
forwarding in /etc/sshd/sshd_config and /etc/sshd/ssh_config.

Any help would be greatly appreciated.  I am not a member of this
list so CC's to <dgames at isoc.net> would also be very helpful.

Thanks in advance.
