Re: [gdm-list] XDMCP proxy server with Xdmc

[Brian Cameron <Brian Cameron Sun COM>]

Peter:

The Xdmx feature in GDM is, as noted, experimental.  The fact that your
email hasn't generated any responses may be because you may be the first
to really try and use it.

If you find ways to improve the GDM code when working with Xdmx, please
let us know and I'll be happy to help you work through fixing any bugs
on the GDM side of things.  If you develop any patches to make the GDM
Xdmx code more robust, please share them and we can get fixes integrated
in the latest GDM releases.

I wish you the best of luck!

Brian
