XDMCP and Solaris

[Mr. Andrew Ross MacKenzie]

I am looking to replace Exceed with XFree86 (hopefully) at my work, but 
have run into a problem in that XFree86 doesn't seem to work with a
Solaris machine (SunOS 5.7) running dtlogin as an XDMCP server.  We have
'non-technical' people who would be using this, so XDMCP is sort of a
pre-requisite (must be easy to use).

The error I get is along the lines of :
"cannot connect to <machine>:0.0"

Where <machine> is the name of my local computer (not the Solaris 
Machine).  This seems to be some sort of authentication problem.  But I
don't know enough about X to say for certain.

I'm sorry if this has been discussed before (I'm new to the list), but I
couldn't find any info about whether there is a way around this problem,
or if a fix is in the works.  

Thanks for any info.
