Yes.

The XDM code as distributed from MIT for System V based machines, creates
the socket for listening to XDMCP requests, but then ignores the socket
completely.

If you have the X11R4 source tree, then you can kludge a solution which
enables the XDMCP support, but at the expense of disabling support for
terminals in the /usr/lib/X11/xdm/Xservers file.

The real fix for System V machines requires a large re-write, because the
xdm program relies heavily on BSD signal semantics.

I have reported this bug to SGI, but haven't heard back from my contacts
there. If you have source and want my patches, send me mail!
