Hi there!

You can find information about the format of this file in the man page for
xauth(1). You have to be carefully when setting up a network-wide xdm-directory!
xdm tries to write this file, so the server can read it and set up the
auth-records to check the authorization of the user!

A hack we use here locally - which is kind of a compromise - is to use
various xdm-config files (xdm-config.<host1>, xdm-config.<host2>, etc.).
They all look similar, but have entries different entries for 
	DisplayManager.errorLogFile:
	DisplayManager.pidFile
	DisplayManager.remoteAuthDir
and
	DisplayManager.DISPLAY.authFile
This entries point to directories where xdm has write permission and names
that don't collide.

Xdm gets started from /etc/rc with
	xdm -config <xdm-directory>/xdm-config.<localhostname>
This works fine for us!

Hope that helps

P.S. We had problems on mVaxen that the DisplayManager.remoteAuthDir resource
     wasn't read correctly! Therefor we changed the local Imakefile and every-
     thing worked fine!
