I am now able to refine the last pending question of my V5.0 vs V3.2 bunch.

I remember I did some changes on MY 3.2. with xdm systems namely
- ptys in /etc/securettys
- adding me to the system group
- listing the machine name in /etc/X0.hosts
- changes in /var/X11/xdm namely
- in xdm-config set DisplayManager._0.authorize to false
(also set DisplayManager._0.terminateServert to true)
- in Xresources (changes of colours, font, greeting text)
- in Xsetup_0 (also changes of look of login screen)

The only hint I had was from Nikola Milutinovic :

DISPLAY is set to :0.0 when logged in as user, and is inherited as such when
su'ed to root. This is the same which happens also on my 3.2 system.
I suspect the trick on my xdm system was the authorize bit in
/var/X11/xdm/xdm-config. Essentially this disables the .Xauthority stuff and
uses xhost stuff instead.
At the time, I managed to customize my 3.2 systems using the following
documentation part of my DU 3.2 kit : the O'Reilly volume 8 "X Window System
Administrators Guide" and its DU 3.2 supplement X Window System Environment
(part AA-Q7RNA_TE).
I also have some Sun CDE manuals (but on our Suns nobody ever managed to
disable the need to do xhost before su).
Now my questions are :
- what is the way to do the authorize trick under CDE ?
- what are the right documents for CDE system configuration
under Tru64 5.0 ? Are they available on-line ? If not what are
their part numbers so that we could order them ?
- are the release notes for upgrade from 3.2 to 4.x to 5.0 available
on line or elsewhere ? I have always been a keen reader of such stuff
(read and be suspicious before you upgrade), but in this case we got
a system from outside and without updated doc.
