Re: [foxboro] X-window login environments

Brad,
   If you created separate display menus structures for each of the 
environments, then each environment would only have access to those 
displays that you place in the menu structure.

This should be an easy question for the many knowledgable X-windows users
on this list.
We have an ancient system - AW51B, v4.3 - and are just starting up our
first X-windows station (to replace a PW-OE). I have it up and running on 
a
PC with Windows 98 and Exceed. Now I need to set up security.

The host AW51B serves as the operator station in one process area and the
X-station is the operator console in another area. I would like the
operators in area A to only be able to see graphics in area A, and B
operators only see area B graphics. I have created separate environments
for the two areas, but I don't want to use passwords to prevent access to
the environments (because we could never keep the passwords secure). Is
there a way to have the X-station boot up automatically into an 
environment
which the host AW is not able to change to? Or do I need to use the same
environment for both areas and disable the graphics that are not needed?
Ideally, I would like to have the PC power up directly into an Exceed
session logged into the area B environment with no way for the operator to
back out to Windows. Eventually, we will have 2 more of these X-stations 
as
we replace our other PW-OEs.
