Workflow?
Not sure what you mean. We want to restrict access to the DTUs.
Simple as that. This is a large telescope perched on top of a mountain
in Chile and we don't want everyone to access everything. I'd also
like to keep everything locked and cooled inside the computer room,
with one card reader, one kbd, one mouse and two screens (maybe 10
though) in the front control panel (a purpose built unit that almost
resembles NASA mission control but doesn't nearly as cool).
For the timebeing we're just testing Sun Ray out to see if it'll work
here, and that the users will actually like it.
If one DTU is the primary, how do I specify which DTU is the primary,
or does SRSS do this?
Is there any way to predict which DTU SRSS decides will be the primary,
especially during the configuration?
The -p option specifies the primary. For example...
#> utmhadm -a mh_group -g 2x1 -l 12345678abcd,12345678abce -p
12345678abcd
will give you a multihead group named "mh_group" with a 2 column by 1
row screen consisting of two DTU's whose MAC addresses are 12345678abcd
and 12345678abce where the DTU with MAC address 12345678abcd is the
primary DTU.
If you are looking to restrict physical access to the DTU's, placing
them inside the locked server room is the way to go.
If you are looking to restrict soft/login access to the DTU's, I would:
1. Disable non-card logins
2. require that all cards be registered
3. disable self-registration
4. as the administrator, register and hand out cards to those who need
to log on to the system.
5. users will still need to use their username and password.

you're trying to do, but it doesn't make sense to me.
Multi-Head Sun Ray's are typically located in the same physical
workspace so that on user (identified by card or pseudo token) can have
both displays tied to their single session. Most of the time they have
Xinerama turned on so that they have one large desktop spread between
the two screens.
In a MH setup one DTU is the primary and the other is the secondary.
The kbd and mouse should be connected to the primary. The primary is
also where the card would be inserted and removed for session mobility.
The dtlogin window should show on the primary DHU in the MH group.
What work flow are you trying to accomplish with two DTU's in separate
locations as part of the *same* Mh group?

_Update: _
With the card in DTUB (has kbd and mouse in it), the dtlogin is
displayed on DTUA and the kbd and mouse on DTUB don't work.
If I remove the card and insert it into DTUA, the dtlogin moves to DTUB
and the mouse pointer can be moved, but cannot interact with dtlogin.
The kbd does nothing.
With no card inserted the dtlogin moves to DTUA, and the keyboard and
mouse on DTUB don't work.
NB. Keyboard and mouse are Dell and Logitech, but the initual multihead
config was done with the same keyboard and mouse, which worked then.

I have tried to setup a 2x1 multihead policy for two DTUs. However, one
DTU is inaccessable by users because it is in the conputer room, and
the other is accessable by users in the operations room. One keyboard
and mouse plugged into the DTU in the Operations Room. We only want
the users to use one smartcard reader. I thought that this would be a
simple task, but my three attempts have simply driven me crazy. Have
anybody got any ideas on why it is impossible to assign keytboard
control between the two DTUs.
NS. There is only one keyboard and mouse for the two DTUs.
*Attempt 1*
Set up two DTUs in a 2x1 multihead policy. [DTUA and DTUB]
Started utumhconfig on DTUA and set policy up. DTUA is on
righthandside.
Moved smartcard to DTUB. DTUB is on lefthandside.
Removed smartcard and put into DTUA.
Keyboard and mouse are then plugged into DTUA.
Results: utmhconfig automatically put keyboard control on lefthandside
(DTUB). This is not what we want because DTUA is in the conputer room
and DTUB is in the users' Operational Centre.
*Attempt 2*
Set up two DTUs in a 2x1 multihead policy. [DTUA and DTUB]
Started utumhconfig on DTUB and set policy up. DTUB is set to
lefthandside.
Moved smartcard to DTUA. DTUA is set to righthandside.
Smartcard is already in DTUA so don't have to move it.
Keyboard and mouse are already plugged into DTUA.
Results: utmhconfig automatically put keyboard control on
lefthandside!
This is not what we want because DTUA is in the conputer room and DTUB
is in the users' Operational Centre.
*Attempt 3*
Physically swapped DTUAs position with DTUB.
Plugged keyboard into DTU in the operations centre.
Results: The keyboard and mouse control have magically moved to the
opposite DTU!!!! WTF. I physically moved the DTUs from one room to
another. How is this possible?
I tried attempt 3 again, incase I had mixed up the two DTUs when I
pshyically swapped their positions, but got the same results!
