Hide the Scalix Groups

[dougp23]

How do I hide the Scalix groups in the system address book?
My users keep asking what they are, and it would just be better if they were invisible.
If I login to SAC, and go to groups, the checkbox to not show them is grayed out.

The command I used was

ommodent -e S=<User or Group> -n EX-CDA-DIRECTORY=1

eg. ommodent -e S=sxadmin -n EX-CDA-DIRECTORY=1

I think I found this command on the forums somewhere. I am 99% sure this is correct, but please research some more before running the command.
