OK - so now you've setup your Live Communications Server environment and login to Office Communicator 2005 or Windows Messenger just to see an empty list of users. Then the next questions come into mind - how do you populate users?
In Inceptio we initially used dsquery and some of the scripts that are part of the LCS 2005 SP1 Resource Kit.
First of I used dsquery to create a file with contacts (Check dsquery /? for further commands e.g. for traversing more OU's)
dsquery * "OU=Users,OU=Inceptio,DC=domain,DC=com" -attr msRTCSIP-PrimaryUserAddress -filter (msRTCSIP-UserEnabled=TRUE) > contacts.txt
Then I used the LCSAddcontacts.wsf script that will add contacts to a list of LCS users (The contacts.txt created earlier) - the script can be found in "%Programfiles%\Microsoft LC 2005\ResKit\WMI Samples" and information on the use can be found in LCSAddcontacts_readme.htm file
CScript LCSAddContacts.wsf /usersfile:contacts.txt /contactsfile:contacts.txt /contactsgroup:Inceptio
As you can se I use the same file twice for both the user and contact list, thereby adding all users to all users contacts list (Thanks to Ray Breen / Google for this trick).
Then I need to auto allow the users. This is (in my case) easily done by using LCSAddACEs.wsf (Also from the reskit)
CScript LCSAddACEs.wsf /usersfile:contacts.txt /acesfile:Acesfile.txt
I reuse the same contacts.txt file used earlier, but I now use also use an Acesfile.txt file containing the following text (Notice that Allow, Prompt, Block and Deny are case sensitive) -
domain inceptio.dk Allow Allow
As we are a small consulting company there is no problem in auto allowing all users to see each other, I recognize that this will not be useful in most larger companies (Certainly not in our customers), in these cases I would manipulate the contacts.txt file to create a new file looking like this -
user: sip:firstname.lastname@example.org Allow Allow
user: sip:email@example.com Allow Allow
I would not recommend using All Allow Allow as acesfile.txt input as it also gives All Other Contacts allow rights (Instead of notifying as usual), which probably isn't a desirable behavior for PIC or Federation contacts.
The above is just an example of how to use the sample scripts to populate users. It would be a good idea to join and refine the scripts into a single script taking e.g. OU or AD Group as input and then populating organization groups etc. with each other contacts.
Btw. the above scripts should be run from the LCS Home Server
