Lotus Sametime users with different 'home' servers cannot see each other online

I am new to Notes/Domino and Lotus Sametime. I noticed that users with different "home" Sametime servers cannot see each other online. I was trying to perhaps develop a plug-in that would provide this functionality. Is there a way to achieve this?
Lotus Sametime users within the same Lotus Domino domain (and even across different domains) can see one another, as long as their "home" servers are aware of the existence of other Lotus Sametime servers through a "Community."
To ensure that your servers are aware of one another, create Sametime connection documents in both directions (i.e. Server A -> Server B and Server B -> Server A) using the Domino administrator client.
To check whether your Lotus Sametime servers can see other members of the community:
  1. Open a Web browser, go to the Sametime Web Administration Utility (http://yourserver/stcentre.nsf and choose the "Administer the server" link).
  2. Expand the "Configuration" heading and then choose the "Connectivity" option.
  3. When the "Configuration - Connectivity" page opens, click the "servers in the Community" tab.
  4. If you see both Server A and Server B under the "Meeting Servers that are connected" section, your servers should be able to communicate with one another.
To create the Lotus Sametime connections:
  1. Start your Domino administrator client.
  2. Go to the Configurations Tab.
  3. Expand the server's Twistie and choose Connections.
  4. On the Action Bar, choose "Add Connection," make the connection type "SameTime," complete the Source (Server A) and Destination (Server B) server fields, and add an optional network address for the destination server.
  5. Now add another connection document going in the other direction.

Sametime connect list disappeared

Using a 6.5.1 client, and logging into Sametime, the connect list has "disappeared." It will not show up on the client. However, if you use the Sametime connect client, the connect list will show up there. We are operating on XP.
I have seen this occurring when the Sametime server utilizes LDAP authentication, rather than Domino authentication to log-in.
If you are using this configuration, change the connection settings in your location document from "Automatically" to "Manual," disconnect from the Sametime session and try to log in again. In the username and password window, try either your short name (as specified in the Domino Directory) or your e-mail address, in conjunction with your Internet password.
As an example, rather than logging onto Sametime through Notes as "Mathew Newman/iteam," try either "mnewman" or "mnewman@iteam.com."

How to enable communication between multiple Lotus Sametime servers

In our Notes/Domino organization, we have set up a primary and secondary Lotus Sametime server. The primary server is a Notes/Domino server and is set as a standalone machine. The second server is on a separate Notes/Domino server, and was set as a member of the primary server at the time of installation.
Clients of the primary Lotus Sametime server are only able to communicate with members of the primary server. Clients of the secondary server are only able to communicate with members of the secondary server.
We would like to enable communication between multiple Lotus Sametime servers. For instance, we'd like a member of the primary server to be able to send messages to a member of the secondary server. We were not able to add users from the primary server to the secondary server or vice versa.
How can we add members of the secondary server into the contact list of members of the primary server?
The easiest way to confirm that your Lotus Sametime servers are members of the same community is to check the "Community" settings in the Lotus Sametime Web administration client.
  1. Open a Web browser, go to the Sametime Web Administration Utility (http://yourserver/stcenter.nsf and choose the "Administer the server" link), expand the "Configuration" heading and then choose the "Connectivity" option.
  2. When the "Configuration - Connectivity" page opens, click the "servers in this community" tab.
  3. If you see both the primary server and secondary server under the "Meeting Servers that are connected" section, your Lotus Sametime servers should be able to communicate with one another.
I'm going to go out on a limb here, and suggest that you will not see both servers in this section. From the description of your setup, I'm guessing that your infrastructure is that your primary server is on one machine and your secondary server is on a separate machine.
But from what you have indicated, both servers are members of the same Lotus Domino domain ("member of the primary Sametime server at the time of installation"). This means that the servers already "trust" one another -- being members of the same organization. They are therefore able to see all servers and users within the domain, because the Sametime servers share the same Domino directory.
Side Note:
Domino domain is a collection of servers and users who share the SAME Domino directory (names.nsf/ Public Address Book, etc). An organization is a security mechanism for creating and identifying entities (servers/users) within the Lotus Domino domain.
If both servers are members of the same Domino domain, then you simply need to create a Sametime connection document in your Domino directory, similar in the way to creating a replication connection document.
  1. In your Domino Administrator client, go to the configurations tab, expand the Server's Twistie and then choose "Connections."
  2. On the Action Bar, choose "Add Connection", make the connection type "Sametime", complete the Source (Primary server) and Destination (Secondary server) server fields and add an optional network address for the destination server.
  3. Add another connection document going in the other direction.
Give your system a little while to detect the new configuration, and you should see both Lotus Sametime servers listed as "Connected."
If your servers are not part of the same Lotus Domino domain, then you will need to do a little more work:
  1. Cross certify the two servers , so that the servers trust one another.
  2. Configure Directory Assistance on both Lotus Sametime servers, so the servers can access one another's directories.
  3. Create the Lotus Sametime connection documents described above, so the Lotus Sametime servers can communicate.

Enabling a Domino server to host Sametime applications

From "The ABCs of enabling Notes and Domino applications with Sametime," by John Fiola, consultant, Lotus, which originally appeared in the Sept./Oct. edition of The View.
If you choose to host Sametime-enabled Notes applications from a Sametime server, no special server setup is required. The Sametime server can be installed on Windows NT.
If you want to serve Sametime-enabled applications from a Domino server, you will have to do the following:
1. Install the Sametime server. When you install the Sametime server, three databases are created that are used for deploying Sametime applications: the Secrets database (StAuthS.nsf), the Tokens database (StAuthT.nsf) and the VPUserInfo database (VPUserInfo.nsf).
The Tokens and Secrets databases handle authentication and log in to the Sametime servers for the users of a Sametime-enabled application.
The VPUserInfo database stores information used to restrict whom a user can see or who can see the user. This information is configured with the Connect client. Restrictions apply to both the Connect client and to applications through which the user may connect.
2. Replicate databases to the Domino application server. The Secrets database and the Tokens database must be replicated from the Sametime server onto the data directory of the Domino server, maintaining the same file names as on the Sametime server.
Unlike the Secrets database, the Tokens database doesn't have to be regularly replicated to the application server, but it is recommended that you replicate it at least once. The file names must be maintained because the Sametime agents have these file names hard-coded into them.
The VPUserInfo database does not need to be replicated onto the Domino application server. Access restrictions will be checked when the user logs in to the Sametime server.
Once a Domino application server is Sametime-enabled with the Tokens and Secrets databases, it can host multiple Sametime-enabled databases. You do not need to put new replicas of the Tokens and Secrets databases onto the application server each time you create a new database.
