Setting up Sametime® and iNotes® in different domains

You can set up a cross-domain configuration when the IBM® Sametime® server and the IBM® iNotes® server are located in different domains.


  1. Cross certify both domains with each other. This step is necessary only if the Sametime® server uses IBM® Domino® authentication instead of LDAP.
  2. Configure directory assistance on the Sametime® server as needed:
    • If Sametime® uses native Domino® authentication, then directory assistance must point to the iNotes® server, using the IBM® Notes® protocol instead of LDAP.
    • If Sametime® was installed to use LDAP, then directory assistance is configured automatically, and nothing further is necessary.
  3. If you have set up single sign on (SSO), go to Step 4. If you do not have SSO set up, replicate STAuthS.nsf to the iNotes® server. The file name is case sensitive on Unix servers.
  4. Create a server document for the Sametime® server in the Domino® Directory of the iNotes® server, completing the following fields:
    • Server name
    • Domain name
    • Fully qualified Internet host name
    • Is this a Sametime® server?
  5. Enter the Sametime® server name in the Sametime Server field of each iNotes® user's Person document.
    Note: You can specify the Sametime® server name in the server configuration document to globally set the Sametime® server for all users. Use the Set an IBM Sametime Server host name for all IBM iNotes users (useful for clustered configurations) field.
