Configure single sign-on

How you configure single sign-on between WebSphere Portal and IBM Lotus Sametime depends on the directory that each server uses to authenticate.

If your environment does not include another Domino mail server that is already configured for single sign-on, complete the steps to retrieve the WebSphere LTPA key, import the WebSphere LTPA key into Lotus Domino, and then enable multiserver single sign-on authentication. For detailed instructions, see the corresponding related task topics.

• Configure SSO if Lotus Sametime and WebSphere authenticate with the same LDAP server

  If WebSphere Portal and IBM Lotus Sametime are both authenticating with the same LDAP server, SSO configuration is simple.

• Configure SSO if Lotus Sametime authenticates with Domino LDAP

  If WebSphere Portal authenticates against an LDAP directory such as Microsoft Windows Active Directory and IBM Lotus Sametime authenticates against Domino LDAP, follow the steps described here to synchronize users' names in the directories.

• Configure SSO if Sametime authenticates with Native Domino

  If WebSphere Portal authenticates against an LDAP directory and IBM Lotus Sametime authenticates against Native Lotus Domino, users are known to the Portal server and the Sametime server by different distinguished names. To ensure that single sign-on works correctly, synchronize users' names in the directories.
