Configure people awareness to work across Domino Directory and a non-Domino portal LDAP directory

Lightweight Third-Party Authentication (LTPA) is the recommended way to enable single sign-on (SSO) between WebSphere Portal and IBM Lotus Sametime and synchronize users' distinguished names (DN) when each product uses a different user or LDAP directory.

For instructions on setup, remapping user distinguished names (DN), and enabling Sametime-based people awareness, see these documents:

If you do not want to synchronize users' distinguished names, you can edit the WebSphere Portal CSEnvironment.properties file to support Sametime-based people awareness by completing the steps below. Keep in mind that if the users' names distinguished names are not synchronized, single sign-on to meetings is not available.

  1. Locate the property CS_SERVER_SAMETIME_1.nameFormatForResolve.

  2. Remove the comment tag (#) from the beginning of the line, if a comment tag is present.

  3. Change the value for this property to loginName or cn.

    For example, CS_SERVER_SAMETIME_1.nameFormatForResolve=loginName

    The value loginName is the preferred setting.

    The value loginName in the LDAP for WebSphere Portal should be present in the Domino Directory as the Short Name/UserID field.

    If cn is specified, the Common Name in the LDAP for WebSphere Portal should be present in the Domino Directory, as one of the entries in the User Name field.

  4. Locate the property CS_SERVER_SAMETIME_1.dnNameSeparator.

  5. Remove the comment tag (#) from the beginning of the line, if a comment tag is present.

  6. Change the value for this property to /.

    For example, CS_SERVER_SAMETIME_1.dnNameSeparator=/.

  7. Locate the property CS_SERVER_SAMETIME_1.useLTPAToken.

  8. Remove the comment tag (#) from the beginning of the line, if a comment tag is present.

  9. Change the value for this property to false.
