Enabling SSO on the Community Server

The HCL® Sametime® Community Server uses authentication by token to authenticate connections that occur after a user has authenticated once using password authentication.

Single sign-on (SSO) removes the need for a user to re-enter authentication credentials when reconnecting to a server, accessing different servers, using HCL Sametime® web clients, or Domino® applications that connect to an HCL Sametime® Community Server. Authentication by token is the method that Sametime® uses to support single sign-on.

The Sametime® Community Server uses the single sign-on feature of the underlying Domino® server to authenticate users by token.

The Domino® SSO feature must be enabled on a Sametime® Community Server. If the Domino® SSO feature is not enabled on the Domino® server when you install the Sametime® Community Server, the Sametime® Community Server installation automatically enables and configures the Domino® SSO feature. In some environments, you might need to alter the default SSO configuration provided by the Sametime® Community Server installation. For more information, see Altering the Domino® Web SSO configuration following the Sametime® server installation.

The user must enter the fully qualified domain name of the Sametime® Community Server (for example, sametime.example.com) in the web browser URL locator when accessing the Sametime® Community Server to authenticate successfully using SSO.

Note: When configuring a Sametime® Community Server to use Internet sites, these settings must be configured in the [AuthToken] section of the sametime.ini file:
  • ST_TOKEN_TYPE must contain the name of the Web SSO document used by the IBM Sametime® Community Server. The default value is LtpaToken.
  • ST_ORG_NAME must contain the organization name that is set in the Web SSO document used by the Sametime® Community Server. The default value is an empty organization name.

For additional information about the Domino® Internet Sites configuration see the Domino® Administration documentation.
