The required fully-qualified server name

The user must enter the fully qualified DNS name of the IBM® Sametime® server (for example, sametimeserver.meetings.acme.com) in the web browser URL locator when accessing the Sametime server to authenticate with a Sametime server.

The Domino® Single Sign-On (SSO) feature must be enabled on the Sametime server. The Domino SSO feature requires the user to enter the fully qualified DNS name of the server for a successful authentication. For more information, see Authentication by token using LTPA and Sametime tokens.
