These two don't really have SSO, just integrate, realize single landing, using token as a login marker
As a user verification server, Domino is the way to log in to the Tomcat system. Query the user's token, does not exist, turn to Names.nsf? login to log in, existence, no steering
As a Domino server, HTTP and DIIOP services must be running,
Note: 1 There is also a kind of DSAPI to achieve, WebSphere Fish Domino has SSO is
2 Domino Tomcat Redirector only uses Tomcat as a ServerT JSP server, no single landing 3 has a verification server through Indierty Server, which is very good, such as Sun, open source SourceId, etc.
