SpringSecurity with Tomcat SingleSignOn Valve

[dmfrey]

Can spring security form login be used to populate the contain security principal so that it can be used with the Tomcat SingleSignOn and Security Realm to allow for A&A across webapps in the container?

If yes, how would I configure spring security to do so? All my apps are using Spring Security 3.1.2.

The reason for this is I need to provide A&A to another war in the same container that is a plain old JEE web application.
