How to Use Windows SSO

[johnmcwho]

I've one great problem(should be) how is it possible to secure Jboss by using the Windows SSO. For example my Application is a standard web application with form authenification via mysql. And now some of my customer use Microsoft CRM and SharePoint with SSO, so they ask for one login. They login on the CRM on also get access to JBoss web application.
Is there any idea, i'm now a little bit blocked. Thanks.
