We're looking for an SSO solution that can be hosted on JBoss 4.0.x. Currently we're able to get OpenSSO to work - but would like to compare against another product. Any recommendations? (PicketLink seems to require JBoss 5.1). Is JBoss Federated SSO the same as PicketLink?
(Yes, I'd like to upgrade JBoss, but the client has a lot of JSF pages that just won't deploy on a later version due to classloader issues)
