Delegated Authentication - Invoke embedded-crowd login
This is Sung. I think I found another problem with Siteminder and Confluence 3.5.x.

Please look at the following link:
Can you perform a similar process as the link suggests? Fire the UserAuthenticatedEvent so that post-login processing is triggered.
