Wicket and Single Sign-on?

I'm relatively new to Wicket and trying not to carry forward any
preconceived notions from other frameworks.  What is the
suggested/preferred means of authenticating single sign-on requests
from another application?  In particular, I'm thinking about MAC
(http://en.wikipedia.org/wiki/Message_authentication_code) but could
potentially use a proper single sign-on framework ala CAS.  I've
searched the list and saw some mention of using a servlet filter?  Any
guidance would be appreciated.

Thanks,
Jeff
