I'm trying to allow CAC (Common Access Card) to present a X.509 client certificate to login to jetspeed. The user authentication in jetspeed seems very configurable but seems to be centered around user name/password being passed around. Is there a way to override the DefaultLoginModule. I found a reference in login.conf in the source but doesn't seem like I can change it out for another implementation like CredentialHandler for example. If anyone can point me to an example where something like this was done or just how to change defaultLoginModule it would help.
