Changing from bort to localhost, bort.caret.local makes no difference. They all connect and all get the same 500 internal server error from the Jboss lams server.
Here is a ethereal TCP level dump of the traffic
The important frames are
Frame 1: The browser doing an Ajax Call to the sakai server (btw this doesnt work at all in some browsers)
Frame 2: Sakai contacting Lams
Frame 5: Sakai doing a SOAP post to Lams
Frame 8: Lams responding with Status 500 to sakai
Frame 10: SOAP Fault code from Lams to Saka (continuation of 8)
Frame 16: Sakai response 200 to browser
It looks like everything is ok as far as the communication is concerned, but the authentication is just not happening.
What Have I got wrong ?
If I am going to fix this myself I am *going* to have to build the lams-jboss server from source.
