Hi Jethro, We're having issues without using EZproxy. Our IdP authenticates when I'm off campus, but behaves exactly as you describe on campus. The explanation given is: "The problem was previously being caused by the load balancing configuration. Node (server) A's Shibboleth login was redirecting to node B's Shibboleth login upon a Shibboleth access attempt, batting the login attempts back and forth. However, due to further testing, there is only one node serving Shibboleth requests at the moment, so if you are still experiencing the problem, it will almost certainly be a caching issue." I'm still getting your problem today -- haven't heard if our web cache has been cleared yet.

Anyone heard of issues with dawsonera? Specifically, when accessing via a proxy, They claim to have performed an upgrade: "As part of the continuous improvement to the Dawsonera platform we will be upgrading the Shibboleth component to support the Shibboleth 2 protocol. This will involve a change to the federation metadata (attached). The metadata will be updated at your federation at 6pm on 3rd December 2009. " Since 3rd December, when we select our site from their WAYF and login, we get redirected back to the WAYF again. Testing by bypassing proxy, after WAYF connection and local IdP login one is directed to a home page where there is a "Login to reader portal" option, "enter your insitutional username and password", and clicking that takes you straight to an accept terms and conditions page, and success thereafter. I note that their site is being served through a load balancer 93.91.19.147 isplb03-aux1.semantico.net. I wonder if the fact that we are connecting to it through proxy is giving some issue. Does any of this ring any bells with anyone? I've have pretty much run out of avenues to investigate. Jethro. . . . . . . . . . . . . . . . . . . . . . . . . .
