I’ve made our Adobe Connect service single sign-on for our employees and nicely work for our guests – all behind Novell iChain accelerator. It was a pain in the neck to make them work together. A lot of weird HTTP header and URI issues. Even though Adobe Connect offers a nice API to manage meetings, log in users and guests, it’s really proxy-unfriendly.
