Proxy Connect doesn't read values from Authenticate Url
I have specified Authenticate Url that will output uniqueid,name,email etc. for Proxyconnect in the required format. But when I am taking the values from Codeigniter sessions, these values disappearing in Proxyconnect. Surprisingly this was working in my development server. If I hardcode the values, it appears in Vanilla form. If anybody could point me what I may be missing it would be a great help. Thanks.
