Hi Guys, Any ideas?

Trying to do single sign-on between a joomla and a sharepoint portal.
  1. We have successful logins with out-of-the-box joomla
  2. But when I put registered on the articles and menus (for controlled access), the login doesnt work
  3. From joomla side, we use idemauth component
  4. From sharepoint, they use siteminder
Am thinking PHP doesnt put any data into $_POST or $_REQUEST
