Help Setting up a Openfire server with SSO.

Hi, i am trying to get SSO for our jabber clients in the company. Have any of you guys managed to get SSO in an Active Directoy environment? i have gone trough all the tutorials in the openfire forum but most of them are abandoned and there is much confusion, i have tried quite a few How-To's but i can't get it to work. The scenario is: Openfire installed in a Linux Box - Active Directory environment and jabber client that support integrated windows authentication (spark, pandion) Thanks
