Hi,
My goal is to write a service that provides Single Sign On mechanism for various applications with in my organization. My service need to satisfy below requirements.
 1. We have three different Active Direcotries and a SQL database for user information. Service should authentication a user against these user stores. No federation/trust available between AD's.
2. It should issue an authentication token in the form of a claim
3.. Service will be consumed by applications built on different technologies. Majority of them are .Net but older Frameworks.
Do I need to write a WCF service using WIF? Is there a way to write a RESTbased (web api) service to achieve this?
Any articles or high level steps of the approach are highly appreciated.

Thanks,

Go to the complete details ...
