Hi Krish,
I'd like more insight into your Requirments.
What is the UME of the Portal ?
You have some users in AD which share the same USERID in AD and Portal
But you also have User in AD which have Diffrent USERIDs in AD and Portal.
And you want to achive SSO between AD and Portal for both set of users.
In the above case too , it is possible to achive SSO with AD for both set of users , with some tweaks in the Datasource FIle.
Let me know UME first.
Regards,
Ashish .A. Poojary
