Looking for a high level design on implementing SharePoint 2010 Initiated workflow to Siteminder Protected application and vice versa.
Example. I have 2 Sites say a.com and b.com. Where a.com is protected by siteminder against Active Directory[sayad.com] and b.com is a sharepoint site  and ia authenticated against same AD.com however this site is non siteminder protected.
Use Case 1: User logs to a.com and if user want to access b.com then sso should be enabled
Use Case 2: User logs to b.com and if user want to access a.com then sso should be enabled
