I created a LinkedServer on MS SQL Server 2005 pointing to my Active Directory. Nothing too fancy. Simple LinkedServer with ReadOnlyAdmin Account assigned to CONNECTAS Property.

Then I created some storedprocedures to retreive some data from the LinkedServer. Again nothing too fancy. Just a few simple LDAP Queries.

Then I created a SQL Endpoint to expose these stored procedures as Web services. Using Visual Studio 2008, everything is fine and dandy. It finds the endpoint, gets the list of the methods available and runs smoothly. Cool.

But the Sharpeoint Add Web Service somehow doesn't work! It finds the WSDL file no prob. Retrieves the list of functions and parameterss n all but just simply doesn't run them! Any advice or where I should start checking?
