Permissions for Stored Procedures generated by VS 2005

I have a DataSet (Data Component in Beta 1) and I want to add Fill andGet methods by using a Stored Procedure that was created by VS 2005 (aspnet_Membership_GetAllUsers). I probably need to use Enterprise Manager to do so but I am not sure what permissions I need to set and how to set them.

Stored Proc permissions are DBO(database owner). Hope this helps.
