I have a Web application with 2 zones.
- Default: used by users on the inside using AD.
- Extranet: used by external users using a custom membership provider
What I want is for the users in the Default zone to be able to add users from the custom membership provider to SP groups. I can do this by enabling FBA on the Default zone. But I don't want the login page where the users in the Default-zone have to choose between Windows-authentication and Forms-authentication.
Is it possible to add forms users without enabling FBA in that zone? Or do I have to make a custom loginpage to automatically choose windows-authentication?
