We need a SharePoint authentication provider for authenticating against a MySQL database.
* The authentication provider must work with SharePoint Services 3.0.
* Delivery must be as source code, in the form of a Visual Studio project. We will build the provider ourselves.
* The code must be properly documented with comments.
* Configuration values (database server, username, password, table and column names) must be in an easily editable XML-file, and not hard coded in the source code.
