Can't create new users: Method or Operation Not Implemented


I set up forms based authentication. I followed the FBA Pack Documentation.

I have the FBA Pack deployed and the web parts are on pages and are accessible. When I go to Manage Forms Based Auth Users, I see a list of Active Directory users. When I go to "New User", I get the following error:

Sorry, something went wrong
The method or operation is not implemented.
Correlation ID: e74f949d-19a1-2007-3903-772ec64cc7be

Ideally I'm picturing the FBA Pack managing SQL users, not the AD users, so I'm a little confused. Did I miss something in the configuration?

Yeah, from what's happening it looks like your web application is setup against an AD membership provider instead of a SQL membership provider. Unfortunately only the SQL Membership provider is supported.
