Get IdentityServer3 to use existing user sql database

Question

I am trying to authenticate a user against an existing user database. I have an existing database with a users table and I want the Identity Server to look at this database and get authenticate the user.

I have found examples for MembershipReboot and AspNetIdenetity, but I am confused on how I need to create my own user database mapping.

I am not trying to create an external provider e.g Facebook

Has anyone got any ideas or seen any tutorials on how this can be done?

You can implement your own IUserService, then in your startup you can set IdentityServer to use your new User Service

var factory = InMemoryFactory.Create(
    clients: Clients.Get(), 
    scopes: Scopes.Get());

var userService = new MyUserService();
factory.UserService = new Registration<IUserService>(resolver => userService);

How would this work with clients, scopes etc stored in the same database and not in memory like all the examples? This is partly what I am confused about. – Unprintable

You can write your own custom stores for those. I have yet to find any documentation but I just followed the source for the EntityFramework package found here github.com/IdentityServer/IdentityServer3.EntityFramework/tree/… – Ingenuous

Thanks for the heads up about that repo, I must have missed that before. I will follow your lead and base it off that. – Unprintable
