Neo4j.AspNet.Identity

Custom ASP.NET Identity provider for the Neo4j Graph Database

Purpose

ASP.NET MVC 5 shipped with a new Identity system (in the Microsoft.AspNet.Identity.Core package) in order to support both local login and remote logins via OpenID/OAuth, but only ships with an Entity Framework provider (Microsoft.AspNet.Identity.EntityFramework).

Breaking Changes in 2.x

• Upgraded Neo4jClient to 3.x - adding Bolt Support.
  • You will need 2.x if you're using Neo4jClient 3+

Current Builds

Features

• Drop-in replacement ASP.NET Identity with Neo4j as the backing store.
• Contains the same IdentityUser class used by the EntityFramework provider in the MVC 5 project template
• Supports additional profile properties on your application's user model.
• Provides UserStore implementation that implements the same interfaces as the EntityFramework version:
  • IUserStore
  • IUserLoginStore
  • IUserRoleStore
  • IUserClaimStore
  • IUserPasswordStore
  • IUserSecurityStampStore

Instructions

These instructions assume you know how to set up Neo4j within an MVC application.

Using

1. Create a new ASP.NET MVC 5 project, choosing the Individual User Accounts authentication type.

   1. Update all Nuget packages to latest versions (in particular 'Microsoft ASP.NET Identity Core')
   2. Install-Package Neo4j.Aspnet.Identity
   3. Remove the Entity Framework packages and replace with Neo4j Identity:
      1. Uninstall-Package Microsoft.AspNet.Identity.EntityFramework
      2. Uninstall-Package EntityFramework

2. Delete ~/Models/IdentityModels.cs

3. In ~/App_Start/IdentityConfig.cs

   1. Change the 'ApplicationUserManager' to use the Neo4jUserStore (as below)
   2. Change the 'ApplicationUserManager' to get the GraphClient from Owin (as below)

   var manager = new ApplicationUserManager(new Neo4jUserStore<ApplicationUser>(context.Get<GraphClientWrapper>().GraphClient));

4. In ~/App_Start/Startup.Auth.cs

   1. Add 'using Neo4j.AspNet.Identity'
   2. Add the following Method:

   private void ConfigureNeo4j(IAppBuilder app)
   {
       app.CreatePerOwinContext(() => {
           var gc = new GraphClient(new Uri("http://localhost.:7474/db/data"));
           gc.Connect();
           var gcw = new GraphClientWrapper(gc);
           return gcw;
       });
   }
   

   3. Replace the line about creating the ApplicationDbContext:

   app.CreatePerOwinContext(ApplicationDbContext.Create);

   with:

   ConfigureNeo4j(app);

5. In ~/Controllers/AccountController.cs

   1. Remove the namespace: Microsoft.AspNet.Identity.EntityFramework
   2. Add the namespace: using Neo4j.AspNet.Identity
