如何将Asp.Net身份与Azure AD授权结合在一起

How to integrate Asp.Net Identity with Azure AD Authorization

Is it possible to integrate Asp.Net Identity with Azure AD Authorization by means of OpenIdConnect? I'd like to have a both authorization providers one for local authorization ( by means of standart Asp.net core Identity and second by means of Azure AD

        _services
            .AddAuthentication(options =>
            {
                options.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
                options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
                options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            })
            .AddOpenIdConnect(OpenIdConnectDefaults.AuthenticationScheme, options =>
            {
                options.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
                options.ClientId = clientId;
                options.ClientSecret = clientSecret;
                options.Authority = $"{baseAuthorityUrl}/{tenantId}/v2.0";
                options.CallbackPath = new PathString(callBackPath);
                options.Scope.Add("email");
                options.Scope.Add("profile");
                options.ResponseType = "code id_token";

                options.SaveTokens = true;
                options.GetClaimsFromUserInfoEndpoint = true;
                options.TokenValidationParameters = new TokenValidationParameters
                {
                    NameClaimType = "name"
                };
            })

This works for Azure AD Authorization, but i can't change authorization method from Azure AD to ASp.Net Identity. Any help is much appreciated

I'd suggest using the default ASP.NET Identity template to start the project :

1. Create new application with ASP.NET Identity (Individual User Accounts template).

2. Seed the database with Migrations Add-Migration Name , Update-Database .

3. Add your OIDC provider :

    services .AddAuthentication(options => { options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme; options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme; }).AddCookie() .AddOpenIdConnect(OpenIdConnectDefaults.AuthenticationScheme, options => { options.SignInScheme = IdentityConstants.ExternalScheme; options.ClientId = ClientId; options.ClientSecret = ClientSecret; options.Authority = $"{baseAuthorityUrl}/{tenantId}/v2.0"; options.CallbackPath = new PathString("/signin-oidc"); options.Scope.Add("email"); options.Scope.Add("profile"); options.ResponseType = "code id_token"; options.SaveTokens = true; options.GetClaimsFromUserInfoEndpoint = true; options.TokenValidationParameters = new TokenValidationParameters { NameClaimType = "name" }; }); 

Make sure using IdentityConstants.ExternalScheme for SignInScheme otherwise the Identity won't accept external login information correctly .

Asp.net will create a local account that associates your external account , so that you can perform authorization with your local identity system .
