I have a website running on ASP.NET MVC 4.5.2. I have an IdentityServer4 server running but when I try and authenticate against it I get an:
invalid_requestI googled a bit but I can’t find a solution. Finally, I found the way.
First, in your IdentityServer4 you have to create a new client:
public static IEnumerable GetClients() {
return new List<client> {
new Client {
ClientId = "yourid",
AllowedScopes = new List<string> { "openid" },
AllowedGrantTypes = GrantTypes.Hybrid,
RedirectUris = new List { "https://yoururl/signin-oidc" },
}
}
}
When you added the new client, you can update your other MVC project. Under App_Start open Startup.Auth.cs and add this code:
using Microsoft.Owin.Security.Cookies;
using Microsoft.Owin.Security.OpenIdConnect;
using Owin;
namespace PSC
{
public partial class Startup
{
public void ConfigureAuth(IAppBuilder app)
{
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = "Cookies"
});
app.UseOpenIdConnectAuthentication(
new OpenIdConnectAuthenticationOptions
{
Authority = "https://yourIdentityServerUrl",
ClientId = "yourid",
ResponseType = "id_token code",
SignInAsAuthenticationType = "Cookies",
RedirectUri = "https://yoururl/signin-oidc",
Scope = "openid",
});
}
}
}
You have to add a Nuget package called Microsoft.Owin.Security.OpenIdConnect.
Happy coding!
