Owin OpenId Callback url - asp.net-mvc

I'm working in implementing OpenId in a .NET MVC application.
I have used: https://learn.microsoft.com/en-us/azure/active-directory/develop/quickstart-v1-aspnet-webapp
as a starting guide. It is working, but i have 1 question regarding RedirectUri and CallbackPath.
If i only use RedirectUri, the callback page in my application gets a 302 redirection.
If i use CallbackPath the callback page is actually hit.
It is not really clear from the example what is going on? This is from MS:
"An optional constrained path on which to process the authentication callback. If not provided and RedirectUri is available, this value will be generated from RedirectUri."
I'm using [Authorize] attribute on my controllers.
Code Startup.cs:
public void Configuration(IAppBuilder app)
{
app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
app.UseCookieAuthentication(new CookieAuthenticationOptions());
var openIdOptions = new OpenIdConnectAuthenticationOptions
{
// Sets the ClientId, authority, RedirectUri as obtained from web.config
ClientId = ApplicationIdentifier,
Authority = FederationGateway,
RedirectUri = RedirectUrl,
ClientSecret = AppToken,
AuthenticationMode = AuthenticationMode.Active,
//CallbackPath = new PathString("/callback/"),
// PostLogoutRedirectUri is the page that users will be redirected to after sign-out. In this case, it is using the home page
PostLogoutRedirectUri = "~/home/loggedout/",
//Scope is the requested scope: OpenIdConnectScopes.OpenIdProfileis equivalent to the string 'openid profile': in the consent screen, this will result in 'Sign you in and read your profile'
Scope = OpenIdConnectScope.OpenIdProfile,
// ResponseType is set to request the id_token - which contains basic information about the signed-in user
////ResponseType = OpenIdConnectResponseType.IdToken,
ResponseType = OpenIdConnectResponseType.IdTokenToken,
// ValidateIssuer set to false to allow work accounts from any organization to sign in to your application
// To only allow users from a single organizations, set ValidateIssuer to true and 'tenant' setting in web.config to the tenant name or Id (example: contoso.onmicrosoft.com)
// To allow users from only a list of specific organizations, set ValidateIssuer to true and use ValidIssuers parameter
TokenValidationParameters = new TokenValidationParameters()
{
ValidateIssuer = false
},
// OpenIdConnectAuthenticationNotifications configures OWIN to send notification of failed authentications to OnAuthenticationFailed method
Notifications = new OpenIdConnectAuthenticationNotifications
{
AuthenticationFailed = OnAuthenticationFailed,
SecurityTokenValidated = OnSecurityTokenValidated
}
};
app.UseOpenIdConnectAuthentication(openIdOptions);
AntiForgeryConfig.UniqueClaimTypeIdentifier = IdentityNameIdentifier;
}

Mixing cookie external login using Azure AD and individual account in MVC5

I am getting problems with application cookie and external cookie that are integrated login with Azure AD to my web app using MVC5. Currently, my local account work correctly but external account (Google and Azure AD) cannot map external cookie to local cookie. My code get userId return incorrect user Id.
IIdentity ident = HttpContext.Current.GetOwinContext().Request.User.Identity;
ident.GetUserId()
Below is my startup.cs
public partial class Startup
{
// The Client ID is used by the application to uniquely identify itself to Azure AD.
string clientId = System.Configuration.ConfigurationManager.AppSettings["ClientId"];
// RedirectUri is the URL where the user will be redirected to after they sign in.
string redirectUri = System.Configuration.ConfigurationManager.AppSettings["RedirectUri"];
string postLogoutRedirectUri = System.Configuration.ConfigurationManager.AppSettings["PostLogoutRedirectUri"];
// Tenant is the tenant ID (e.g. contoso.onmicrosoft.com, or 'common' for multi-tenant)
static string tenant = System.Configuration.ConfigurationManager.AppSettings["Tenant"];
// Authority is the URL for authority, composed by Microsoft identity platform endpoint and the tenant name (e.g. https://login.microsoftonline.com/contoso.onmicrosoft.com/v2.0)
string authority = String.Format(System.Globalization.CultureInfo.InvariantCulture, System.Configuration.ConfigurationManager.AppSettings["Authority"], tenant);
// For more information on configuring authentication, please visit http://go.microsoft.com/fwlink/?LinkId=301864

Provider = new CookieAuthenticationProvider
{
OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<AppUserManager, AppUser>(

// In a real application you would use ValidateIssuer = true for additional checks and security.
ValidateIssuer = false,
},

},
// Handling SameSite cookie according to https://learn.microsoft.com/en-us/aspnet/samesite/owin-samesite

new SystemWebCookieManager()),
};
return options;
}
private Task OnAuthenticationFailed(AuthenticationFailedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> context)
{
// Handle any unexpected errors during sign in
context.OwinContext.Response.Redirect("/Error?message=" + context.Exception.Message);
context.HandleResponse(); // Suppress the exception
return Task.FromResult(0);
}
}
Below is sign out method which is called before sign in
var authenticationTypes = new string[] {
DefaultAuthenticationTypes.ApplicationCookie,
DefaultAuthenticationTypes.ExternalCookie,
};
AuthManager.SignOut(authenticationTypes);
I also already tried apply many fixed posts related to this but it does not work. How can we resolve external cookie map to local cookie?
Finally, I found workaround solutions below:
First if you don want to use Open id connect use the link below
Use Azure AD only for Authentication and not Authorization
I use Kentor.OwinCookieSaver to resolve my problem

Azure B2C authentication redirects locally, but not when hosted on Azure

I'm new to Azure AD B2C. I'm trying to set up azure B2C authentication for an MVC application.
The login works fine locally, but when it's not working on server.
The application is hosted on Azure AD.
I don't know if I missed something!! Can someone please help?
private OpenIdConnectAuthenticationOptions CreateOptionsFromPolicy(string policy)
{
return new OpenIdConnectAuthenticationOptions
{
// set the authentication type to the id of the policy
MetadataAddress = metaDataAddress,
AuthenticationType = policy,
// These are standard OpenID Connect parameters, with values pulled from web.config
ClientId = clientId,
//ClientSecret = clientSecret,
RedirectUri = redirectUri,
PostLogoutRedirectUri = redirectUri,
Notifications = new OpenIdConnectAuthenticationNotifications
{
AuthenticationFailed = AuthenticationFailed,
},
Scope = "openid",
ResponseType = "id_token",
// used for displaying the user's name in the navigation bar.
TokenValidationParameters = new TokenValidationParameters
{
NameClaimType = "name",
RoleClaimType = "role",
SaveSigninToken = true
}
};
}
When it is deployed on to the server, after sign in, it is not returning to the application. Instead the page seems to blink and in between I can see something displayed as "As part of the authentication process the page is displayed several times, please click the button to continue"..
Startup.cs file seems alright to me.Couple things to cross check:
redirectUri matches with the website
Here is my signup and sign in action method:
public void SignIn()
{
if (!Request.IsAuthenticated)
{
HttpContext.GetOwinContext().Authentication.Challenge(
new AuthenticationProperties() { RedirectUri = "/" }, Startup.SignInPolicyId);
}
}
public void SignUp()
{
if (!Request.IsAuthenticated)
{
HttpContext.GetOwinContext().Authentication.Challenge(
new AuthenticationProperties() { RedirectUri = "/" }, Startup.SignUpPolicyId);
}
}
I have followed below github repo and it worked for me. Try this and see if it works
https://github.com/tjoudeh/Azure-Active-Directory-B2C/tree/master/AADB2C.WebClientMvc/Controllers
Reference:

Please provide the detailed error with entire code base will try to reproduce at my end.

ADFS Authentication with multiple account

I am authenticating user based on ADFS. I am adding claim provider trust to my adfs server so that I could use multiple accounts to login.
I am able to authenticate user for my adfs server whereas If I use other claim provider trust adfs to authenticate I am not able to return token
app.UseOpenIdConnectAuthentication(
new OpenIdConnectAuthenticationOptions
{
ClientId = clientId,
//Authority = authority,
MetadataAddress = metadataAddress,
RedirectUri = postLogoutRedirectUri,
PostLogoutRedirectUri = postLogoutRedirectUri,
Notifications = new OpenIdConnectAuthenticationNotifications
{
AuthenticationFailed = context =>
{
context.HandleResponse();
context.Response.Redirect("/Error?message=" + context.Exception.Message);
return Task.FromResult(0);
},
AuthorizationCodeReceived = context =>
{
string authorizationCode = context.Code;
// (tricky) the authorizationCode is available here to use, but...
return Task.FromResult(0);
}
});
When I enter user credentials and hit login I get back to initial screen

How to pass login_hint while using OpenIdConnectAuthentication with azure AD?

I'm using OpenIdConnectAuthentication to login my users on azure AD. I've an asp.net mvc web app. I register the OpenIdConnectAuthentication as the following in the startup class and use the [Authorize] attribute on top of the controllers. Everything works fine, but I couldn't figure out how to make the login_hint work. I tried passing it as a query string while calling the action. Any idea on how to make the login_hint work? Thanks in advance!
app.UseOpenIdConnectAuthentication(
new OpenIdConnectAuthenticationOptions
{
ClientId = clientId,
Authority = authority,
PostLogoutRedirectUri = postLogoutRedirectUri
});
Use the RedirectToIdentityProvider notification. This allows you to modify the request before the user is redirected to the identity provider. Vittorio's blog has additional details.
app.UseOpenIdConnectAuthentication(
new OpenIdConnectAuthenticationOptions
{
ClientId = clientId,
Authority = authority,
PostLogoutRedirectUri = postLogoutRedirectUri,
Notifications = new OpenIdConnectAuthenticationNotifications()
{
RedirectToIdentityProvider = (context) =>
{
context.ProtocolMessage.LoginHint = "";
}
}
});
For more information you can check this document
https://learn.microsoft.com/en-us/azure/active-directory-b2c/enable-authentication-web-application-options
private async Task OnRedirectToIdentityProviderFunc(RedirectContext context)
{
context.ProtocolMessage.LoginHint = "emily#contoso.com";
await Task.CompletedTask.ConfigureAwait(false);
}
