I've a ASP.NET MVC website which uses an ASP.NET WebAPI to authenticate. I've using ThinkTecture IdentityModel for basic authentication and session token, which works fine locally and in Azure Websites. However, I had to migrate to Azure Cloud services and now I can't authenticate with the token, always receiving the 401 error, but with just username and password works fine.
The only difference I can guess is that I've to deal with IIS now. Is there any modification required to allow authentication with token?
UPDATED:
I'm not using any Web.Config configuration for authentication, just using the following code in WebAPIConfig.
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
var authConfig = new AuthenticationConfiguration
{
RequireSsl = true,
EnableSessionToken = true,
SendWwwAuthenticateResponseHeaders = true,
SessionToken = new SessionTokenConfiguration()
{
DefaultTokenLifetime = System.TimeSpan.FromDays(1.0)
}
};
// setup authentication against membership
authConfig.AddBasicAuthentication(
(userName, password) => WebSecurity.Login(userName, password, true)
);
config.MessageHandlers.Add(new AuthenticationHandler(authConfig));
}
I'd set a fixed signing key on the SessionTokenConfiguration. You definitely need that.

In my web project i want to enable the user to login with username / password and Microsoft Account.
Tech - Stack:
Asp.Net Core WebApi
Angular
Azure App Service
First i created the username / password login. Like this:
StartUp.cs:
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme).AddJwtBearer(options =>
{
options.TokenValidationParameters = new Microsoft.IdentityModel.Tokens.TokenValidationParameters
{
ValidateIssuerSigningKey = true,
IssuerSigningKey = new SymmetricSecurityKey(System.Text.Encoding.UTF8.GetBytes(Configuration["JWTKey"].ToString())),
ValidateIssuer = false,
ValidateAudience = false,
ValidateLifetime = true
};
});
Login Method:
public async Task<IActionResult> ClassicAuth(AuthRequest authRequest)
{
tbl_Person person = await _standardRepository.Login(authRequest.Username, authRequest.Password);
if (person != null)
{
var claims = new[]
{
new Claim(ClaimTypes.GivenName, person.PER_T_Firstname),
};
var key = new SymmetricSecurityKey(System.Text.Encoding.UTF8.GetBytes(_config["JWTKey"].ToString()));
var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha512Signature);
var tokenDescriptor = new SecurityTokenDescriptor
{
Subject = new ClaimsIdentity(claims),
Expires = DateTime.Now.AddHours(24),
SigningCredentials = creds
};
var tokenHandler = new JwtSecurityTokenHandler();
var token = tokenHandler.CreateToken(tokenDescriptor);
return Ok(tokenHandler.WriteToken(token));
}
else
return Unauthorized("Invalid login data");
}
And secured my api enpoints with [Authorize].So far so good...that works.
Now i want to add a login method with Microsoft Account. I use Azure App Service Authentication / Authorization for that (https://learn.microsoft.com/de-de/azure/app-service/overview-authentication-authorization).
I configured the auth provider and i'm able to start the auth flow with a custom link in my angular app:
Login with Microsoft - Account
This works and i can retrieve the access token from my angular app with this:
this.httpClient.get("https://mysite.azurewebsites.net/.auth/me").subscribe(res => {
console.log(res[0].access_token);
});
Now the problem:
access_token seems not a valid JWT Token. If i copy the token and go to https://jwt.io/ it is invalid.
When i pass the token to my API i get a 401 - Response. With seems logical because my API checks if the JWT Token is signed with my custom JWT Key and not the Key from Microsoft.
How can I make both login methods work together? I may have some basic understanding problems at the moment.
It seems you want your Angular app calling an ASP.NET Core Web API secured with Azure Active Directory, here is a sample works well for that.
The most important step is register the app in AAD.
By the way, if you want to enable users to login one project with multiple ways in azure, you can use multiple sign-in providers.
I am unable to signout from a .Net core Web App while using Azure AD to login.
When i try to login using a different email, its just logging in as the previous user who logged in. Its not even asking for password when the new user is trying to login.
I have tried the following approaches but -
// Send an OpenID Connect sign-out request.
HttpContext.GetOwinContext().Authentication.SignOut(
OpenIdConnectAuthenticationDefaults.AuthenticationType, CookieAuthenticationDefaults.AuthenticationType);
OR
HttpContext.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme);
or
if (HttpContext.User.Identity.IsAuthenticated)
{
await HttpContext.Authentication.SignOutAsync(settings.SignInPolicyId);
await HttpContext.Authentication.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme);
}
None of these work on .Net Core.
This code below builds and runs on .net core but it doesnt completely logout the user.
Request.GetOwinContext().Authentication.SignOut(new AuthenticationProperties { RedirectUri = clsCommonFunction.GetLoginURL() });
Please help.
Here is the SignOut method for ASP.NET Core.
[HttpGet]
public IActionResult SignOut()
{
var callbackUrl = Url.Action(nameof(SignedOut), "Account", values: null, protocol: Request.Scheme);
return SignOut(
new AuthenticationProperties { RedirectUri = callbackUrl },
CookieAuthenticationDefaults.AuthenticationScheme,
OpenIdConnectDefaults.AuthenticationScheme);
}
[HttpGet]
public IActionResult SignedOut()
{
if (User.Identity.IsAuthenticated)
{
// Redirect to home page if the user is authenticated.
return RedirectToAction(nameof(HomeController.Index), "Home");
}
return View();
}
Its not even asking for password when the new user is trying to
login.
Please clear the browser cache Ctrl+F5.
I have a web forms app which I am trying to authenticate against Azure AD using SAML 2/Kentor/Owin. I think I have things configured OK, but when my login page issues the following command I am not being redirected to a login page.
HttpContext.Current.GetOwinContext().Authentication.Challenge(new AuthenticationProperties { RedirectUri = "/Login.aspx" });
Here is my startup.cs
private void ConfigureSAML2Authentication(IAppBuilder app) {
var authServicesOptions = new KentorAuthServicesAuthenticationOptions(false)
{
SPOptions = new SPOptions
{
EntityId = new EntityId("https://login.microsoftonline.com/<tenant guid>/saml2")
}
},
AuthenticationType = "KentorAuthServices",
Caption = "ADFS - SAML2p",
};
authServicesOptions.IdentityProviders.Add(new IdentityProvider(
new EntityId("https://sts.windows.net/<tenant guid>/"),
authServicesOptions.SPOptions)
{
MetadataLocation = "https://login.microsoftonline.com/<tenant guid>/federationmetadata/2007-06/federationmetadata.xml",
LoadMetadata = true,
});
app.UseKentorAuthServicesAuthentication(authServicesOptions);
}
As far as I can tell looking at the Network Tools in chrome, no auth request is being sent at all. Is anyone able to tell me why?
The AuthServices middleware is configured as Passive by default, so it will not automatically respond to an authentication challenge unless you specify the provider.
When you issue the challenge you should specify the same AuthenticationType that you used when the middleware was set up. By default this is "KentorAuthServices" but can be changed.
If you change your challenge to include the type, it should trigger the redirect:
HttpContext.Current.GetOwinContext().Authentication.Challenge(new AuthenticationProperties { RedirectUri = "/Login.aspx" }, "KentorAuthServices");
I am having some issue to make work 2 auth provider at the same time for servicestack.
I am using the : JWT Tokens - Allowing users to authenticate with JWT Tokens I am my users get authenticate fine.
Still Now I would like to use the API Keys - Allowing users to authenticate with API Keys for a few external 3rd Parties user access.
Still when I Configure both my users allready authenticate by JWT Tokens doesnt work anymore.
Here is my configuration AuthProvider configuration :
IAuthProvider[] providers = new IAuthProvider[]
{
new JwtAuthProviderReader(this.AppSettings)
{
HashAlgorithm = "RS256",
PrivateKeyXml = this.AppSettings.GetString("TokenPrivateKeyXml"),
PublicKeyXml = this.AppSettings.GetString("TokenPublicKeyXml"),
RequireSecureConnection = this.AppSettings.Get<bool>("TokenUseHttps"),
EncryptPayload = this.AppSettings.Get<bool>("TokenEncryptPayload"),
PopulateSessionFilter = (session, obj, req) =>
{
ApplicationUserSession customSession = session as ApplicationUserSession;
if (customSession != null)
{
customSession.TimeZoneName = obj["TimeZoneName"];
customSession.Type = (FbEnums.UserType) (obj["UserType"].ToInt());
if (Guid.TryParse(obj["RefIdGuid"], out Guid result))
{
customSession.RefIdGuid = result;
}
}
},
},
new ApiKeyAuthProvider(AppSettings)
{
RequireSecureConnection = false
}
};
I am genereting fine the token with JwtAuth. Still It look like servicestack is not accepting my token as a valid session, because now whenever I do :
var session = httpReq.GetSession();
session.IsAuthenticated --> is always FALSE
If my remove ApiKeyAuthProvider from the configuration, token from JwtAuth working fine again.
How do I make both provider works together and tell servicestack tham some users will use JwtAuth and others ApiKeyAuth ?
You need to call a Service that requires Authentication, e.g. has the [Authenticate] attribute in order to trigger pre-Authentication for the IAuthWithRequest providers like JWT and API Key AuthProviders.
The examples I've seen for using Azure B2C with Web API show app.UseOAuthBearerAuthentication (as shown below), however my ASP .NET 5 Web API project uses IApplicationBuilder (not IAppBuilder) and UseOAuthBearerAuthentication does not exist. I've tried app.UseOpenIdConnectAuthentication, however I believe this uses cookies and I couldn't get it working using a Xamarin app as a client. I've tried app.UseWindowsAzureActiveDirectoryBearerAuthentication but I believe this is for standard Azure AD (not B2C) is that true? Any ideas how to get Azure B2C working with the very latest ASP .NET Web API?
Thanks!!!
public void ConfigureAuth(IAppBuilder app)
{
TokenValidationParameters tvps = new TokenValidationParameters
{
// This is where you specify that your API only accepts tokens from its own clients
ValidAudience = clientId,
};
app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions
{
// This SecurityTokenProvider fetches the Azure AD B2C metadata & signing keys from the OpenIDConnect metadata endpoint
AccessTokenFormat = new JwtFormat(tvps, new OpenIdConnectCachingSecurityTokenProvider(String.Format(aadInstance, tenant, "v2.0", discoverySuffix, commonPolicy)))
});
}
This works for me. I hope it helps someone else who is looking to use Azure B2C with the latest .NET Web API framework:
public void ConfigureAuth(IApplicationBuilder app, IOptions<PolicySettings> policySettings)
{
app.UseJwtBearerAuthentication(new JwtBearerOptions
{
AuthenticationScheme = JwtBearerDefaults.AuthenticationScheme,
AutomaticAuthenticate = true,
AutomaticChallenge = true,
MetadataAddress = "https://login.microsoftonline.com/[my-tenant].onmicrosoft.com/v2.0/.well-known/openid-configuration?p=B2C_1_my-signup-signin-policy",
Audience = "[My-Azure-App-Guid]",
Events = new JwtBearerEvents
{
OnTokenValidated= ctx =>
{
var nameClaim = ctx.AuthenticationTicket.Principal.FindFirst("name");
if (nameClaim != null)
{
var claimsIdentity = (System.Security.Claims.ClaimsIdentity)ctx.AuthenticationTicket.Principal.Identity;
claimsIdentity.AddClaim(new System.Security.Claims.Claim(System.Security.Claims.ClaimTypes.Name, nameClaim.Value));
}
return Task.FromResult(0);
},
OnAuthenticationFailed = ctx =>
{
ctx.SkipToNextMiddleware();
return Task.FromResult(0);
}
}
});
}
If the JWT token is available in your client, then you can use JwtBearerAuthentication in the Web API. The JWT issued by Azure B2C ( social logins) can be used as a token to get authenticated in the Web API.

In this sample the client is a web app
