I have created a MVC custom web application with ASP.Net Identity provider and it worked fine. Now I want to enable that single sign on authentication in Cortana skill using the connected account (similar to Expedia Skill). Do you have any suggestions?
Here are the steps that I followed for enabling the custom Authenticaiton
ASP.Net Identity provider
I have Tried the steps given here, but somehow the token is not getting back to Cortana skill. Is there any way to troubleshoot the cortana authentication flow.

I need to make my new ASP.NET Core Blazor WASM application authenticate with our on-prem ADFS/WSFederation servers. Specifically, it needs to automatically log-in users that are already logged into our AD domain, without making them go to a login page. Basic single sign on behavior. (This is how ASP.NET worked by default with ADFS/WSFederation)
I can get SSO to work without using Identity, and I get get Identity to use a log-in screen that will allow you to choose a WSFederation server as an external log-in provider, but that still begins at a log-in screen.
Can ASP.NET Core Identity work in an SSO configuration (no login screens appear for domain users), or is Identity built on the assumption that Log-in screens will be used? If it can be done, how is that set up? If I can't use Identity, can I still use other middleware like Authorization?
I really need your help. I am trying to implement IdentityServer4to generate tokens for authenticated users giving them access to the web application. However, I have set my IdentityServer Project in its own solution. Then I have a web application that runs. What I need to implement is:
1.Using Identity user signs in.
2. if successful redirect to identity server4 to generate token
3. Redirect back to application with genrated tok
You will have to add in IdentityServer configuration web application as a client with scopes. Please see here:

I'm working on a blazor web assembly, core hosted project.
The users must have a local account to use the website. For that I use default blazor authentication provider with IdentityServer.
I have a calendar page, where users can add and watch some events.
I would like to offer them the possibility to log in their google or microsoft account in order to see their personnal events in the same place.
But the google or microsoft authentication can't replace the local authentication. It must be a secondary option.
I can't find out how to manage this. All exemples I see use the RemoteAuthenticatorView.
You need to add external provider authentication to your server project by following steps described in Facebook, Google, and external provider authentication in ASP.NET Core
I'm building an API that my public mobile app (xamarin forms) will call to get information. However to delimit the users of the API to just my app for security reasons, I want the public mobile app (xamarin forms) to pass a key to be able to call the API. Is basic authentication the best option then ? Or is there another approach ?
You can use any Auth based mechanism in your web api project. The best would be the latest Identity 2.0 using Owin.
OAuth is an open standard for authentication, and enables a resource
owner to notify a resource provider that permission should be granted
to a third party in order to access their information without sharing
the resource owners identity.
In your Xamarin client project (mobile app) use the Xamarin.Auth SDK to authenticate your users. It provides many features and also helps you to scale and use Social authentication as well.
Xamarin.Auth is a cross-platform API for authenticating users and
storing their accounts. It includes OAuth authenticators that provide
support for consuming identity providers such as Google, Microsoft,
Facebook, and Twitter.
The authentication flow when consuming an OAuth identity provider is as follows:
The application redirects a browser to an identity provider URL. The
URL query parameters indicate the type of access being requested.
The identity provider handles user authentication, and returns an
authorization code to the application.
The application exchanges the authorization code, client ID, and
client secret for an access token from the identity provider.
The application uses the access token to access APIs on the identity
provider, such as requesting basic user data.
The application uses the OAuth2Authenticator and OAuth2Request classes, provided by Xamarin.Auth, to implement the application side of the authentication flow.
The detailed explanation of Authenticating Users with an Identity Provider
Using the Xamarin.Auth component for authentication implementing is available here.
We have requirement of build .NET based plugin/component for enabling Authentication against multiple IDP providers like ADFS, Azure AD and Shibboleth based on DB configuration. i.e, depending on the configurable parameter the anonymous user will be authenticated against any one of the IDPs like ADFS, Azure AD or Shibboleth IDP.
Our application URL ("https://www.contoso.com/ProcessToken.aspx") will be registered as RP Identifier in all of the 3 providers.
We won't make any web.config changes for any of the providers.
At run time, User will access common page(Proesstoken.aspx) who needs to get redirected to the any of the Login page URLs at the provider (ADFS, Shibboleth, Azure) for Authentication based on User Organization. (For ex: User A to ADFS, User B to Shibboleth etc)
After Successful authentication at the IDPs the user needs to get redirected by the provider (ADFS/ Shibboleth/ Azure AD) to the RP Url registered.
In the redirected page (ProcessToken.aspx), we are planning to get the security token and decipher the claims required.
The main intention is to decouple authentication away from application logic and it should be extendable to other providers in future.
PS: Considered options like OWIN Authentication Middle Tier, .NET Component etc.
Need guidance on How and where to start.
Have a look at IdentityServer 3 which implements this multi-auth scenario or OWIN : ASP.NET MVC application with multiple authentication options.
The main point is that you use NuGet to download all the protocols you require and than use OWIN to pull them all in via app.use.
You can configure ADFS to have Claims Provider Trust with the other IDP's Owin will acknowledge the authentication. The difficult part will be reading the attributes from the tokens. ADFS under the covers in conjunction with the Owin framework use ws-federation, I have not figured out how to read the SAML.
What gets confusing is that at one time the answer was WIF but now that 4.51 has been released, WIF was moved into Owin. The documentation for a multi-tenant application is sketchy at best.
