Created a web based application which needs to integrate forms authentication and SSO. Currently forms authentication will validate all the registered users.
What I need is to integrate SSO as well in to the application. ie, If the user not authenticated then redirect to identity server (Okta) configured with WS-Fed and added the application, validate and response to landing page. Please can you help on this. Please let me know if any more information is required.
Can you please explain this statement " If the user not authenticated then redirect to identity server (Okta) configured with WS-Fed and added the application"?
Please see this link https://github.com/okta/okta-music-store. Under section "Adding Single-sign on to your Music Store" you can see how C# sdk can be used to implement single sign on.
Essentially what you need is a cookieToken from Okta. Using cookieToken as one time token and a redirect url (Can be your app url) you can use /login/sessionCookieRedirect?token=&redirectUrl=. This will create active session with Okta and redirect your user to your app or redirect uri.
Cookie token is obtained via series of two calls. Authentication that gives you session token in response. Session token is exchanged for cookie token via create session call.

Suppose that I have a mobile app with a frontend and a backend server.
My understanding is that -- when a user logs in the app with "Login with google", the frontend sends a request to the google auth server, and gets back an ID token. The documentation says that the frontend can then send the token to the backend server to establish a session. I imagine that means the token can be used in session-based authentication?
If I were to use token-based authentication (as opposed to session-based), do I just attach the ID token in every server request, and have the backend verifies it each time when processing a request? this page suggests the ID token should not be sent to the backend API. Which leaves me wonder what the correct procedure is for token-based authentication when using log in with Google.
So my question is: Does my server need to create an access token from the ID token from Google, and send it to the frontend, so the frontend can attach that access token in the API requests for authentication?
Thanks
Login with Google is an identity provider (IDP) operation. A full OAuth solution, including an authorization server (AS) looks like this:
Mobile app uses system browser to redirect to AS
AS returns a redirect response to the system browser, which routes to the IDP
User signs in at the IDP
IDP returns an authorization code to AS
AS swaps it for IDP tokens and carries out validations
AS issues a set of tokens to the app. This includes an access token (AT) with whatever scopes and claims are needed for business authorization to work.
Mobile app sends AT in API requests
API authorizes using scopes and claims from the access token
So ideally plug in an authorization server, to get this out-of-the-box behaviour. Another option is to implement your own token service, and issue your own tokens. That is less recommended though, since it requires more detailed understanding of the underlying security.
I go to my application and check if there is JWT cookie
If it is there, I parse it and start to verify if user have access to my application
If it is not there, I will redirect user to authenticate in FusionAuth
After successful login, user will be redirected back to my application
How do I specify in step 3 fusionauth id of my application?
And how do I specify that I want to redirect to my application after successful login?
I assume that fusionauth is running on fusionauth.mydomain.com and application on myapp.mydomain.com and JWT cookie will be issued in mydomain.com, so it will be visible for both.
Yes, this is possible.
In step 3, you will redirect the browser to the FusionAuth login page. Navigate to Settings --> Applications in the FusionAuth UI and click on the green view button for the application in questio.
This will bring up a dialog which will show integration information (if you're on a recent version of FusionAuth).
You'll see a link something like this:
OAuth IdP login URL: https://fusionauth.mydomain.com/oauth2/authorize?client_id=ee31103f-2fc1-4bb5-ba95-ac543693503e&response_type=code&redirect_uri={your URI here}
The client_id parameter in this case will identify your application to FusionAuth.
And how do I specify that I want to redirect to my application after successful login?
This is configured in FusionAuth as an authorized redirect, and then you specify this same URL when redirecting to FusionAuth to login. Notice the redirect_uri parameter in the example URL above. There is a screenshot of this configuration here: https://fusionauth.io/docs/v1/tech/oauth/overview
I assume that fusionauth is running on fusionauth.mydomain.com and application on myapp.mydomain.com and JWT cookie will be issued in mydomain.com, so it will be visible for both.
FusionAuth does not currently drop cross domain cookies. If you are running FusionAuth at fusionauth.mydomain.com the Cookie will have that same domain and not be visible to myapp.mydomain.com.
If you want to leverage FusionAuth, then you do not need to inspect the cookie on myapp.mydomain.com, you'll simply redirect the user if they are not logged in and then if the user already has a SSO session on FusionAuth, they will be seamlessly redirected back to your application.
You can review our login workflows to identify the one that fits your requirements the best and then follow the recommended workflow. https://fusionauth.io/articles/logins/types-of-logins-authentication-workflows
This appears to be a standard OAuth Authorization Code Grant workflow. We have this workflow and many others documented here:
https://fusionauth.io/articles/logins/types-of-logins-authentication-workflows
My guess is that your specific workflow is likely the Authorization Code Grant for Single-Page Applications using JWTs and Refresh Tokens that is documented here:
https://fusionauth.io/articles/logins/spa/oauth-authorization-code-grant-jwts-refresh-tokens-cookies
The way that this works is that you start the OAuth workflow from your application by redirecting the browser to FusionAuth's /oauth2/authorize endpoint. You will need to supply this information to start the OAuth workflow:
client_id - this can be found under the Application configuration in FusionAuth
response_type - for the Authorization Code grant, this will be code
redirect_uri - this is the location you want the user to return to after they log in with FusionAuth. You must configure this URI in FusionAuth under the Application's OAuth configuration tab.
If you are running FusionAuth 1.6.0 or newer, you can also click the "View" icon for your Application and it will display a pop-up dialog that will contain the OAuth URL. You will still need to specify the redirect_uri though. Here is the documentation page for the Authorize endpoint:
https://fusionauth.io/docs/v1/tech/oauth/endpoints#authorize
Once you have that working, you will need to write the Controller for your redirect_uri. This Controller will take the code from the URL that FusionAuth generates and call the /oauth2/token endpoint. This process will exchange the authorization code for an access token, which is a JWT.
The documentation for the /oauth2/otken endpoint is located there:
https://fusionauth.io/docs/v1/tech/oauth/endpoints#token
This will help you implement your Controller.
I'm developing an Enterprise/Internet Application with WebAPI 2 RESTful server and SPA web client (Angular2) —So I have two separated projects created using ASP.NET 4.6 Empty template and both use OWIN and are IIS hosted.
The requirement for Authentication is:
Active Directory user which is logged in to the workstation will authenticated automatically once she opens any page from app in the browser if user id/name found in the database, with no need to enter her user/pass. Let name this as auto-login. Else if it's not found in the DB it will redirected to the login page.
Also there should be a logout option which redirects user to the login page after logging she out.
In the login page any AD user can enter her/his AD user&pass and after successful check against database (existed) and AD (valid credential) she/he will logged in to the system (Obviously it may be different than user currently is logged in to the workstation)
In addition to the web client it will have other clients such mobile apps which will connect and be served by the WebAPI back-end. Users will login there using their AD user & pass too. Let name it manual-login.
According to the REST architecture and having both AD enterprise and internet/mobile users together, the authentication should be token based —this is what I found till now but I'm not sure.
I read about OWIN Authentication architecture and Windows Authentication and I checked MixedAuth, Now I think it is the nearest solution for this requirement as it lets app-defined users to authenticate side by side of windows/AD users. But even after dig into it and its SPA sample I didn't found my way yet and confused.
Anyone can help?
What should I actually do on the WebApi server and SPA Client to accomplish those authentication requirements?
Which middlewares should I add and how should config/manipulate them?
UseCookieAuthentication ?
UseExternalSignInCookie ?
UseOAuthBearerTokens ?
Can I rely just on Bearer tokens (using OAuthBearerTokens MW) and get same token for authenticated windows users to unify authentication model based on bearer tokens? If so, how?
How and where should I put my code for checking that AD user exists in the DB and if not so reject the authentication?
Thanks a lot.
I need to implement an authentication mechanism with JWT tokens for an mvc web application and a mobile application as well. Users will be able to register to our database and authenticate by using credentials (from signup) or use facebook single sign on. Both applications will use web API for data exchange with JWT token. I am thinking of using Identity Server 3 for that using Resource Owner Flow and i have some questions on that:
1) User will login from mobile application and will get a jwt token. Mobile application will verify it's validity and will refresh when needed. In order for mobile application to have user always logged in should i store refresh_token on device??? Is it secure?
2) I cannot understand how am i going to handle facebook authentication and get jwt token from identity server. Should i first get users email from facebook profile data and then what???
Thank you
1- You can store refresh token in database( identity server provide a token stor)
also you can use third party library to store tokens in device securely.
2-To use the 3rd party logins you need to do the redirect style to the IdSvr login page. Using resource owner password flow means you miss out on all the features in the token service like SSO, 2fa and federated authentication.
Basically I just want to know how does StackExchange's single signon system work?
In the SE network you need to login only once in one of the websites to be automatically logged in to the other sites upon visiting.
How should I implement such a feature in my own network of sites?
I assume it uses the cookie which resides on the user's browser and then authenticates it with the originating site. If it is legit then it logs the user in automatically.
You have to implement SAML or oauth2 to allow sso on your network.
In case of SAML your child websites will be service providers or resource servers.
While you need to setup and identity provider.
The sequence of events will be like this.
1. User hits a url of songs website, this site is resource server and does not handle authentication.
2.To authenticate resource server will construct a SAML authrequest and redirects to identity provider after signing it.
Idp verifies the signature after receiving authrequest.
3. User will be presented with a login form, user has to end login credentials.
4. After user authentication idp will generate a SAMl token and redirect back to resource server.
5. Resource server will extract identity information from SAML token, resource server will login the user with session or cookie.
Depends upon which technology you are working in i have implemented it in php using simplesamlphp.
