I added support for SAML 2.0 SSO with Okta to my application using Kentor AuthServices .NET package and the first action done by a user is clicking "Login with Okta" button and then being redirected to Okta's sign in page with SAML request token generated by Kentor.
In some scenarios the user email (username in Okta) is already known beforehand and I want to pre-populate the Username textbox on Okta's sign in page with this value.
Is it possible to do that, for example by providing the desired username in SAML request or in the cookies?
The SAML standard has support for including a Subject (that is a user name in SAML lingo) in the AuthnRequest. Unfortunately Kentor.AuthServices doesn't support that (yet). There has been some work done (see https://github.com/KentorIT/authservices/issues/430) but I don't know the current status.
Then you of course need to check whether Okta supports reading that data.

I am trying to integrate OKTA as service provider to provide access to the custom application for external customers.
External Users login to enterprise Idp to access the custom application
After successful authentication IDP triggers the IDP-Initiated flow and submits the SAML response to OKTA
OKTA checks for the external user information in the SAML assertion and sends these details to Custom API application to identify the user
If the user is found, the API returns the required information to OKTA
OKTA will initiate the PKCE flow to provide access to the custom application
I was success in configuring the OKTA and external customer IDP. But, Can anyone knows how OKTA will call the custom API application to identify the user information? Also, how to configure the redirect URL?
unfortunately I don't have an answer to your question as we use PingFederate but I was curious as to how you setup Okta (as the SP) to accommodate the IdP-Initiated call, without having to call back into the IdP for authentication? I ask because, as the IdP, we are calling Okta (as the SP) and the SAML response but the vendor is stating they cannot setup Okta without the IdP URL to call back into to have us, the IdP, authenticate the user. Seems your setup works how we believe it should so wanted to get more details about this.
I need to implement SAML SSO in a webb site based on web forms, can someone please show a example of how to that?
You need a SAML stack on your client.
Some of the commercial clients have examples of this.
Basically:
Configure the client-side SAML parameters based on your IDP
Have a form with a Login button
When the button is clicked, use the stack to send an AuthnRequest
This will trigger an IDP login form
After the user has logged in, the IDP will return to your Assertion Consumer Endpoint with the SAML token
Use the stack to extract the attributes you need
I have a portal application developed using spring security and mvc framework. This portal application connects to IDP (Developed using Spring security and spring saml) for authentication. if the user authentication is success,user will be navigated to homepage where multiple links are provided for external applications… When the user clicks on the application link, user should successfully navigated to the respective application without challenging login page.
Other applications are developed using struts and spring security. How do I make sure that when a link is clicked from the portal, either saml token or context is passed to other application so it will not ask for login.
Any help is greatly appreciated.
The most common flow for SAML is something like the following:
Application (called service provider, or SP) receives request (any request, like request for a business resource) from unauthenticated user
It redirects the user (most commonly via http redirect) to the IdP (in which the SP should already be registered)
If the user is not authenticated to the IdP (not logged in to SSO), a login form is presented and login is managed by the IdP until there is a user session with the IdP
If the user is already authenticated with the IdP (because either he was already or entered a correct user/password), the IdP issues its claim token and posts the user with the token back to the Assertion Consumer Service in the SP (the original application)
The Assertion Consumer Service (practically just an API endpoint) receives and validates the SAML token and creates an own application session with the user. Now the user is authenticated to the application (SP)
Upon the next request to the application (SP), there is already a session, so SAML is not involved
Note that if there is already a session with the IdP, all of this is seamless for the user. A bunch of redirects take place, but the user will just reach the application without entering credentials.
So the short answer to your question is that your external applications need to support SAML SSO and need to be registered with the identity provider, in which case they can just use the IdP for authenticating the user and signing the claims it may have.
I am trying to implement a OAuth2 Provider, that authenticates users with a custom login.
For understanding I looked at the Spring Boot OAuth2 Tutorial.
I don't quite get, how I can implement my own Authentication meachnism to work with the OAuth2 SSO from my Server.
I want to add custom authentication mechanisms (like "user has to answer a question for authentication" or "user has to enter id and click button for authentication") instead of the Facebook and Github examples.
I read about implementing my own AuthenticationProvider, but I am stuck how to combine all the puzzle parts.
Let's go one step at a time. OAuth is only authz provider so not talk about authentication. Now for your usecase specifically, if you want user to be authenticated then OAuth authz code based flow makes sense (You can even go for implicit flow, check rfc 6749). Now how will this work for you. I am picking up the implicit flow for simplicity, Authz flow is just extension of it where end client gets a temporary code which it exchanges with Identity Server later to get the access token. Here are the steps:
Client App hits the /authorization uri with data as per rfc 6749
After validating the submitted data, server forwards user to Login page (or other page for authentication). After authentication, cookie is set in the browser or data is stored in server to mark a user as authenticated.
After authentication server redirects user to user consent page (You can even skip this if needed depending on need, But OAuth 2 spec contains this) where user specifies which all permissions (scopes) are allowed, here user can allow either allow or deny.
if user allows then these permissions are submitted to server and then server stores the data and redirects the user to client URI with access token in # fragement of client redirect URI (callback URI submitted during actual request)
I am trying to implement SAML SSO between two J2ee applications (form-based) deployed on two different instances of WAS, I have configured both WAS instances as service providers using the steps in http://pic.dhe.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=%2Fcom.ibm.websphere.nd.multiplatform.doc%2Finfo%2Fae%2Fae%2Ftwbs_enablesamlsso.html
I set the property sso_1.sp.login.error.page to the login page of the Identity provider but when I get redirected to the login page, it displays that no SAML request (AuthRequest) is available, can anyone tell me why the WAS is not issuing the SAML authentication request?
WAS does not send a SAML request in the redirect. This is explained in the paragraph above this section of the DeveloperWorks SAML TAI article. The scenario you're expecting is referred to as the solicited response. WAS only supports what the article terms the unsolicited response. In this latter case, the IDP must understand how to authenticate the user (usually through a browser interaction) without a SAML request.
