We have one intranet Application and implemented ADFS authentication on it. We have our custom login form with Username and password and we are authenticated easily using ADFS. we are using windowsmixed endpoint to authenticate
Application, Users and ADFS all are in one domain
Now we want to skip that login page, so if Domain\User1 is logged in on his/her machine , intranet application should authenticated with current windows logged in user automatically without asking username and password when we open it.
Is it Possible and How?
Thanks!!!

Normally this is done via IWA in a browser (WS-Fed passive profile). IWA is a function of the browser not ADFS.
You are using WCF (WS-Fed active profile) which has no browser component.

I am using Spring Security to authenticate with SAML and Okta, generally it works, I am able to authenticate a user and access secured URLs within my application. So far so good.
Now I have a requirement for a special type of 'internal' users to use different authentication mechanism (those users will not be in AD nor Okta) - so if authentication fails using Okta I want to display different login page. Problem is that I am unable to redirect from Okta login page to my custom page after unsuccessful login, seems like Okta will not redirect even after many unsuccessful attempts.
Is there a way to implement such requirement?
You can't redirect Okta on a failed authentication. You will need to determine what type of authentication to use prior to validating the username and password. Okta supports application based custom login page and so when the user tries to access the application, Okta redirects to your login page. From there your login page will determine where to authenticate the user.
Okta configuration for custom login page
You can use Okta's Authentication APIs and SDKs to authenticate against AD and custom code.
I've been working whit the SAML extension to connect to an ADFS server. I've hacked the sample application to use my ADFS server and everything went well, but I would like to know if there is a way to connect to an IDP without using the loging page of the IDP. I mean if there is a way to do this process in background for the end-user. I am thinking about doing a query to ADFS or something like to get the users and do authentication from the SP login page, avoiding the need for the user to authenticate in the IDP login page.
The purpose of federated authentication is to delegate it to a centralized server in such a way that the relaying parties/service providers do not have access to user's credentials. Enabling authentication directly in your application would violate this principle and for this reason is not supported by neither Spring SAML nor ADFS.
If you want to authenticate your users directly, use authentication directly against Active Directory instead of ADFS. This will fully support your use-case.
I want user to be authenticated by using its windows login credentials without explicitly showing him login page. The user will just login to his machine and when we will try to open the url he will be authenticated by spring security using his windows login credentials and data related to his role will be fetched from AD. How can I achieve this?
Adding to this question, what I need to do if machine is non-window? say CentOS?
I need to check if user is authenticated in the system in a PHP application that is not a PHPCas client. Does the RubyCAS server provide API for this? How do you make secure communication in this case?
The solution to the problem is the gateway feature of the CAS protocol. This feature will redirect a user to a CAS server so that the user’s browser can be authenticated via the initial ticket-granting cookie given to it the first time the user submitted credentials. If the ticket-granting cookie is found, then the CAS server will redirect the user back to the app without having to re-enter credentials.

has anyone implemented signgle sign on in MVC? Can anyone give me any example for single sign on in MVC.
I've implemented a SSO solution between multiple ASP.NET MVC applications hosted on the same parent domain (app1.domain.com, app2.domain.com, ...) by using Forms Authentication and setting the domain property of the cookie in web.config of all applications:
<forms
name="ssoauth"
loginUrl="/login"
protection="All"
timeout="120"
requireSSL="true"
slidingExpiration="false">
domain="domain.com"
/>
When you set the domain property of the cookie, this cookie will automatically be sent by the client browser to all applications hosted on this domain and will be able to authenticated the user automatically.
If you want to implement a cross domain SSO using Forms Authentication here's what you could do:
The user navigates to foo.com and signs in. The application hosted on foo.com uses standard Forms Authentication, nothing fancy.
The user decides to go to bar.com and clicks on a link that you created. This link could contain a token parameter which will contain the encrypted username. This encryption could be done using the machine keys and look something like this: https://bar.com?token=ABC.
The application hosted on bar.com receives the request and because it uses the same machine keys as the other application it is capable of decrypting the token and fetching the username. Then it simply signs in the user by emitting an authentication cookie locally and the user is automatically signed in bar.com.
Below is an example for SSO for websites sharing same domain

Please see my answer here. Basically you need to set Authentication mode to windows on web.config and use HttpContext class to retrieve user identity which takes data from Active directory
