I have an angular webapp that communicates with a java backend through rest services.
This webapp has a login screen linked to a user table.
Now I should link this webapp with a company's ADFS service to implement SSO.
The company only provided me with federationmetadata.xml
What is the best procedure to make this connection?
NB: ADFS must pass me email and group, to login in my webapp and then show certain contents based on the role of the user.
Thank you

I am using Cognito in AWS. There are no users in the Cognito User-Pool, instead of this it is connected to a federated IDP through OpenId Connect. The federated IDP is an Microsoft ADFS.
I have another application, which is using the Cognito OpenId Connect solution for securing an web Application.
The User access the Web Applikation, is beeing redirected to the IDP Login page. He authenticates against the federated IDP, gets back to the Website and is logged in there.
Everything is fine in this scenario.
The same web application offers a REST Api, too. With this connection I have some trouble. There is no human user who is consuming this API, but I have a service account created in ADFS.
First of all I need to get the access code:
https://demo-cognito-trg.auth.eu-central-1.amazoncognito.com/oauth2/authorize?response_type=code&client_id=1************q&redirect_uri=https://my-redirect-domain/management&state=STATE&scope=openid+profile+email
From that URL I can get the authorization code and use this to get an access_token from the oauth2/token endpoint. But when I do a GET on this ressource, I get a webpage where I need to authenticate myself.
What call do I need to perform so that I can use f.e basic auth to signin my service user?
My apologies for my bad english.
I have the tool Apereo CAS using as login SSO. When i'm using with application statefuls this works very well. But i wanna call a API REST (stateless) for specific scenario and validate the logged user (and using your informations on the service). My backend API is developed with Spring Boot. Someone needed a similar situation?
Ps: This API will acess by frontend and services without frontend therefore I'll not be able to use cookies.

Thank's.
Your front-end application needs to ask the CAS server for proxy authentication.
One of the more common use cases of proxy authentication is the ability to obtain a ticket for a back-end [REST-based] service that is also protected by CAS. The scenario usually is:
User is faced with application A which is protected by CAS.
Application A on the backend needs to contact a service S to produce data.
Service S itself is protected by CAS itself.
Because frontend contacts service in the back-end via a server-to-service method where no browser is involved, the backend would not be able to recognize that an SSO session already exists. In these cases, front-end needs to exercise proxying in order to obtain a proxy ticket for the backend. The proxy ticket is passed to the relevant endpoint of the backend so it can retrieve and validate it via CAS and finally produce a response.
The trace route may look like this:
Browser navigates to front-end.
Front-end redirects to CAS.
CAS authenticates and redirects back to front-end with an ST.
Front-end attempts to validate the ST, and asks for a PGT.
CAS confirms ST validation, and issues a proxy-granting ticket PGT.
Front-end asks CAS to produce a PT for back-end API, supplying the PGT in its request.
CAS produces a PT for backend API.
Front-end contacts the service S endpoint, passing along PT in the request.
backend API attempts to validate the PT via CAS.
CAS validates the PT and produces a successful response.
Backend API receives the response, and produces data for front-end.
A receives and displays the data in the browser.
See this for details.
My web app need to authenticate with ADFS for single sign on (SSO). Which mean if user is already login to ADFS, when user access web app, web app need to verify if the user is already login to ADFS. If yes then redirect user to page 1, else page 2. I am using java-saml from (https://github.com/mguessan/java-saml). Is it possible to verify if the user is already login to ADFS?
Looking at https://github.com/mguessan/java-saml, it seems it does not provide a Servlet Filter implementation, like e.g. Spring Security SAML implementation or other toolkit are doing it.
If you always want to do SSO (and do not want to provide a local login),
it might be best to create a filter on your own and directly trigger so called SP-initiated SSO flow to ADFS based SAML IdP. Just have a look at https://github.com/mguessan/java-saml/blob/master/samples/java-saml-tookit-jspsample/src/main/webapp/dologin.jsp
We are implementing a soap client in Java (using cxf wsdl2java). In previous projects the authentication has been based on either WS-Security or Basic HTTP Authentication. These are both easy to test in SoapUI and implement in java.
This time however, the server uses a Web Application Proxy which works as a reverse proxy, and ADFS (Active Directory Federation Services) for authentication purpose. I don't know the details of what this means, but what happens when opening the wsdl endpoint URL in a browser is that we get redirected to a login page similar to the office login page https://login.microsoftonline.com/ where you have manually click on the account type before entering credentials.
When logging in manually, we get redirected back to the wsdl endpoint with an appended ?authToken=xxx at the end and I think the token lasts for 1 hour. We have tried to ask the provider to use a more standard authentication, but for now this is the only thing we have. How do we approach this?
When trying to do a test request from SoapUI, we just get the complete html code of the login page in response. I see there is a Form Based Authentication option in SoapUI but it won't work since the login page has multiple account types and multiple username/password fields. The workaround for testing is just to login manually and use the authToken. But how can we automate this in the Java cxf client?
When connecting to the endpoint url in a browser, this is how the url looks after redirected to the login page:
[url to adfs seriver]/adfs/ls?version=1.0&action=signin&realm=urn%3AAppProxy%3Acom&appRealm=a10037ed-ca1e-e711-9436-00215a9b01ac&returnUrl=[wsdl endpoint url]&client-request-id=13A5B5A6-B574-0000-6FBA-A51374B5D201
You can't use SOAP to authenticate with ADFS via a login screen. This is because ADFS only supports WS-Fed or SAML-P or OpenID Connect (ADFS 4.0).
What you can do is use WS-Tust to do this.
WS-Fed supports two profile viz. passive (browser login screen) or active (web service / WCF). You need to use the latter.
There are a number of active profile endpoints that are available in ADFS. Not all are enabled by default so you may need to enable them.
I have a web application that makes use of spring security and authenticates users against an AD server using LDAP so we do not store the users password in our application. This all works fine.
Now my application is trying to make RESTful webservice calls to a sharepoint server which requires NTML authentication. The sharepoint server also authenticates users by doing an LDAP lookup to the same AD server.
Is there a way to avoid having to ask the user for their credentials again (somehow letting sharepoint know that the user has been authenticated with the use of a token or something?)
