We are about to integrate our JAVA application with SSO Federation. We will get a metadata in SAML2 Assertion format and all the session tracking is taken care by SSO federation.
I am not clear how the session tracking happens with each request in our JAVA application. Our main page URL is configured in the SSO federation and after user clicks the link control comes to our application. So if I navigate to other URL apart from the one configured, how the federation track the session? Do we need to pass any metadata for each and every request?
We have been asked to share the home page URL and certificate information and SSO federation will configure those in their portal.
A Java application server normally trackes a user session using a 'JSESSIONID' cookie. Once the SAML assertion generated by an IDP(say ADFS) has been validated by the SP(the java application here) a security context /session is created which is identified by a JSESSIONID. The browser sends JSESSIONID cookie with seubsquest requests and the application verifies it and servers the requetsed resource/URL.

I have next components:
RP-1 (connected by Ws-Fed, WIF)
RP-2 (connected by SAML, Federation Provider, actially it is another ADFS)
MY-ADFS (ADFS Server 2019 as primary STS)
MY-IP (separate Identity Provider web service, Identity Server 4)
Thus, when I make a sing-out request from RP-1(Ws-Fed), a simple Ws-Fed Logout is formed a request to ADFS:
GET https:/MY-ADFS/adfs/ls/
wtrealm: https://RP-1.com/
wa: wsignout1.0
wreply: https://RP-1.com/logout/
Next ADFS makes redirect to IP:
GET https://MY-IP/WsFederation
wa: wsignout1.0
wreply: https://MY-ADFS/adfs/ls/?redirectContextId=2dd581d2-6e02-4476-915b-a581e3c855d4
thus the user clears the session from ADFS and from IP. - as expected.
However, if before the logout, the transition to SAML RP was made and the SAML session became active, then upon exiting ADFS gives an error:
MSIS7055: Not all SAML session participants logged out properly. It is
recommended to close your browser.
To fix it, I configured the logout endpoint (URL) in the SAML relying party trust as:
https:/RP-2/adfs/ls/?wa=wsignout1.0
With POST binding. After these changes, the error disappeared. But now ADFS no longer does make Logout redirec to to IP, but instead it does a SAML Logout redirect to RP-2:
POST https://RP-2/adfs/ls/?wa=wsignout1.0
SAMLRequest: PHNhbWxwOkxvZ291dFJl
And as a result, Instead of switching to IP, I remain on the RP-2(ADFS also) page where it is written that the exit was successful. However, the user still has an active session (cookies) on the IP side.
Several questions here:
It is not clear why ADFS changes the chain of calls with the SAML active session.
It is not clear how to exclude SAML Logout redirects, or force ADFS to make Logout to IP also.
You will have to add the logout URL in the IP (Identity provider) side as well to ensure that the SAML token generated by signing out from the SaaS application through ADFS is forwarded to the Identity provider and is updated for logout at IP authorization provider end. So that, the cookie on the browser will be updated and sign out will be processed smoothly.
Please find the below probable steps to update the logout URL at the Identity Provider end: -
Open the authentication provider workspace.
Find the logout URL.
Update the URL to the ‘https://RP-2/adfs/ls/?wa=wsignout1.0’ same as that configured in ADFS Server.
Save your changes.
And as for your first query why ADFS changes the chain of calls with SAML active session, it is because the cookies and cache must be removed from the system for successful logout request, thus the logout time as recorded when signing out is updated at the SaaS app end and thus, it is recommended to close the browser let it update in the system also.
Thus, recommend you open both the RP trust apps in different browser windows as both are configured for different token providers.
Please refer the below thread for more information: -
How do you handle the logout process for applications federated with ADFS?
Thanking you,
I have a external openidconnect identity provider registered with Keycloak. When the client app tries to access the protected resource it gets redirected to KeyCloak login page. On the login page I have the external openidconnect provider buttons enabled. Once the user clicks on the button he is taken to the external identity provider (which is identityserver3 instance). The external provider does authenticate the user and send back a code.
Now the redirecturl for the registered client in the external identity provider is that of keycloak's. So after authentication is successful at the external IDP it send back the code(because it is Auth code flow) to keycloak at a redirect url:
http://localhost:5555/auth/realms/QA/broker/keycloak-client/endpoint?code=7bcf5157105199d50874e64eabf03858&state=wQhNIEKW0Ws6CotZg2EsvOorjDVQlWVvobcM2skPSXo.keycloak-client&session_state=rhgu-BXT8FniG9Z-UARKpp_f-V1nLN-VxFmSE3PSxDg.99b2d903367208e4261fefa475afb1eb
In the URL if you see it ends with endpoint. I don't think that's correct but I cannot change it in KeyCloak (it's disabled) and because of that in the external IDP client configuration.
KeyCloak does not understand above url and errors out with a message "unexpected error when authenticating with Identity Provider"
Isn't KeyCloak supposed to understand the code flow and make another request for token after receiving the code. Then the external IDP will respond with token and Keycloak will send back that token to client(will also store it for future use).
Can someone please share some knowledge on how Keycloak works with external openidconnect ID provider with code flow.
Usually the redirect URI for external identity providers take the form of {keycloak-host}/auth/realms/{realm}/broker/{provider}/endpoint. You have to specify this as the redirect URI when you register your client in the external identity provider. Once the user is authenticated through the external IdP, authorization code will be sent to this url, which in turn will redirect it to the redirect url of your client application (specified when registering the client in Keycloak).
Unexpected error when authenticating with Identity Provider is the general error message sent by Keycloak for several errors that occur during the OAuth flow. You won't be able to determine the actual cause without going through the stack trace or the logs in the prompt.
You are getting this error because keyclaok is unable to get token from identityserver3 by exchanging authorization code. Where did you hosted identityserver3? Does it have a real ca certificate or you are using self sign certificate? Have you configured client_id , secret, token endpoint properly in keycloak external IDP configuration? You can test manually my posting client_id, secret, code (that you received) in token endpoint of identityserver3.
I have a Java app running under Websphere Liberty on IBM Bluemix. I need to be able to authenticate users 3 different ways - Basic Auth, SAML SSO, and OpenAuth SSO, in that order.
I can set up the app to do Basic Auth (using custom code) or SAML SSO (using the Bluemix Single Sign On service), but can't figure out a way to configure it to handle both at once. (I haven't even looked into how to do OpenAuth yet.) If I configure the app to use the Bluemix SSO service, then my app never sees the incoming requests to check for a userid and password to try Basic Auth before the SSO service grabs it.
I tried changing the redirect URL in the SSO service to an endpoint inside my app, but then all I get is
CWOAU0062E: The OAuth service provider could not redirect the request because the redirect URI was not valid. Contact your system administrator to resolve the problem.
I can't be the only one that needs to do this. Can anyone tell me how they did it?
I've just configured Shibboleth IdP3.2 with my web application that authenticates the users against an LDAP server at the backend.
I could test this authentication process at the local machine. But, while deploying the code on CI server, I realized that the authentication process could not be completed successfully.
The reason behind this failure is that the Service Provider (SP) cannot access the (IdP). From our initial investigation, We chose SAML as the authentication protocol over other protocols like CAS because it did not need a back channel communication. As long as the user has access to both SP and IdP,the authentication process would still work.(SP and IdP need not interact with each other)
On testing we found that the attribute resolution is successful, but the subsequent artifact resolution is failing. In artifact resolution, IdP directly contacts the SP and expects a response. SP cannot send a response to IdP as it is inaccessible. Hence, the authentication fails. (Tomcat logs show: unknownHostException)
Some SAML flows in Web Browser SSO do not require direct communication between SP and IdP as seen from flow diagram in this link.
Does Shibboleth IdP make provisions for such implementations? Is there a work around for implementing Shibboleth IdP without any back channel communication?
SOLUTION:
As Stefan mentioned, there are alternative bindings like HTTP-Redirect and HTTP-POST that do not use back channel communication. You can read more about these bindings here
I changed the SP metadata to make HTTP-POST as the default binding, referring this link.
I did not have to make any changes to Shibboleth IdP configuration as these alternative bindings were already being supported, as substantiated by the metadata file.
According to this documentation, you can set the outgoingBindings attribute to set the preferred binding to use.
I would also recommend removing the HTTP-Artifact binding from the SP metadata.
We are starting a project for SSO and using wso2 to do all SAML , OAuth and keep our Webapplications as service providers.
I have been through the online documentation but need some help .
When user tries to Access to any resource in our webapplication i would send user to wso2 to get Authenticated in case of OAuth /openid connect , how would i form this url ?
I have configured IDP and SP in WSO2 console, after authentication how does WSO2 give credentials of authenticated users to service provider , i see as per document or sample app , this should be SAML or any other sso protocols like oauth etc. documentation is not clear or any examples i can find
i want to redirect the user after OAuth or SAML with my own created Authn cookie , what is the provision for that .
any help would be appreciated
Yes, You can configure your application as service providers and wso2 IS as Identity provider.I guess, You can implement saml sso for your scenario and its simply documented here.There is another blog which describe the same configuration
You can download travelocity sample code and war file .Analysing the code you can get some idea about implementation.
By following above blogs, You can implement the complete SSO flow.
Q. > When user tries to Access to any resource in our webapplication i would send user to wso2 to get Authenticated in case of OAuth /openid connect , how would i form this url ?
Answer :
https://localhost:9443/oauth2/authorize?response_type=code&client_id=wCmphfs69oaN3JhqO3d9FFgsNCMa&scope=openid&redirect_uri=http://localhost:8080/Samplespapp/googleauth.jsp
client_id : is that if which we get on UI oof wso2 console after we finish configuring Service provider in my case i configured Inbound Authentication Configuration as OAuth open id .
redirect_uri is the url where we want to go after authentication , this should match callbackback url in View/Update application settings
Answer 2: I still dont see any valid reason why inbound authentication has to be sso protocol but this is how wso2 works , to put it in laymans term i have a client to connect to using SAML and Other OAuth . i opt for a SSO vendor who takes that headache from me to implement SSO protocols but i Still have to implement atleast one SSO protocol as after SSO handshake wso2 has to communicate userX with role as Admin to service provider app this is done again using SSO !!
ping federate makes it simple it makes an encrypted request header that had data in key value pair. may be i am not understanding but i dont like this inbound Authentication in SSO .
Q. 3.>i want to redirect the user after OAuth or SAML with my own created Authn cookie , what is the provision for that
documentation is poor in this area just some java classes but no end to end example , every one will point to travelocity .
