Re: [keycloak-user] [External] Re: IDP SAML Processing Error

Hi Dmitry, I have been struggling for many days for that😊 I have two clients and a IDP broker in Keycloak. > https-client: Yes, this is the client that secured the application. > Redirect urls point to our application (https://urldefense.proofpoint.com/v2/url?u=http-3A__myapplication-3A8443&... application).It is "resource" : "https-client" in Keycloak.json in AngularJS. saml client: sends SAML request via IDP broker IDP broker: deals with MS ADFS requests/responses Regards, Suleyman -----Original Message----- > From: Dmitry Telegin <dt(a)acutus.pro&gt; Sent: 17 August 2018 15:24 > To: Yildirim, Suleyman <suleyman.yildirim(a)accenture.com>; > keycloak-user(a)lists.jboss.org Subject: Re: [External] Re: [keycloak-user] IDP SAML Processing Error Hi Suleyman, you're welcome :) Glad your SP-initiated SSO finally worked. As for IdP-initiated SSO, this is also a well-known situation. In a few words, it will work out of the box *only* if you Keycloak client (target application) is also using SAML. You mentioned some "https-client(open_id)", does that mean that the application is secured by Keycloak OpenID Connect adapter? (Don't despair, there is a workaround nevertheless.)

I think it is IDP initiated SSO. He wrote his credentials on login page of MS ADFS clicked sign in.

After authentication, the Identity Provider generates an XML authentication response document, which contains a SAML assertion that holds metadata about the user like name and email.

The route cause of the error is Caused by: java.io.IOException: Short read of DER length. So I suspect that Validating X509 Certificates input box doesn't work as expected in Keycloak: "Certificates must be in PEM format and multiple certificates can be entered by comma (,) ". I have to use Public key and the certificates of the realm separated by comma but I get 500 - Internal Server Error from MS ADFS server and the  error in Keycloak (Attached file: IDP_error.txt). If I only use realm certificate, I get invalid requester error. Any idea of how I can proceed? > > > > Details > > > > When I use dummy IDP of Keycloak server, I use https://urldefense.proofpoint.com/v2/url?u=https-3A__myapplicationurl_aut... as SSO url, "email" as "NameID Policy Format" (Attached file: dummyIDPSettings.png). As for real ADFS integration, I setup everything according to that blog https://urldefense.proofpoint.com/v2/url?u=http-3A__blog.keycloak.org_201... and use the client's SSO url (Attached file: ADFSIDPSettings.png). I think I did everything right. Keycloak endpoints, SSL keystore and truststore files are at the right locations and places. > > > > Regards, > > Suleyman > > > > > > ________________________________ > > > > This message is for the designated recipient only and may contain privileged, proprietary, or otherwise confidential information.
