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

Fri Aug 17 11:40:33 EDT 2018

Suleyman, thanks for the clarifications,

So in your Keycloak you've got two clients: one OIDC and one SAML, and a SAML IdP (ADFS).
Do you want IdP-initiated SSO from ADFS to both clients? or is it only OIDC one (https-client)?

I think it is IDP initiated SSO. He wrote his credentials on login page of MS ADFS clicked sign in. I am redirected to Keycloak IDP https://urldefense.proofpoint.com/v2/url?u=https-3A__myapplication_auth_realms_springboot-2Dquickstart_broker_myIDPAlias_endpoint&d=DwIFaQ&c=eIGjsITfXP_y-DLLX0uEHXJvU8nOHrUK8IrwNKOtkVU&r=W6co1eMBjqBh4emCmcok5fidBI1eOf715bxeMRmm3-g&m=67Jdm10z1uM35jlf76_8hLfYG6Jw218kWhrnGkaevNE&s=0BKswkj_bBt6d0dMqEKurFsuBL0tilkKtemQvb00vYQ&e= and get the Internal Server Error again* but with different error (attached file). I wonder if I need to change any Keycloak settings to enable that.

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?

As for real ADFS integration, I setup everything according to that blog https://urldefense.proofpoint.com/v2/url?u=http-3A__blog.keycloak.org_2017_03_how-2Dto-2Dsetup-2Dms-2Dad-2Dfs-2D30-2Das-2Dbrokered.html&d=DwIDaQ&c=eIGjsITfXP_y-DLLX0uEHXJvU8nOHrUK8IrwNKOtkVU&r=W6co1eMBjqBh4emCmcok5fidBI1eOf715bxeMRmm3-g&m=-8fNnCezquRNyr7Io0tF57v6RXFvwaZ-DKyKnOYEQyo&s=X9S93qI_kOVUhIWAq4qzd6DkJBfFb5lVIIiFzin9ixg&e= 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.
