Keycloak version 21 saml integration

[lamenawuer]

Hello ,

I'm migration an old version 4 Keycloak client that connected with cbioportal with saml into a version 21 one and I can't make it work. I'm getting this error stack in the logs:

My v21 keycloak client settings:

• fore post binding: off
• force artifact binding: off
• include authstatement: on
• include onetimeuse condition: off
• optimize redirect: off
• sign documents: on
• sign assertions: off
• signature algo: rsa_sha256
• saml signature key_: key_id
• canonicalization method: exclusive

My saml settings for cbioportal:

Could someone please give me a hand?

Thanks a lot

@lamenawuer thanks for reaching out! I don't think cBioPortal works with keycloak v21 yet unfortunately. I filed a separate ticket for enabling v22 support: cBioPortal/cbioportal#10360. Is it possible for you to use an older version of keycloak for now? Thanks!

Hello, thanks for answering, no unfortunately I am unable to downgrade my keycloak version...
