Feature Summary

Logging in using OIDC is successful when RS256 is set on the IDP (keycloak in my case), but unsuccessful when PS256 or EdDSA is set.

"Use EdDSA where possible and use ECDSA when it is not. If you are forced to use RSA, prefer RSASSA-PSS [PS256] over RSASSA-PKCS1-v1_5 [RS256]" (quoted from “JWTs: Which Signing Algorithm Should I Use?”).

Steps to reproduce

  • Set PS256 or EdDSA as the signature algorithm on the IDP side such as keycloak
  • configure OIDC settings on AWX pointing to that IDP
  • login with OIDC

Current results

Login is unsuccessful

stronger security

Additional information

  • OpenBanking has already made the transition to PS256 since 03/2019
  • Australian infosec has a requirement for PS256 since 2019

Research direction
The issue requests adding support for PS256 and EdDSA JWT signature algorithms in AWX's OIDC authentication flow. To implement, locate the OIDC backend code, likely in files handling JWT verification (e.g., awx/sso/ or similar). Investigate the current algorithm support and extend it to include PS256 and EdDSA. Review linked resources like the Scott Brady article for guidance. Ensure compliance with existing authentication tests.
