Check Existing Issues

  • I have searched the existing issues and discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

v0.6.26

Ollama Version (if applicable)

No response

Operating System

Oracle Linux 9.4

Browser (if applicable)

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

User is expected to login via Keycloak OpenID Connect single sign-on. Previously we had this working on v0.6.15

Actual Behavior

The user cannot login via Keycloak OpenID Connect single sign-on on v0.6.26. Browser is showing: {"detail":"The email or password provided is incorrect. Please check for typos and try logging in again."}

On the backend docker logs it shows: 2025-09-01 09:50:55.593 | WARNING | open_webui.utils.oauth:handle_callback:361 - OAuth callback error: Invalid JSON Web Key Set

Steps to Reproduce

Login with Keycloak OpenID Connect SSO configured. The same configuration worked on v0.6.15, but not working on v0.6.26.

Relevant environment variables used:
- ENABLE_OAUTH_SIGNUP=True
- ENABLE_LOGIN_FORM=False
- OAUTH_MERGE_ACCOUNTS_BY_EMAIL=True
- OAUTH_CLIENT_ID=openwebui-qa
- OAUTH_CLIENT_SECRET=xxxx
- OPENID_PROVIDER_URL=https://sso.ubrmbqa.com/auth/realms/ubrmbtest/.well-known/openid-configuration
- OAUTH_PROVIDER_NAME=xxxx
- OAUTH_USERNAME_CLAIM=preferred_username
- OAUTH_EMAIL_CLAIM=email
- ENABLE_OAUTH_ROLE_MANAGEMENT=True
- OAUTH_ROLES_CLAIM=roles
- OAUTH_ALLOWED_ROLES=user
- OAUTH_ADMIN_ROLES=admin

Logs & Screenshots

I am attaching browser HAR and docker logs.
