Authentication in Proxy Provider broken after upgrading to 2025.10 #17805
Description
Description:
After upgrading Authentik from 2025.8 to 2025.10, HTTP authentication in the Proxy Provider no longer works. Requests that previously passed through authentication now ignorieren.
Steps to reproduce:
1. Upgrade Authentik from 2025.8 → 2025.10.
2. Configure a Proxy Provider with HTTP authentication enabled.
3. Make a request that should be authenticated via the Proxy Provider (HTTP Basic Authentication)
5. Observe that authentication fails — the request is rejected or prompts for credentials.
Expected behavior:
• HTTP authentication through the Proxy Provider should function as it did in 2025.8.
• Requests with valid credentials should pass through successfully.
Actual behavior:
• Authentication fails consistently for all requests.
• No relevant error messages in Authentik logs indicating configuration issues.
Additional information / Notes:
• No other major configuration changes were made aside from the Authentik upgrade.
• Downgrading back to 2025.8 restores HTTP authentication functionality (Rolling back a ZFS Snapshot).
