Vaultwarden Build Version

v1.35.0

Deployment method

Official Container Image

Custom deployment method

No response

Reverse Proxy

nginx

Host/Server Operating System

Linux

Operating System Version

NixOS 25.11

Clients

Client Version

No response

Steps To Reproduce

Go to your vault’s login page
Try to log in with SSO

Expected Result

I should be logged in

Actual Result

Kanidm complains about the redirect uri (https://your.domain//identity/connect/oidc-signin not being an exact match of https://your.domain/identity/connect/oidc-signin and therefore rejects the login attempt.

Logs

Screenshots or Videos

No response

Additional Context

It works when I add https://your.domain//identity/connect/oidc-signin as redirect uri but I don’t think that’s the right way here.
