Vaultwarden Build Version

v1.34.3-8e7eeab2

Deployment method

Official Container Image

Custom deployment method

No response

Reverse Proxy

Caddy v2.10.0

Host/Server Operating System

Linux

Operating System Version

No response

Clients

Web Vault

Client Version

No response

Steps To Reproduce

Run vaultwarden on a subpath on the domain like https://vault.domain.com/my/vault/
Configure SSO according the Wiki, specifically the redirect url in the SSO provider (mine is Authentik) to:

https://vault.domain.com/my/vault/identity/connect/oidc-signin

Expected Result

SSO Authentication flow should work, meaning you get the login page from SSO provider and follow the steps there until authentikated.

Actual Result

Authentik flow aborts with the error incorrect or missing redirect_url

Logs

Screenshots or Videos

No response

Additional Context

I changed my setup so that vaultwarden runs on the domain root e.g. https://vault.domain.com/
I adopted the redirect url in Authentik to: https://vault.domain.com/identity/connect/oidc-signin
Authentikation now works without any further changes but these two above

Note: i did not change anything on my Reverse Proxy, it just reverse proxies anything to upstream

I would really keep the security-by-obscurity/in-depth-security benefit of running vaultwarden on a path on my subdomain. Others will probably even depend on this if only one subdomain is available
