Vaultwarden Build Version

v1.35.1

Deployment method

Official Container Image

Custom deployment method

No response

Reverse Proxy

traefik 3.6.6

Host/Server Operating System

Linux

Operating System Version

No response

Clients

Web Vault

Client Version

No response

Steps To Reproduce

Try to authenticate using SSO (the instance if fresh)

Expected Result

Should be able to connect using my ZITADEL oidc provider

Actual Result

Auth is rejected and I get the following log

[2026-01-02 17:49:28.122][vaultwarden::sso_client][DEBUG] Id token: XXX
[2026-01-02 17:49:28.122][vaultwarden::sso_client][DEBUG] Access token: XXX
[2026-01-02 17:49:28.122][vaultwarden::sso_client][DEBUG] Refresh token: None
[2026-01-02 17:49:28.122][vaultwarden::sso_client][ERROR] Could not read id_token claims, Invalid audiences: `some-other-id` is not a trusted audience

When decoding the Id token with

ID_TOKEN=XXX
echo "$ID_TOKEN" | awk -F. '{print $2}' | sed 's/-/_/g; s/ /+/g' | python3 -c "import sys,base64,json; s=sys.stdin.read().strip(); s += '=' * (-len(s) % 4); print(json.dumps(json.loads(base64.urlsafe_b64decode(s)), indent=2))"

I get:

{
// ...
  "aud": [
    "some-other-id", // the one reported in the error
    "again-some-other-id",
    "<client_id>", // the one  I gave in the SSO_CLIENT_ID
    "a-last-other-id"
  ]
// ...
}

Logs

Screenshots or Videos

No response

Additional Context

To me the issue is related to what's discussed in this ZITADEL Issue.
The fact is other services have troubles using ZITADEL as the oidc provider but this comment suggests ZITADEL is implementing the standard.
In addition, the errors mostly occurs with rust based services so I guess we have to look in this direction

In addition (slightly off topic) I don't get why we get an error if SSO_CLIENT_SECRET is missing or empty while using SSO_PKCE: true
