Proxmox VE 8.2 + Dex OIDC – How to Force a Specific Connector (Skip Connector Selection)

Hi all,
I’m currently integrating Proxmox VE 8.2 with Dex (OIDC) as the identity provider, and overall the authentication flow is working correctly.
However, I’m trying to determine whether Proxmox supports forcing a specific Dex connector per realm.


connectors:
- type: microsoft
id: microsoft
name: My AD

- type: ldap
id: freeipa
name: FreeIPA


Authentication works for both connectors.​

Desired Behaviour

For Proxmox specifically, I would like to:
  • Skip the connector selection screen
  • Force authentication via the microsoft connector
  • Keep FreeIPA available for other applications

What I Have Tried​

  1. Attempting to add connector-id / openid-connect-connector-id to /etc/pve/domains.cfg
    → Proxmox 8.2 rejects it with:


unable to parse value of 'connector-id': unknown property type

Does Proxmox VE 8.2 support passing connector_id to Dex (or otherwise selecting a specific connector per realm)?
Any clarification or best-practice guidance would be appreciated.

Thanks
Yaser
