Active Directory Sync Error

[rhett.bates]

All,
I am trying to simply follow the tutorial to connect my Proxmox server to an Active Directory that is being run in one of my VMs. When I follow the steps to connect to the AD, when I attempt to Sync after adding the AD to the Realms, I get a "TASK ERROR: Protocol not available". I have searched quite a bit, and I haven't seen anyone else have this issue. I am sure I am making some rookie mistake, but if someone could point me in the right direction it would be greatly appreciated. Thanks!
FYI: This is Proxmox 7.1-7.

Hello,

could you share the realm configuration from /etc/pve/domains.cfg?

Thanks!

Whenever we attempt to Preview or Sync the AD after adding it to the realms, it immediately fails with the TASK ERROR: Protocol Not Available. It doesn't even attempt to try and reach the server, so I'm not sure what protocol it is referring to. If I knew the protocol that wasn't available, I could try some fixes, but I don't know what protocol it is attempting to use that it just doesn't have.

Hmmm, I've attempted to recreate the issue. My AD config pretty much looks exactly like yours, but for me it works:

ad: ad
    domain ad.example.com
    server1 192.168.19.xxx
    bind_dn CN=Administrator,CN=Users,DC=ad,DC=example,DC=com
    default 0
    secure 0

Do you have any other clients that already use the AD successfully? At this point I'd suspect some misconfiguration on the AD side.
