FortiAuthenticator

[kitsune242]

Hi,

I've encountered an issue with FortiAuthenticator while trying to configure it as an OpenID authentication provider. However, Proxmox is not accepting this configuration properly and keeps throwing the following error:


I don't really have an idea where to look for the root cause of this issue. I've already tried several approaches, but none seem to work.
Fortiauth config



and proxmox




Client KEy and ID delete for screen

Do you have any suggestions on how to troubleshoot or resolve this problem?

I don't know the answer, but have you also looked in the DEBUG? Duplicate the browser tab for your FortiAuthenticator, and append /debug to the URL. This will show more debugging data.

I checked the logs, and there was nothing related to any connection attempts—it looks like Proxmox isn't even trying to reach FortiAuthenticator. I verified the network configuration, and everything is accessible without any issues. When I test it from the CLI, it works fine, and I receive all the expected responses. However, it doesn’t work from the user GUI. Previously, I had it set up with Keycloak, and it worked correctly.



This config (client secret changed) evrything is good when using oauth2 so FortiAuth works fine ... problem is in Proxmox
