Hi, I configured an OpenVPN Server on my OPNsense with this HowTo:

I had to create local users and create unique OpenVPN certificates for each user. That works for this user, but I guess this doesn't work with local domain users.
How should I approch this? Disable certificate Usage?
Edit:
I solved it with an "instance" server and no certificate usage (I use MFA and username / password)
