I am trying to get this setup and everything works fine with a local username and password but not when I try link it to Active Directory. Just gives me OpenVPN: Active Directory pre-authentication failed (K1:N255)
Is there a guide or something I can use for the setup.
Also how do I setup the VPN to use DNS records for our public static IP’s? Just in case we change them in future I do not want to be setting up a 100 VPN endpoints.
Hi @Gavin_Pitt,
That error can be thrown at least for two reasons:
- DHCP server is not configured on the balance router.
- The workgroup does not match the domain name which is sent to the server for authentication.
If those are well, please, submit a ticket so we can check further.

Ok I created a VLAN and setup DHCP and still get the error. What should I be using for Server Hostname, domain and workgroup? Would any user in AD have access?
Ok I have created a ticket.
We will follow up in the ticket.
