OpenVPN server on Windows server, authorization login\password?

Question

openvpn

Good afternoon!
I must say right away that we are talking about authorization on the server side of OpenVPN, which is installed on Windows Server 2016.

What we have:
Windows server 2016 and an OpenVPN server configured on it with authorization by certificates.
Everything is working!

But it was necessary to additionally configure authorization by login and password.
I tried various methods:
1. openvpn-auth-script in Python
2. auth.vbs script

In both cases,
openvpn_execve appears in the server logs during authorization: CreateProcess C:\Program Files\OpenVPN\config\auth.py failed: Unknown error (errno =193)
WARNING: Failed running command (--auth-user-pass-verify): external program did not execute -- returned error code -1
TLS Auth Error: Auth Username/Password verification failed for peer

Both VBS script and Python script . Python in windows environment successfully launches py scripts from cmd with

python name_script.py key

Answer 1

Why a script? There is one line in the server config, about password authorization.
Details are on the ovpn website ...
Look at the list of parameters there
