Bypass authantification using windows credentials with ntlm

Nextcloud version: 13.0.5
Operating system and version: Ubutnu 18.04 LTS
Apache or nginx version: nginx (but apache2 is installed and configured, too - but deactivated)
PHP version: 7.2 (fpm)

The problem you are facing:

I’d like to implement authentification with ntlm.
The goal is that the user does not have to fill in his credentials.
Instead, the windows credentials are passed directly to the nextcloud.
Does anyone have experience with it or knows a tutorial?

Thanks in advance
