Connect to an internal Azure LDAP server from Nextcloud

Nextcloud version : Nextcloud Hub II (23.0.0) @ netways.de
Operating system and version : SaaS Nextcloud Hub II (23.0.0)
Apache or nginx version : default
PHP version : default

The issue you are facing: I am not able to connect to an internal IP of our LDAP Azure AD server.

Is this the first time you’ve seen this error? Y

Steps to replicate it:

  1. Install app LDAP user and group backend reference
  2. Try to connect to Azure
  3. Does not works as it’s not the same environment and the Azure AD has only an internal IP

The output of your Nextcloud log in Admin > Logging:
not needed as there is not even the chance to connect to an internal IP without special configurations

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

default

The output of your Apache/nginx/system log in /var/log/____:

default

Is this even possible. If so how to connect to the LDAP server from Nextcloud?
