On the domain controller, open the application named Windows Firewall with Advanced Security

Create a new Inbound firewall rule.

Congratulations, you have created the required firewall rule.

This rule will allow the OTRS server to query the Active Directory database.

Tutorial Windows - Domain Account Creation

Next, we need to create at least 2 accounts on the Active Directory database.

The USER01 account will be used to login on OTRS as an agent.

The BIND account will be used to query the Active Directory database.

On the domain controller, open the application named: Active Directory Users and Computers

Create a new account inside the Users container.

Zabbix active directory account

Create a new account named: USER01
