Enable Active Directory Lightweight Directory Services
In the "Programs and Features" control panel, click the "Turn Windows features on or off" and enable the AD LDS feature:
Launch the wizard
It is located in the app menu, under Windows Administrative Tools:
In the wizard, I chose to create a single instance, named TestAD1, with the default LDAP ports 389 and 636 (for SSL connection).
Then I chose to create an Active Directory Partition and named it "CN=MyTestPartition1,DC=local,DC=example,DC=com":

Browse the AD with ADSI Edit
Launch ADSI Edit and choose Action / Connect to...
Add nodes with ADSI Edit
Right click on a node and choose New / Object:
Connecting Apache Directory Studio to this AD instance
Make sure to select the JNDI provider:
