Access the Administration Server and choose the Global Settings tab.
Click Configure Directory Service.
From the Create New Service of Type drop-down list, choose the type of directory service you want to create.
You can now configure the directory service information in the page corresponding to the type of directory service you have selected.

Click Save Changes to save your changes.
Once you create and configure directory services, you can assign directory services per virtual server. The rights and permissions associated with the directory service is later used by the server to evaluate and enforce access control rules.
