Setting Global Password Policies

I'm setting up a new macOS Sierra with Server 5.2.

According to Server 5.2 Help:

Password policies don’t affect administrator accounts. Administrators are exempt from password policies, because they can change these policies, and because enforcing password policies on administrators could subject them to denial-of-service attacks.

1. Select Open Directory in the Server app sidebar.
2. Click Servers.
3. Click and choose Edit Global Password Policy.You can set global policies for user logins and passwords. To define your global policy, select a restriction or requirement, then enter a value as needed.
4. Click OK.

but I don't see "Edit Global Password Policy" when I click the config popup. Only "Archive Open Directory Master..." and "Promote Replica To Master..." (greyed out). Any hints?
