Active Directory Data Store configuration of LDAP User & Groups Container Value - can be blank

Docs for the Active Directory DataStore configuration , should explain that the LDAP People and Group Container value field can be blank. If you put a value in the field, it will force AM to look in that specific container for users and/or groups. But if you leave the LDAP People Container Value and LDAP Group Container Value blank, it will list ALL users and groups in AD.

Current docs show this:

LDAP People Container Value
RDN attribute value of the LDAP base DN which contains user profiles.

ssoadm attribute: sun-idrepo-ldapv3-config-people-container-value

Default: users

and

LDAP Groups Container Value
RDN attribute value of the LDAP base DN which contains group profiles.

ssoadm attribute: sun-idrepo-ldapv3-config-group-container-value

Default: users

These do not explain what happens if there is no value, or that it can even be blank.
