You cannot filter system groups, such as Domain Users, when using the GetUsersByGroup SmartObject of the Active Directory AD Service 2 service.


The methods of the AD Service 2 SmartObjects translate to a single Lightweight Directory Access Protocol (LDAP) query by design. System groups are stored differently in Active Directory and require multiple LDAP sub-queries.


Depending on your scenario, you can use the GetUsers SmartObject and set Domain Users (or another system group) as an input parameter, and then filter by other criteria.
