In average AD forests, groups govern authorization to sensitive data. Groups can distribute content or help to give access to files, services or even AD delegation. After installation you will gain several built-in groups such as Domain Admins group or Account Operators.

The Active Directory Users and Computers (ADUC) and the Active Directory Administrative Center (ADAC) are programs that provide graphic UI to interact with groups and help to manage them. ADAC differs from ADUC in a way that it has PowerShell History this provides the ability to see the PowerShell cmdlets behind the GUI.

In order to manage groups, you have to sign in to a DC, a doman-joined server, or a device with the Remote Server Administration Tools (RSAT) installed.
Speaking about access level you need to have a domain admin account, the Account Operators account, or have rights to create groups in certain OU via delegation.

Group Scopes

There are three group scopes:

  • Global groups
  • Universal groups
  • Domain local groups

When deciding what group to create, you need to know what are the group types and how they differ. Global groups and universal groups can be nested into domain local groups and global groups can be nested into universal groups. Therefore, it is very popular that global groups are created for departments, universal groups for distribution groups, and domain local groups for access rights.

Group Types

There are two group types:

  • Distribution groups
  • Security groups

Distribution groups do not have a security identifier (SID) and, therefore, can't be used to allow access to resources, except for resources within Microsoft Exchange Server. On the opposite side security groups do have SIDs. It is possible to convert a distribution group into a security group, and vice versa.
