Problem
You want to create a security or distribution group.
Solution
To create a security or distribution group, use the [adsi] type shortcut to bind to a container in Active Directory, and then call the Create() method:
$salesWest =
[adsi] "LDAP://localhost:389/ou=West,ou=Sales,dc=Fabrikam,dc=COM" $management = $salesWest.Create("Group", "CN=Management") $management.SetInfo()
Discussion
The solution creates a group named Management in the Sales West OU.
When you run this script against a real Active Directory deployment (as opposed to an ADAM instance), be sure to update the sAMAccountName property, or you’ll get an autogenerated default.
When you create a group in Active Directory, it is customary to also set the type of group by defining the groupType attribute on that group. To specify a group type, use the –bor operator to combine group flags and use the resulting value as the groupType property. Example 233 defines the group as a global, securityenabled group.
Example 233. Creating an Active Directory security group with a custom groupType
$ADS_GROUP_TYPE_GLOBAL_GROUP = 0x00000002 $ADS_GROUP_TYPE_DOMAIN_LOCAL_GROUP = 0x00000004 $ADS_GROUP_TYPE_LOCAL_GROUP = 0x00000004 $ADS_GROUP_TYPE_UNIVERSAL_GROUP = 0x00000008 $ADS_GROUP_TYPE_SECURITY_ENABLED = 0x80000000
$salesWest = [adsi] "LDAP://localhost:389/ou=West,ou=Sales,dc=Fabrikam,dc=COM"
$groupType = $ADS_GROUP_TYPE_SECURITY_ENABLED bor $ADS_GROUP_TYPE_GLOBAL_GROUP
$management = $salesWest.Create("Group", "CN=Management") $management.Put("groupType", $groupType) $management.SetInfo()
If you need to create groups in bulk from the data in a CSV, the ImportADUser script. To make the script create groups instead of users, change this line:
$newUser = $userContainer.Create("User", "CN=$username")
to this:
$newUser = $userContainer.Create("Group", "CN=$username")
If you change the script to create groups in bulk, it is helpful to also change the variable names ($user, $users, $username, and $newUser) to correspond to grouprelated names: $group, $groups, $groupname, and $newgroup.
