Get-ADOrganizationalUnit - Cmdlet Syntax and Examples



Gets one or more Active Directory organizational units.




The Get-ADOrganizational unit cmdlet gets an organizational unit object or performs a search to retrieve multiple organizational units.

The Identity parameter specifies the Active Directory organizational unit to retrieve. You can identify an organizational unit by its distinguished name (DN) or GUID. You can also set the parameter to an organizational unit object variable, such as $ or pass an organizational unit object through the pipeline to the Identity parameter.

To search for and retrieve more than one organizational unit, use the Filter or LDAPFilter parameters. The Filter parameter uses the PowerShell Expression Language to write query strings for Active Directory. PowerShell Expression Language syntax provides rich type conversion support for value types received by the Filter parameter. For more information about the Filter parameter syntax, see about_ActiveDirectory_Filter. If you have existing LDAP query strings, you can use the LDAPFilter parameter.

This cmdlet retrieves a default set of organizational unit object properties. To retrieve additional properties use the Properties parameter. For more information about the how to determine the properties for computer objects, see the Properties parameter description.
