What is difference between OU and group? OUs contain user objects, groups have a list of user objects. You put a user in a group to control that user’s access to resources.
The main difference between “Organizational Units (OUs) and groups in Active Directory” is that OUs contain user objects and help in organizing them within the directory, allowing for the application of policies and delegation of administrative tasks, while groups contain a list of user objects and are used to assign permissions and rights to multiple users at once.
Can a user be in multiple OU? A user can be moved from one OU to another, but at any one point in time, it only resides in ONE location. So, NO, a user cannot be a member of two OUs in Active Directory.
Why do we need OU in Active Directory? Organizational units (OUs) in an Active Directory Domain Services (AD DS) managed domain let you logically group objects such as user accounts, service accounts, or computer accounts. You can then assign administrators to specific OUs, and apply group policy to enforce targeted configuration settings.
What is GPO and OU? Group Policy objects applied at the site level to a particular Active Directory site. Domain GPOs. Group Policy objects applied at the domain level to a particular Active Directory domain. Organizational Unit (OU) GPOs. Group Policy objects applied at the OU level to a particular Active Directory OU.
