KB-0048: Can a user and group have the same name in AD?
Can a user and group have the same name in AD?
his is possible in other OS platforms but not in Windows OS. In Active Directory it is not possible to have same login name for both the user and group because it treats each of these as separate objects so they need to have unique 'samaccountnames'.
It is possible to have the same display name if they are under different containers.
