Les limites d’Active Directory – Mythes et réalités

On se pose souvent la question : Quelles sont les limites d’Active Directory : nombres d’objets, nombre de contrôleurs de domaine etc… ?

voici un excellent résumé du sujet http://technet.microsoft.com/fr-fr/library/cc756101(WS.10).aspx qui s'applique à: Windows Server 2000, Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 SP1, Windows Server 2003 SP2 et  Windows Server 2008

A retenir :

Maximum Number of Objects

Each domain controller in an Active Directory forest can create a little bit less than 2.15 billion objects during its lifetime.

Maximum Number of Security Identifiers

There is a limit of approximately 1 billion security identifiers (SIDs) over the life of a domain. This limit is due to the size of the global relative identifier (RID) pool of 30 bits that makes each SID (that is assigned to user, group, and computer accounts) in a domain unique. The actual limit is 230 or 1,073,741,823 RIDs.
