  • Hi

     AFAIK there is no problems with the used editions (Standard or Enterprise) on Active directory.Also you can check this article for "Active Directory Maximum Limits - Scalability"

  • Thank you for answering. Terminal Services can go up to 10 users with concurrent connections before they make you pay. So, I thought they do to Active Directory as well.

  • Per the article Burak linked, the only limit is for the number of SID's that can be assigned in a domain. SID values are required for all security principals. So the limit is to the total number of users, computers, and groups. This includes all such objects ever created, even if some where later deleted. The limit was 2^30 -1, until Windows Server 2012 when the limit was increased to 2^31 -1.
