Good day. The question arose about the need to purchase the licensed version of Windows Server.
Plan to take the Essentials edition, which has a limit of 25 users.
Actually a question: one copy of Essentials is limited to 25 users, if we in the future want to expand the organization to, say, 50 users, will I be able to buy another copy of Essentials and re-enter it in the domain?
And the question is a little aside: does it make sense to raise a second domain controller on Linux? Whether there will be a limit of 25 users?
1. No, you cannot. From Essentials of restriction on the number of domain users (it accounts, not real users. When you try to create a new snap-in will pop up) . Besides, if essentials is a domain controller, it should be the only domain controller on the network and bilateral relations with other CD can not have. If the number of users will increase, your choice - switch to standard edition and above.
2. As a second controller in linux you can use if the forest level 2008r2 does not exceed, in the case of a domain on Samba. About FreeIPA can't say anything. My opinion - or so entirely on the Linux directory, and RADIUS to lift, or the entire AD. Full redundancy in a hybrid circuit to achieve, I believe, unrealistic. In the framework of the organization would not tolerate such perversions.

If I remember correctly - essential is the ceiling of one domain controller and 25 users and even without the ability to build trusts with other domains....
Here is what is the mechanism of this restriction - "you must in words" or "technically impossible" - do not tell. In the second case, will have fun with storage uchetok fired...
