I work in a company and I have been confronted with the following problem.

I have to mount a server with windows 2012 Server R2 in which Active Directory will be installed to control the logins of about 25 users. A part will also install a management program that about 10 people will use connecting from their computers with a client program.

The question I have is whether with the standard version I could do this or I would need to buy CALs for the 25 users that will use the Active Directory.

Yes you will need CALs per user / device if you use Windows Server 2012 R2 Standard as soon as your user / device connects to your server.

However, Windows Server 2012 R2 Essentials includes 25 User CALs using up to 50 devices, so maybe this could be an option.

Some more info from a blogpost on Technet and this related serverfault question.
