Waiting Dynamics NAV as full SaaS solution (Dynamics 365 ‘Tenerife’), a lot of partners are deploying NAV on Azure with subscription licenses. Subscription license has much better price in comparison with perpetual model, even from only BREP.
But we have a small difference here. In perpetual licensing model, users are concurrent, but n subscription model, users are named. Because of that I’ve got a lot questions how system count these users and prevent bigger number of users from licensed.
Generally, this is very easy. NAV counts number of created users and compare it with your subscription license. That moment, when you try to create new user, more than you have licensed, system will stop you.
As you can see on the previous picture, I’ve got a message that creating this new user will not meet the terms of the current license. OK, it works. That means if you want to change user, you need to delete old one and than create new one.
But in subscription model, you can change number of users monthly. What if you had in one moment, because of business needs, more licensed users and now you scaled down number of users? In this case, when you try to log in, system will show the following message:
That means with current license and number of users, you are not legal. But if you press OK, system will allow you to log in. But every time when you try run NAV, you will get this violation message that shows you are not legal.
