Hi,
Recently encountered an issue after trying to set up a device license for a customer.
It seems that it isn't possible to assign this license to the security group (through Entra, M365 admin center) without an Entra P1 license.
But, group-based licensing also has the requirement of having as many licenses as assigned users:
For any groups assigned a license, you must also have a license for each unique member. While you don't have to assign each member of the group a license, you must have at least enough licenses to include all of the members. For example, if you have 1,000 unique members who are part of licensed groups in your tenant, you must have at least 1,000 licenses to meet the licensing agreement.
This is contrary to how device licenses 'should' work, I think:
You can add as many users to the Dynamics 365 Business Central Device Users group as you need. However, the number of devices that users can simultaneously sign in to is defined by the number of purchased device licenses.
Yet, when assigning more users than there are licenses to the group, the users that exceed the amount of licenses show an error on license page of that user that the 'inherited device license' exceeds the available amount. This might be purely visual, is in line with the requirements of group-based licensing.
The D365 license guide also doesn't mention the requirement of an Entra P1 license to use/assign device licenses.
It seems that Device licenses need to follow 2 different sets of 'requirements', both of the Device licenses itself and group-based licensing.
