Abstract: Examples relate to configuring dynamic user roles that can be managed and distributed by a cloud-based user role service. In this way, dynamic user roles may be distributed in a more scalable manner than has been previously possible. Upon associating or connecting to an access point (AP), for example, a user device can be authenticated and assigned a user role. The AP can request the user role configuration from the cloud-based user role service. The cloud-based user role service can additionally distribute the same user role configuration/details to all neighboring APs. In this way, a user device can move, roam, or otherwise associate to another AP that post-distribution, already has the (dynamic) user role configuration, which can simply be applied to the user device.
