Changes are made to a virtual network for an endpoint based on the authenticated user identity of the endpoint. The system includes a server and a controller associated with a network fabric to which the endpoint is connected. The network fabric includes network elements to carry network traffic for the endpoint. The server authenticates the endpoint associated with a network address and determines a user identity of the endpoint based on the authentication. The server determines a first virtual network associated with the user identity. The controller receives a notification from the server that the network traffic for the endpoint associated with the network address is to be routed over the first virtual network. The controller updates routing information to associate the network address with the first virtual network and sends the updated routing information to the network elements of the network fabric.
