Abstract: The present disclosure discloses a method and network device for using mobile devices with validated user network identity as physical identity proof. Responsive to successfully authenticating a client device for network access, a system generates a network credential for the client device and transmits the network credential to the client device. Further, the system detects that the client device is within a range of a short range wireless device that is associated with a particular physical action. Consequently, the system validates the network credential that the client device possesses. Based on the network credential, the system determines that the client device has permissions for performing the particular physical action, and causes performance of the particular physical action.

Abstract: In general, in one aspect, embodiments relate to receiving, by a system of one or more network devices from a client device, a request to access one or more applications, determining, by the system, that the client device has already been authenticated to access a network, and based on determining that the client device has already been authenticated to access the network, causing authenticating of the client device for accessing the one or more applications.

Abstract: The present disclosure discloses a method and a network device for controlling DHCP pool exhaustion in dynamic network environments. Specifically, a network device determines that a client device is assigned an Internet Protocol (IP) address by a DHCP server. The network device detects that the client device is disconnected from a network associated with the IP address, for example, by receiving a de-association message from the client device; determining that a session or an entry corresponding to the client device has timed out; determining that the client device has failed to respond to one or more messages transmitted to the client device; determining that the client device has connected to another network different than said network; etc. In response, the network device then generates a DHCP release message on behalf of the client device, and transmits the DHCP release message to the DHCP server.

Abstract: In general, in one aspect, embodiments relate to receiving, by a system comprising one or more network devices, a first client authentication information comprising a first indication that a first client device was successfully authenticated by a first authentication server based on credentials provided by the first client device, and forwarding, by the system, the first client authentication information to a second authentication server without determining that the client device was already successfully authenticated by the first authentication server based on the credentials provided by the first client device. The operations further include receiving, by the system from the second authentication server, a second indication that the first client device was successfully authenticated, and based on the second indication received by the system from the second authentication server, granting, by the system, network access to the first client device.
