Claim 16:
17. An authentication server comprising:
a processor; and
a non-transitory computer-readable media storing instructions that, when executed by the processor, causes the processor to perform operations comprising:
receiving, from a client device, a request for a first dynamic host configuration protocol (DHCP) option;
determining if the authentication server implements DHCP;
based at least in part on the authentication server does not implement a DHCP protocol:
transmitting an application program interface (API) call to a DHCP server associated with the authentication server acting as a DHCP gateway, a representational state transfer (REST) wrapper being applied to the API call such that the first DHCP option is secured; and
receiving a response from the DHCP server; and based at least in part on the authentication server does implement DHCP protocol, transmitting to the client device a response from the authentication server; transmitting the response received from the DHCP server to the client device, wherein the response received from the DHCP server comprises: the first DHCP option; and a second DHCP option separated from the first DHCP option, the second DHCP option being a non-requested option with respect to the first DHCP option and comprising a pointer to the authentication server.
