A system, comprising: a first network domain seed configured to be coupled to (1) a first network domain member supporting a first virtual local area network (VLAN) and (2) a network database storing authorization information of a client, the first network domain seed being physically separate from the first network domain member; the first network domain seed configured to be coupled to a second network domain seed coupled to (1) a second network domain member supporting a second VLAN and (2) the network database, the second network domain seed being physically separate from the second network domain member; the first network domain seed configured to receive a query from the first network domain member, the query indicating that the client is attempting to connect to the second VLAN through the first network domain member; the first network domain seed configured (1) to perform a lookup in the network database based on the query to determine that the client is authorized on the second network domain member, and (2) authorize the client to connect to the second network domain member through the first network domain member via VLAN tunneling.
