Abstract
A method and apparatus is provided to control the admission of a user to a network by preventing a port through which the user connects to the network from forwarding data packets until the user is authorized. A network login controller operates in conjunction with a user interface to receive a user identification data from the port user. The network login controller further operates in conjunction with an authorization server to authenticate the user by sending a user authentication request containing the user identification data to the authentication server. The network login controller grants or denies permission to the user to access the network based on the user authentication response from the authentication server. If permission is granted, then the network login controller unblocks the port through which the user is connected to place it in packet-forwarding mode. If permission is denied, then the port remains in packet non-forwarding mode (i.e. it remains blocked).
