DHCP Option for The Open Group's User Authentication Protocol
Alternative Format: Original Text Document
RFC 2485 DCHP Option for the Open Group's UAP January 1999 Most UAP clients have no local state and are configured when booted through DHCP. No existing DHCP option [6] has a data field that contains a URL. Option 72 contains a list of IP addresses for WWW servers, but it is not adequate since a port and/or path can not be specified. Hence there is a need for an option that contains a list of URLs. User Authentication Protocol Option This option specifies a list of URLs, each pointing to a user authentication service that is capable of processing authentication requests encapsulated in the User Authentication Protocol (UAP). UAP servers can accept either HTTP 1.1 or SSLv3 connections. If the list includes a URL that does not contain a port component, the normal default port is assumed (i.e., port 80 for http and port 443 for https). If the list includes a URL that does not contain a path component, the path /uap is assumed. 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Code | Length | URL list +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Code 98 Length The length of the data field (i.e., URL list) in bytes.
