When the printer attempts to connect to the
URL in the HTTP POST alert, the server may require HTTP authentication
(such as digest, basic, DNS, etc.). There may be multiple authentication
requests along the route to the destination (for example, a local
server first requires HTTP authentication as well as on the remote
server). For each HTTP authentication request received while attempting
to connect, the printer will enumerate the authentication entries
and attempt to satisfy the request with the username/password pair
provided for the respective server. The server name in the entry
is what determines which username/password pair should be used for
which authentication request. Both DNS names and IP addresses are
acceptable.
The server, username, and password are separated
by a single space (not a tab or other white space character). The
server name is the only required field. If no username is supplied,
but a password is, there must be two spaces between the server and
the password fields. If there is a username but no password, or
simply just the servername, no space is required at the end of the
entry.
