we have not yet worked out all the details, but a binary value will
certainly not cut it.
I foresee the need for a multi-valued attribute that lists the supported
security protocols (if any) for a particular Printer and we will probably
need to allocate some of these values, unless some other group in the IETF
has already done that work for us.
Secondly, certain security protocols, such as TLS, actually requires that
the session between the client and the server is initiated over the
security protocol, rather than over IPP/HTTP, which means that you need a
separate URL for that Printer which starts off: https://www......
For such cases, we need to decide whether we need to make two separate
directory entries considering that the Printer may now have a "secure URL"
and a "normal URL" if it supports both types, or if the "secure URL" is
just an extra directory attribute in the entry for the "normal URL"
version. However, some printers may only accept secure communication, in
which case there is no valid "normal URL".
Confused enough? We will need to do some more work on this in the SEC
Suggestions from the DIR subgroup or anybody else are obviously welcome.
