    All,

    The two causes of Digest failure of which I am currently aware are:
       1) The IPP Client did not properly handle a Printer's "100 continue" HTTP
    message
       2) The nonce used by a Client contained a possible illegal character of a
    space character (i.e. ' ' or 0x20). The Printer was using a space as its
    delimiter in parsing.

    I'll let you know if I receive other causes of failure.
    Pete

    Mike,

    As noted in the document one of the major problems was the "100 continue"
    that some Clients handled incorrectly. The biggest problems we saw were in
    the Digest authentication test. We would have to ask the actual
    implementers to let us know about the causes of the failures other than the
    "100 continue".

    Implementers may send the causes of authentication failures to me and I will
    update the Bake-Off Summary document and send the issues out to the IPP list
    maintaining the privacy of the Bake-Off participants.

    Do we know what were the causes of the authentication failures?

    Pete

    Going through the results document for bake-off #3, it mentions
    some authentication issues with HTTP, but doesn't go into any
    details.

    Will a follow-up (detail) document be provided to the list, or can
    we at least get the break-down of the authentication failures?
