Problems with commas in the DIGEST-MD5 impletation

[Remko Tronçon]

Hi,

We just got the report that the following SASL challenge:
    , realm="localhost", nonce="LlBV2txnO8RbB5hgs3KgiQ==", qop="auth,
auth-int, ", , ,
    charset=utf-8, algorithm=md5-sess,
is not understood by Cyrus SASL. Apparently, the extra commas in the
middle are causing trouble, although the syntax is correct according
to RFC 2831. The challenge itself was generated by GnuSASL i believe.

cheers,
Remko
