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
