Hello, I'm writing an SMTP-server application that maintain its own user/password database. How can I use Cyrus-SASL with my application for CRAM-MD5 (DIGEST-MD5 and so on) authentication ? For PLAIN & LOGIN mechanisms Cyrus-SASL has a callback sasl_server_userdb_checkpass_t which allows to check username & password agains the caller-supplied database. I think, another callback, which gets an username (and, possible, a realm) and return plain-text password back to the SASL engine, will be appropriate for my needs. An hour later: I found that SASL 1 had sasl_server_getsecret_t callback which did something like I need. Why was this callback removed in SASL 2 ? Does SASL 2 use another way for the caller-supplied database for CRAM-MD5 mechanism ? I would be very appreciative of examples or any hints. Thanks for help. -- Best regards, Denis Malyshkin, C++ Developer of ISS Art, Ltd., Omsk, Russia. http://issart.com http://issart.com/index/Portfolio/cpp&lang=eng mailto:dmalyshkin@xxxxxxxxx
