I am writing an SMTP authentication plugin for qpsmtpd which will call vchkpw.Different error codes require different treatment; e.g. "incorrect password" is fatal, whereas some errors should probably allow a retry before dropping the connection.So can the various error code values from vchkpw be relied upon, or are they subject to change? Are they officially published somewhere in the doco/specs or is the source code the only authoritative reference?
They have to adhere to the standard set by the checkpassword implementation from DJB. http://cr.yp.to/checkpwd/interface.html is the interface, it's exit codes and how to react upon those exit codes.
Good luck, Bert JW Regeer
