RETURN VALUEsasl_checkpass returns an integer which corresponds to one of the following codes. SASL_OK indicates that the authentication is complete. All other return codes indicate errors and should either be handled or the authentication session should be quit. See sasl_errors(3) for meanings of return codes.
