postfix 无法通过 saslauthd 进行身份验证

Question

肮脏的修复

来自 smtpd.c

/* smtpd_sasl_auth_cmd_wrapper - smtpd_sasl_auth_cmd 前端 */

静态 int smtpd_sasl_auth_cmd_wrapper（SMTPD_STATE *state，int argc，SMTPD_TOKEN *argv）

来自 smtpd_sasl_proto.c

/* smtpd_sasl_auth_cmd - 处理 AUTH 命令 */

int smtpd_sasl_auth_cmd（SMTPD_STATE *state，int argc，SMTPD_TOKEN *argv）

来自 smtpd_sasl_glue.c

/* smtpd_sasl_authenticate - 每个会话的身份验证 */

int smtpd_sasl_authenticate（SMTPD_STATE *state，const char *sasl_method，const char *init_response）{int status; const char *sasl_username;

.........

    /*
     * HERE WE ARE.
     * it seems that status is always != XSASL_AUTH_DONE for some unknown reason !!!!!!!
     * I am not too much into this code but the problem is here
     * Even though saslauthd answer OK status is not the right value so authentication fails.

     * for my golas I have commented the code so to skip check (very dirty hack)
     * and recompiled postfsix from scratch
     */

if (status != XSASL_AUTH_DONE) {
    msg_warn("%s: SASL %s authentication failed: %s",
             state->namaddr, sasl_method,
             STR(state->sasl_reply));
    /* RFC 4954 Section 6. */
    if (status == XSASL_AUTH_TEMP)
        smtpd_chat_reply(state, "454 4.7.0 Temporary authentication failure: %s",
                         STR(state->sasl_reply));
    else
        smtpd_chat_reply(state, "535 5.7.8 Error: authentication failed: %s",
                         STR(state->sasl_reply));
    return (-1);
}

..........

return (0);

}
