我正在升级各种Debian 6服务器到Debian 7.有一些小问题，但这是一个展示塞尔。

在Debian上，Postfix运行在chroot环境中。 该环境设置正确（它在Debian6上工作正常）。

我只使用debian版本库的稳定版本中的软件

相关的（部分）configuration（匿名）：

• mysqldump无法导出特定的数据库，phpMyAdmin崩溃
• / var / run / saslauthd在重新启动时更改权限
• 如何在启动时select新内核，运行专用服务器？
• 如何防止包从其他回购更新？
• 固定TCP有效载荷大小

在/ etc / default / saslauthd中：

START=yes DESC="SASL Authentication Daemon" NAME="saslauthd" MECHANISMS="ldap" MECH_OPTIONS="" THREADS=5 PARAMS=" -m /var/spool/postfix/run/saslauthd -O /etc/saslauthd.conf" OPTIONS=" -m /var/spool/postfix/run/saslauthd -O /etc/saslauthd.conf" PIDFILE="/var/spool/postfix/run/saslauthd/saslauthd.pid" 

在/etc/saslauthd.conf中：

 # With multiple servers, separate URIs with a space ldap_servers: ldaps://my.ldap.server # Don't use SASL to connect to LDAP!! (Use SSL) #ldap_version: 3 ldap_use_sasl: no ldap_bind_dn: uid=courier,ou=roles,dc=mydomain,dc=tld #watch out for trailing whitespace after the pasword! ldap_bind_pw: ####### ldap_timeout: 10 ldap_time_limit: 10 ldap_scope: sub ldap_search_base: ou=people,dc=mydomain,dc=tld ldap_auth_method: bind ldap_filter: (mail=%u) #ldap_filter: (mail=%u@%r) ldap_debug: 1 ldap_verbose: off ldap_referrals: yes # Settings below are needed for ldaps URIs ldap_ssl: yes ldap_start_tls: no ldap_tls_cacert_file: /etc/ssl/certs/allcacerts.pem ldap_tls_cert: /etc/ssl/certs/myserver.mydomain.tld.crt ldap_tls_key: /etc/ssl/private/myserver.mydomain.tld.key 

在/etc/postfix/sasl/smtpd.conf中：

 #global parameters log_level: 5 # WARNING !!! POSTFIX runs in a chrooted jail!! # Need to adjust paths to get the socket available! # adjust this in /etc/defaults/saslauthd # eg: PARAMS=/var/spool/postfix/run/saslauthd/ # real saslauthd_path: /var/spool/postfix/run/saslauthd/mux pwcheck_method: saslauthd saslauthd_path: /run/saslauthd/mux mech_list: PLAIN LOGIN auxprop_plugin: ldapdb #allow_plaintext: true #the database used is /var/spool/postfix/etc/sasldb2 

在/etc/postfix/main.cf中

 #sasl configuration smtpd_sasl_auth_enable = yes smtpd_sasl_path= smtpd smtpd_sasl_security_options = noanonymous smtpd_sasl_local_domain = #broken_sasl_auth_clients = yes # TLS configuration smtpd_use_tls = yes smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_key_file = /etc/ssl/private/myserver.mydomain.tld.key #smtpd_tls_cert_file = /etc/ssl/certs/myserver.mydomain.tld.crt smtpd_tls_cert_file = /etc/ssl/certs/myserver.mydomain.tld.pem tls_random_source = dev:/dev/urandom # CAfile is read BEFORE entering chroot jail smtpd_tls_CAfile = /etc/ssl/certs/allcacerts.pem # CApath is used withIN chroot jail #smtpd_tls_CApath = /usr/share/ssl/certs/ 

赛勒斯SASL在/var/spool/postfix/run/saslauthd/mux有套接字

我testing：

testsaslauthd -s smtpd -f /var/spool/postfix/run/saslauthd/mux -u [email protected] -p PASSWD

给出： 0: OK "Success."

仅供参考：凭证不正确确实失败:)

有了这些结果，我的结论是sasl工作正常。

当我使用'swaks'来testingESMTP身份validation：

swaks -s myserver.mydomain.tld -p 25 -ehlo myclient.mydomain.tld -au [email protected] -ap PASSWD -t [email protected] -f [email protected]

 === Trying myserver.mydomain.tld:25... === Connected to myserver.mydomain.tld. <- 220 *********************** -> EHLO myclient.mydomain.tld <- 250-myserver.mydomain.tld <- 250-PIPELINING <- 250-SIZE 15360000 <- 250-VRFY <- 250-ETRN <- 250-XXXXXXXA <- 250-AUTH PLAIN LOGIN <- 250-ENHANCEDSTATUSCODES <- 250-8BITMIME <- 250 DSN -> AUTH LOGIN <- 334 VXNlcmgfhgWU6 -> bWFyY2hgh28ubmw= <- 334 UGFzfghdfmQ6 -> bWFyUzYdfghgfhg== <** 535 5.7.8 Error: authentication failed: no mechanism available -> AUTH PLAIN AG1hcmdfhgdfgd1hclM2NW9ndCo= <** 535 5.7.8 Error: authentication failed: no mechanism available *** No authentication type succeeded -> QUIT <- 221 2.0.0 Bye === Connection closed with remote host. 

而在日志中：

（IP是客户机）

后缀用户是sasl组的成员。

我知道Debian通过插入一个三元组来改变库的目录结构，使其具有多重能力。

以前是/usr/lib/sasl2 ： /usr/lib/x86_64-linux-gnu/sasl2 （用于x86 64位系统）

我没有将sasl2目录复制到各个地方，以使这些库可用，但它并没有改变。

任何人？
