我正在从一台服务器的紧急服务器传输中，我没有设置到一个新的硬件。 我正在用Postfix和Cyrus运行最新的Debian。 我已经从conf文件复制了大部分的细节，但是我仍然无法让服务器正常使用我的LDAP服务器。 我能够发送邮件与Postfix，但我不能检查任何东西似乎没有工作login。 我的validation日志显示：
May 28 14:48:55 server saslauthd[1101]: Authentication failed for user: Bind to ldap server failed (invalid user/password or insufficient access) (-7) May 28 14:48:55 server saslauthd[1101]: do_auth : auth failure: [user=user] [service=imap] [realm=] [mech=ldap] [reason=Unknown] 我很难过！

在saslauthd.conf中尝试更新如下（使用匿名绑定）：
ldap_servers: ldap://ldap.server.host.com:389 ldap_search_base: ou=People,dc=server,dc=host,dc=com ldap_filter: (uid=%u)
CentOS 7还有这两个configuration文件：
cat /etc/saslauthd.conf
ldap_servers: ldap://5.135.218.160:389 ldap_search_base: ou=People,dc=pb,dc=com ldap_filter: (&(uid=%u)(zarafaAccount=1))
cat /etc/sasl2/smtpd.conf
pwcheck_method: saslauthd mech_list: plain login
Debian的位置可能有所不同。 用testingconfiguration
testsaslauthd -u user1 -p mypassword -s smtp
不知道下面的错误消息意味着什么，但我应该是[服务= smtp]：
5月28日14:48:55服务器saslauthd [1101]：do_auth：auth失败：[user = user] [service = imap] [realm =] [mech = ldap] [reason =未知]
