vsftpd + pam_ldap + openldap 验证不成功, 本地帐号登陆成功。
请问哪里可以看openldap的登陆日志，怎么看我的pam_ldap 已经连接到openldap了？
各位请帮忙看看，谢谢！

我手工导入了一个 dn：

ldapadd -x -D 'cn=root,dc=it,dc=com' -W
dn: uid=cc,dc=it,dc=com
objectClass: person
objectClass: organizationalPerson
objectClass: inetOrgPerson
uid: cc
cn: cc
sn: cc
userPassword:: 123456
telephoneNumber: 138888888

telexNumber: tex-888888
street: my street
postOfficeBox: postofficebox
displayName: qqdisplay
homePhone: home1111111
mobile: mobile99999

登陆测试验证，是否可以用用户名：cc 密码：123456？
好象导入到openldap后userPassword加密了，不知是否密码 明文和密文的关系？

以下是我查询的结果

“openldap的安装笔记，请大家多点关注ldap技术。”这个帖子里说了：

关于log的设置：
增加了日志功能，需修改syslog配置文件，在文件中增加一项：
local4.*         /var/log/ldap.log
日志级别定义可查相官方网站的文档。1级记录的信息很多。可用于调试。

需要修改/etc/syslog.conf

我也是同样的问题；

找不到用户，不知道为什么？
