ldapsearch over ssl/tls不起作用

Question

我试图在ssl/tls连接上使用ldapsearch,但它不起作用:

ldapsearch -ZZ -d 5 -b "cn=Users,dc=my,dc=server,dc=com" -s sub -D
"cn=mydevice,cn=Users,dc=my,dc=server,dc=com" -h my.server.com -p 3269
-w "mypass" -x "(cn=test)"

错误消息未提供有关错误的提示.相比之下,简单的绑定和搜索在端口389上没有任何问题.

任何提示？

PS这是我的ldap.conf:

TLS_REQCERT demand
TLS_CACERT ./cacert.pem

我甚至试图改变TLS_REQCERT到never,但它仍然无法正常工作.:-(

首先,替代-h my.server.com -p 3269与-H ldaps://my.server.com:3269被@dearlbry的建议.

然后,在/etc/openldap/ldap.conf(或/etc/ldap/ldap.conf在我的Ubuntu 13.04上),通过添加以下内容禁用证书验证:

HOST my.server.com
PORT 3269
TLS_REQCERT ALLOW

ldaprc如果您不想影响整个系统,也可以在当前目录中创建具有相同内容的文件.

这将启用SSL上的ldapsearch,但不进行验证.按照以下步骤将证书验证添加到组合中.
