ssl - OpenLDAP - TDS - 无法联系 LDAP 服务器 (-1)

Question

我想尝试通过 ldapsearch 连接到 TDS - 服务器。首先，我下载了“OpenLDAP”，但现在使用以下命令:

ldapsearch -H ldaps://myhostadress:636

我总是收到以下错误:

ldap_sasl_interactive_bind_s: Can't contact LDAP serv
additional info: error:14090086:SSL routines:
:certificate verify failed (self signed certificate)

我附加到我的命令“-d1”以获取更多信息并得到:

ldap_url_parse_ext(ldaps://xxx:636)
ldap_create
ldap_url_parse_ext(ldaps://xxxx:636/??base)

我认为这与 ssl 证书有关!？我已经阅读了一些其他有类似问题的线程。
之后，我向我的管理员询问了 ssl 证书并获得了一个具有以下结构的 .pem 文件(它只是一个摘录):

-----BEGIN CERTIFICATE----
mcdp+Kh5Zd3YOttXbjemxIvwfRvPd/Ho4VtBsi5yJT5DSehL4L8ZN
DKaSL6BQ5MlQ1bsmQQ04PKNBrPKFFIiadi9QsFrUiNCQSKDLSKDSK

hL4L8ZNL6BQ5MlQ1bsmQQ04PKNBrPKFFIiadi9QsFrUiNCJKLSADN
.....................................................
.....................................................
-----END CERTIFICATE-----

我现在该怎么办？证书的 OpenLDAP 文件夹是

`C:\OpenLDAP-2.4.43\etc\certs

和中的配置文件，

`C:\OpenLDAP-2.4.43\etc\openldap`

我已经按照 Performing ldapsearch over TLS/SSL against Active Directory 中的说明进行了尝试并添加到我的 ldap.conf

HOST hostxyz.com
PORT 636
TLS_CACERT \etc\certs\trustKey.cer     //  C:\OpenLDAP-2.4.43\etc\cert\trustKey.cer   ; .pem file changed into .cer file
TLS_REQCERT demand

并以 ldapmodify -H ldaps://hostxyz.com:636 开始通话
但我总是收到提到的错误。

此致

这对我有用!
将此添加到文件/etc/openldap/ldap.conf

TLS_REQCERT allow

然后重新启动 LDAP

systemctl restart slapd
systemctl enable slapd
