Question

我为我的服务器创建了自签名证书，未加密端口下的StartTLS也没问题，但我也需要在加密端口下运行，因为Jenkins ldap-plugin无法使用StartTLS功能。

我用：

启动我的服务器

slapd -h "ldap:/// ldaps:///" -f /etc/ldap/slapd.conf -d config -d conns -d packets

如果我运行这个ldapsearch：

ldapsearch -d 1 -v -H "ldaps://[server ip]" -D "[manager dn]" -w [manager password]

我收到此错误：

ldap_url_parse_ext(ldaps://172.17.0.1)
ldap_initialize( ldaps://172.17.0.1:636/??base )
ldap_create
ldap_url_parse_ext(ldaps://172.17.0.1:636/??base)

ldap_close_socket: 4
ldap_err2string
ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)

但如果我运行openssl来测试连接：

openssl s_client -connect [server ip]:686

我收到它没关系：

CONNECTED(00000003)

有人能发现我的错误吗？还是指点一个方向？

谢谢！

Answer 1

我终于解决了这个问题。

我在端口686启动了安全slapd，而默认安全端口是636，所以当客户端尝试连接到安全端口时，端口是错误的。我将安全端口设置为636，这是默认设置。

其他错误，服务器证书必须在CN字段使用完全限定的域名，我使用example.com作为测试，但它必须是服务器地址。由于我没有服务器的域名，因此我使用了服务器IP。

在SLAPD中允许LDAPS服务
