apache - org.apache.karaf.jaas.modules.ldap 无法为 LDAP 设置 SSL 支持

Question

我目前正在运行一个 OpenLDAP 2.4.45 实例作为我的 Talend ESB 容器的验证器。我正在使用 TLS 连接到 LDAP，我已经设法让我的 JMS 代理连接并使用 org.apache.activemq.jaas.LDAPLoginModule 成功地使用了 LDAP，但是，在使用 org.apache.karaf.jaas 时.modules.ldap.LDAPLoginModule 用于 Web 服务，我得到以下堆栈跟踪:

我的验证器配置文件:

<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
  xmlns:jaas="http://karaf.apache.org/xmlns/jaas/v1.0.0"

   keyPasswords="secret" />

   <jaas:keystore name="trust"
   path="file:///some/path/truststore.jks
   keystorePassword="secret" />
</blueprint>

我怀疑我在这个配置文件中缺少 ssl.provider 选项。尽管源似乎在寻找某种 URI，但文档并不清楚这是什么期望。我花了很多时间进行搜索，但找不到任何关于提供 CA 服务的公司之外的 SSL 提供商的信息。我不知道这可能在寻找什么 URI。我没有进行撤销检查，所以不是那样。想知道这里可能出了什么问题吗？

Answer 1

几天前我终于解决了这个问题，我想我会记录这个解决方案，以防将来它对任何人有帮助。

问题确实是配置文件中缺少 ssl.provider 字段。需要弄清楚的部分是所需的实际 URI。在我之前的实验中，我缺少 LDAP 的基本 DN。最终，该字段应该看起来像

ssl.provider=ldaps://<somehostname>:<port>/<baseDN>

所以我最终得到的是

<?xml version="1.0" encoding="UTF-8"?>
