Question

我在执行期间遇到问题，我认为连接器的ldap.init参数可能有问题。在执行此组件期间，故障流程会产生错误：

似乎我错过了一些参数，因为Authenticate.java中发生了错误。查看line 55 in the GitHub，现在查看我的部分XML：

<api context="/SampleContextLdapContext" name="SampleLdapName" xmlns="http://ws.apache.org/ns/synapse">
  <resource methods="POST" protocol="http">
    <inSequence>
      <log description="" separator=",">
        <property name="Message Flow" value="LDAP SAMPLE TEST"/>
        <property expression="//myvar/text()" name="myVarValue"/>
      </log>
      <ldap.init>
        <providerUrl>ldap://192.168.2.10:389/</providerUrl>
        <securityPrincipal>aqlbras\willian</securityPrincipal>
        <securityCredentials>SamplePassword</securityCredentials>
      </ldap.init>

当我没有配置 providerUrl 时，错误发生在第54行，这意味着name参数对于此标记是正确的，但对于 securityPrincipal 标记是不正确的（您可以在GitHub存储库中看到以确保）。

我错过了什么或者代码中有错误吗？

创建一个接收用户名和密码的休息网络服务。
使用参数在LDAP目录中进行身份验证，并返回一些自己的属性/属性。

Answer 1

我认为问题在于您的securityPrincipal不是LDAP专有名称（DN）。例如，它看起来像uid=willian,ou=people,dc=aqlbras,dc=com

如果您没有设置providerUrl，我会对您收到NullPointerException感到惊讶。这基本上是LDAP服务器的主机名/端口信息。

LDAP连接器不读取参数
