Question

我无法判断服务器上是否存在凭据/ SSL问题或LDAP配置问题。我尝试访问本地版本，我没有问题（然后再次本地Ldap和服务器设置有点不同）。绝对不会关闭套接字，因为我们在处理系统中使用该URL并且它没有关闭。

此行的代码失败：

NamingEnumeration<?> namingEnum = ctx.search("dc=barney,dc=com", "(objectclass=person)", getSimpleSearchControls());

代码块：

final String ldapAdServer = "ldap://myspecialhost.barney.us:389";                               
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.PROVIDER_URL, ldapAdServer);    
LdapContext ctx = new InitialLdapContext(env, null);
            ctx.setRequestControls(null);
   NamingEnumeration<?> namingEnum = ctx.search("dc=barney,dc=com", "(objectclass=person)", getSimpleSearchControls());

堆栈跟踪在这里：

编辑1：我尝试使用不同的网址，我得到一个连接超时。这个新网址是否更正确并且我可能更接近正确的网址？

编辑2：
