     //这里解释一下 OU DC CN的意思

      //因为ldap访问的是树结构的数据库  所有既然是数据库 那就必须要有 数据库名称也就是域名 这里就是用DC表示

      //比如域名是Test.bomb那么必须按照顺序来写 如下 DC=Test,DC=bomb

      //dc下面对应的创建文件夹就是一个组织结构  用OU来表示 OU必须DC的前面

      //CN表示组织结构下的用户名称 CN必须卸载OU的前面

      //主义OU必须是完整的路径 比如hongan是最上面的 下面有个a组织 a下面有个b组织

     //不能直接写OU=b,OU=a,DC=Test,DC=bomb   必须要指明完整的要这样写OU=b,OU=a,OU=hongan，DC=Test,DC=bomb

//否则会报错
