我在Windows 2008 R2上安装了MS Active Directory。我在默认组默认的用户组下创建了两个Admins and Devs组。我在Admins组中添加了两个具有管理员权限的用户和一个Devs组中的一个用户。我正在尝试使用admininstrator用户'kishank'登录，但我收到以下错误：
[LDAP：错误代码49 - 80090308：LdapErr：DSID-0C0903A9，评论：AcceptSecurityContext错误，数据52e，v1db1]
我搜索了此错误，其中显示无效的用户或密码。这是链接：It gives description about error code 49 DSID 0C0903A9. It says that the error only occurs on MS AD servers.
我还读过某个地方，我应该取消选中“密码永不过期”复选框，但没有运气。
我的配置文件如下：
