我正在尝试按组名获取所有用户并将其显示在 sharepoint webpart 中.adGroupName 类似于 = "CompanyGroup".
I am trying to get all users by group name and dispalay it in sharepoint webpart. adGroupName something like = "CompanyGroup".
GroupPrincipal grp = GroupPrincipal.FindByIdentity(ctx, IdentityType.Name, adGroupName);
异常:
为了执行此操作,必须在连接上成功绑定
In order to perform this operation a successful bind must be completed on the connection
为什么会这样,我做错了什么?
Why is that and what i am doing wrong?

解决方案是使用代码:
using (HostingEnvironment.Impersonate()) {
