GroupPrincipal方法FindByIdentity抛出奇怪的exception
我试图通过组名获取所有用户并在sharepoint webpart中显示它。 adGroupName类似=“CompanyGroup”。
GroupPrincipal grp = GroupPrincipal.FindByIdentity(ctx, IdentityType.Name, adGroupName); 例外：
为了执行此操作，必须在连接上完成成功绑定
为什么这样，我做错了什么？
堆栈跟踪：

DirectoryServicesCOMException {“发生操作错误。 r n”}
答案在博客中找到：

解决方案是使用代码：
using (HostingEnvironment.Impersonate()) { // This code runs as the application pool user DirectorySearcher searcher ... }
你是否使用这样的东西来获取你的背景？
/* Retreiving a principal context */ PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "MachineIP:389", "dc=dom,dc=fr", "jpb", "root.123");
您可以使用域名的DNS名称或其中一个DC替换MachineIP。
