GroupPrincipal方法FindByIdentity抛出奇怪的异常
本文关键字:异常 方法 FindByIdentity GroupPrincipal | 更新日期: 2023-09-27 18:13:27
我试图通过组名获得所有用户并在sharepoint webpart中显示它。adGroupName = "CompanyGroup".
GroupPrincipal grp = GroupPrincipal.FindByIdentity(ctx, IdentityType.Name, adGroupName);
异常:要执行此操作,必须在连接
上成功完成绑定。
为什么是这样,我做错了什么?

答案在博客中找到:
http://sharepoint-tweaking.blogspot.com/2007/12/impersonation-in-aspnet-causes.html解决方案是使用代码:
using (HostingEnvironment.Impersonate()) {
// This code runs as the application pool user
DirectorySearcher searcher ...
}
您是否使用这样的东西来获取您的上下文?
/* Retreiving a principal context
*/
PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "MachineIP:389", "dc=dom,dc=fr", "jpb", "root.123");
您可以将MachineIP替换为您的域名或您的DC之一的DNS名称。
