use*_*881 6 c# asp.net iprincipal principalcontext
我正在尝试验证用户是否在“ TestGroup”组中。该用户是“ TestGroup”组的一部分,即使我正在获取retval = false @line(retVal = user.IsMemberOf(groupPrincipal);),并且在事件查看器中,它也将msg显示为“用户名或密码不正确” ”。
你能帮我吗

UserPrincipal.IsMemberOf(GroupPrincipal) 似乎适用于某些组,而不适用于其他组。在我的域中,它适用于域\开发人员(自定义组),但不适用于域\域用户。去搞清楚。我停止了调试器中的代码并检查了 Domain Users 组的成员列表,并在其中找到了我的用户,但 IsMemberOf 仍然返回 false。但是,我发现如果我循环遍历 GroupPrincipal.Members 中的 UserPrincipal 对象集合,我可以通过将集合中的 UserPrincipal 与我正在搜索的 UserPrincipal 进行比较来进行检查。蹩脚的,但我能找到的唯一可靠的解决方案。
示例代码:
string sAccountToCheckSID = upAccountToCheck.Sid.Value;
foreach(UserPrincipal up in gpKnownAccountToCheck.Members)
{
string sKnownSIDInGroup = up.Sid.Value;
if(sKnownSIDInGroup.Equals(sAccountToCheckSID))
{
userMatchingUserObject = userKnownUser;
return true;
}
}

所以我不知道为什么。但这就是我的工作。
