代码中枚举用户所在所有群组时，提示错误：An error occurred while enumerating the groups. The group could not be found

Question





在通过System.DirectoryServices.AccountManagement下的PrincipalContext调用GetAuthorizationGroups时，抛出异常：An error occurred while enumerating the groups. The group could not be found.但只是一部分用户在访问时会出现异常，不是所有的。请问该问题是什么原因引发的，寻求解决方案，谢谢！  代码：PrincipalContext principalContext = new PrincipalContext(ContextType.Domain);             UserPrincipal userPrincipal = UserPrincipal.FindByIdentity(principalContext,IdentityType.SamAccountName,"userLoginName");                     PrincipalSearchResult<Principal> list = userPrincipal.GetAuthorizationGroups();                                                                       











Answer 1

Hi,

>>" 但只是一部分用户在访问时会出现异常  ".

会不会是这部分用户的权限导致这样问题。你有尝试过赋予相同的用户权限吗？ 这个Domain，应该就是涉及到权限的问题。

如果有什么最新的情况，请随时联系我们。

Answer 2

Hi,

      我做过测试，抽取和我同一个部门的几个同事帐号来访问，发现有一个也提示这个异常，其他几个没有问题，包括我自己的。

是否还有其他测试方法来定位？

Answer 3

这个用户和其他用户有什么不同的地方吗？ 这种问题最难定位了，因为有的好使，有的不好使。

你有debug你的程序吗？具体在哪里出现错误。

Answer 4

用户之间没有大的区别，就是所在群组有些不同而已，但这个应该不会影响，错误是在

PrincipalSearchResult<Principal> list = userPrincipal.GetAuthorizationGroups();    这块抛出:

An error occurred while enumerating the groups. The group could not be found

Answer 5

Hi,

从这些错误信息，我们就可以知道，是这个群组没有找到，所以先确认能找到你的群组信息。是不是这个群组有特殊的权限吗？

Best Regards,
