问题描述
我想获取用户所在组的列表.
I want to get the list of groups which the user is in.
这是我的代码:
PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "mydomain.ac.uk", "DC=mydomain,DC=AC,DC=UK", "user", "password"); UserPrincipal user = UserPrincipal.FindByIdentity(ctx, IdentityType.SamAccountName, "MyUser"); PrincipalSearchResult<Principal> results = user.GetGroups(); foreach(Principal p in results) { Response.Write(p.Name); }
运行时,在 Response.Write(p.Name);
System.Runtime.InteropServices.COMException: 指定的目录服务属性或值不存在.
System.Runtime.InteropServices.COMException: The specified directory service attribute or value does not exist.
当我检查结果计数时,它返回 9,第一组是 DomainUsers.
When I checked the count of the results, it returned 9 and the first group is DomainUsers.
如何迭代列表中的所有 9 个组?谢谢.
How can I iterate all 9 groups in the list? Thanks.
以下是我得到的用户列表:
The following is the list of users I get:
推荐答案
当省略 PrincipalContext Class 中描述的 LDAP 容器属性时,运行代码的用户必须对默认的 User 都具有读取权限容器(即 CN=Users,DC=yourDomain,DC=COM)和 Computers 容器(即 CN=Computers,DC=yourDomain,DC=COM).
When omitting the LDAP container property as described in PrincipalContext Class, the user running the code must have read permissions to both the default User Container (i.e. CN=Users,DC=yourDomain,DC=COM) and the Computers Container (i.e. CN=Computers,DC=yourDomain,DC=COM).
如果用户没有所需的权限,您将收到以下错误消息:
If the user does not have the required permissions you will get the following error messages:
指定的目录服务属性或值不存在
The specified directory service attribute or value does not exist
