您好,
我有以下代码从当前AD创建树:
public static ActiveDirectory GetActiveDirectoryTree(string pathToAD = "")
{
DirectoryEntry objADAM = default(DirectoryEntry);
// Binding object.
DirectoryEntry objGroupEntry = default(DirectoryEntry);
// Group Results.
DirectorySearcher objSearchADAM = default(DirectorySearcher);
// Search object.
SearchResultCollection objSearchResults = default(SearchResultCollection);
// Binding path.
ActiveDirectory result = new ActiveDirectory();
ActiveDirectoryItem treeNode;
// Get the AD LDS object.
try
{
if (pathToAD.Length > 0)
objADAM = new DirectoryEntry();
else
objADAM = new DirectoryEntry(pathToAD);
objADAM.RefreshCache();
}
catch (Exception e)
{
throw e;
}
// Get search object, specify filter and scope,
// perform search.
try
{
objSearchADAM = new DirectorySearcher(objADAM);
objSearchADAM.Filter = "(&(objectClass=group))";
objSearchADAM.SearchScope = SearchScope.Subtree;
objSearchResults = objSearchADAM.FindAll();
}
catch (Exception e)
{
throw e;
}
// Enumerate groups
try
{
if (objSearchResults.Count != 0)
{
//SearchResult objResult = default(SearchResult);
foreach (SearchResult objResult in objSearchResults)
{
objGroupEntry = objResult.GetDirectoryEntry();
result.ActiveDirectoryTree.Add(new ActiveDirectoryItem() { Id = objGroupEntry.Guid, ParentId = objGroupEntry.Parent.Guid, AccountName = objGroupEntry.Name, Type = ActiveDirectoryType.Group, PickableNode = false });
foreach (object child in objGroupEntry.Properties["member"])
{
treeNode = new ActiveDirectoryItem();
var path = "LDAP://" + child.ToString().Replace("/", "\\/");
using (var memberEntry = new DirectoryEntry(path))
{
if (memberEntry.Properties.Contains("sAMAccountName") && memberEntry.Properties.Contains("objectSid"))
{
treeNode.Id = Guid.NewGuid();
treeNode.ParentId = objGroupEntry.Guid;
treeNode.AccountName = memberEntry.Properties["sAMAccountName"][0].ToString();
treeNode.Type = ActiveDirectoryType.User;
treeNode.PickableNode = true;
treeNode.FullName = memberEntry.Properties["Name"][0].ToString();
byte[] sidBytes = (byte[])memberEntry.Properties["objectSid"][0];
treeNode.ObjectSid = new System.Security.Principal.SecurityIdentifier(sidBytes, 0).ToString();
result.ActiveDirectoryTree.Add(treeNode);
}
}
}
}
}
else
{
throw new Exception("No groups found");
}
}
catch (Exception e)
{
throw new Exception(e.Message);
}
return result;
}
问题是使用(var memberEntry = new DirectoryEntry(path))将DomainUsers作为用户返回到此树,我不确定这是否正确?
假设我存储了DomainUsers节点的sidId,然后将其发送到以下方法:
public static Boolean GetActiveDirectoryName(string sidId,out string samAccountName,out string fullName)
{
samAccountName = string.Empty;
fullName = string.Empty;
if (sidId != null && sidId.Length > 0)
{
var ctx = new System.DirectoryServices.AccountManagement.PrincipalContext(ContextType.Domain, null);
using (var up = UserPrincipal.FindByIdentity(ctx, IdentityType.Sid, sidId))
{
samAccountName = up.SamAccountName;
fullName = up.Name;
return true;
}
}
return false;
}
up将被设置为null?如果我在AD中选择另一个用户,那么它工作得很好。我怀疑DomainUsers是一个组,但如何在DirectoryEntry上检查这个?
BestRegards

脱离我的头脑:您是否考虑过检查返回结果的Schema属性?我想你可以使用DirectoryEntry.SchemaEntry.Name
轻松找出一组。如果您的架构条目是一个组,它应该返回group
。
参考:MSDN: DirectoryEntry.SchemaEntry
<小时/> 只是出于好奇和上面代码中的一些主题:
if (pathToAD.Length > 0)
objADAM = new DirectoryEntry();
else
objADAM = new DirectoryEntry(pathToAD);
objADAM.RefreshCache();
如果pathToAD
?,您不想使用Length>0
吗?

警告:
接受的答案使用危险,因为DirectoryEntry.SchemaEntry.Name
可能是任何东西。 (有关更多详细信息,请参见here。
因此,最简单的方法是改为检查objectClass
,如下所示:
// For group check
bool isGroup = entry.Properties["objectClass"]?.Contains("group") == true;
// For user check
bool isUser = entry.Properties["objectClass"]?.Contains("user") == true;
P.S。对于那些想知道我为什么使用== true
的人,请参阅here
