Question

我正在使用vb.net，我想检查Active Directory中是否存在特定用户。如果是，我想显示特定用户的详细信息。怎么做？

用户登录凭据通过文本框控件传递

我的代码：

 Dim de As DirectoryEntry = GetDirectoryEntry()
 Dim ds As DirectorySearcher = New DirectorySearcher(de)
  ds.Filter = "(&(objectClass=txt1.text))"

    ' Use the FindAll method to return objects to SearchResultCollection.
    results = ds.FindAll()

Public Shared Function GetDirectoryEntry() As DirectoryEntry
    Dim dirEntry As DirectoryEntry = New DirectoryEntry()
    dirEntry.Path = "LDAP://ss.in:389/CN=Schema,CN=Configuration,DC=ss,DC=in"
    dirEntry.Username = "ss.in\ssldap"
    dirEntry.Password = "ss@123"
    'Dim searcher As New DirectorySearcher
    'searcher.SearchRoot = dirEntry
    Return dirEntry
End Function

我传递密码的地方。这段代码是否正确？我是AD的新手。请帮我这样做？

如果您使用的是.NET 3.5及更高版本，则应查看System.DirectoryServices.AccountManagement（S.DS.AM）命名空间。在这里阅读所有相关内容：

基本上，您可以定义域上下文并轻松在AD中查找用户和/或组：

// set up domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

// find a user
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, "SomeUserName");

if(user != null)
{
   // your user exists - do something here....      
}
else
{
   // your user in question does *not* exist - do something else....
}

或者在VB.NET中：

' set up domain context
Dim ctx As New PrincipalContext(ContextType.Domain)

' find a user
Dim user As UserPrincipal = UserPrincipal.FindByIdentity(ctx, "SomeUserName")

If user IsNot Nothing Then
   ' your user exists - do something here....               
Else
   ' your user in question does *not* exist - do something else....
End If

新的S.DS.AM让您可以轻松地与AD中的用户和群组一起玩！
