获取Active Directory中的所有用户

标签: vb.net visual-studio-2010 active-directory

我正在尝试获取域中活动目录中所有用户的列表。正在使用以下代码,但似乎不起作用:

Public Function GetAllUsers(ByVal ldapServerName As String) As Hashtable
    'To retrieve list of all  LDAP users

    'This function returns HashTable
    _ldapServerName = ldapServerName

    Dim sServerName As String = "mail"

    Dim oRoot As DirectoryEntry = New DirectoryEntry("LDAP://" & ldapServerName & _
          "/ou=People,dc=mydomainname,dc=com")

    Dim oSearcher As DirectorySearcher = New DirectorySearcher(oRoot)
    Dim oResults As SearchResultCollection
    Dim oResult As SearchResult
    Dim RetArray As New Hashtable()

    Try

        oSearcher.PropertiesToLoad.Add("uid")
        oSearcher.PropertiesToLoad.Add("givenname")
        oSearcher.PropertiesToLoad.Add("cn")
        oResults = oSearcher.FindAll

        For Each oResult In oResults

            If Not oResult.GetDirectoryEntry().Properties("cn").Value = "" Then
                RetArray.Add(oResult.GetDirectoryEntry().Properties("uid").Value, _
                  oResult.GetDirectoryEntry().Properties("cn").Value)
            End If

        Next

    Catch e As Exception

        'MsgBox("Error is " & e.Message)
        Return RetArray

    End Try

    Return RetArray

End Function

为了确保我正确地执行此操作,ldapServerName应该是我登录的域名,当我 CTRL + alt 时+ del ,对吗?或者那会进入dc=mydomainname部分吗?

上述代码中的第一个错误是_ldapServerName = ldapServerName

错误说是:

 Error 14 '_ldapServerName' is not declared. It may be inaccessible due to its protection level.

    ' create a domain context for your default domain
    Dim ctx As New PrincipalContext(ContextType.Domain)

    ' define a "query-by-example" to search for
    Dim searchExample As Principal = New UserPrincipal(ctx)

    ' define the principal searcher, based on that example principal
    Dim ps As New PrincipalSearcher(searchExample)

    ' loop over all principals found by the searcher
    For Each p As Principal In ps.FindAll()
        ' do whatever you want to do with the principals
        Console.WriteLine("Type: {0} / Name: {1}", p.StructuralObjectClass, p.Name)
    Next

更新2

当我使用IE并输入ldap://mydomainhere.com/ou=Users

我什么都没得到......但是当我这样做时:

 ldap://mydomainhere.com

然后我弹出“找人”框。所以我知道我有正确的LDAP,但不确定为什么其他信息阻止它工作......

如果您的AD不是太大,并且您使用的是.NET 3.5或更高版本(我认为,因为您使用的是VS2010),您应该可以编写如下内容:

// create a domain context for your default domain
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

// define a "query-by-example" to search for
Principal searchExample = new UserPrincipal(ctx);

// define the principal searcher, based on that example principal
PrincipalSearcher ps = new PrincipalSearcher(searchExample);

// loop over all principals found by the searcher
foreach(Principal p in ps.FindAll())
{
    // do whatever you want to do with the principals
    Console.WriteLine("Type: {0} / Name: {1}", p.StructuralObjectClass, p.Name);
}

PS:为了“找到您的LDAP”,您可以查看我的C#,名为BeaverTail的开源LDAP浏览器 - 免费提供(C#,. NET) 1.1时间表)

更新:如果要选择特定位置(及其子容器)中的所有用户,可以通过在域上下文中指定“起点”来执行此操作:

// create a domain context for your default domain, 
// starting at a specific location
PrincipalContext ctx = 
   new PrincipalContext(ContextType.Domain, "YOURDOMAIN", 
                        "OU=Personnel,OU=Users,DC=YourDomain,DC=com");

// define a "query-by-example" to search for
Principal searchExample = new UserPrincipal(ctx);

// define the principal searcher, based on that example principal
PrincipalSearcher ps = new PrincipalSearcher(searchExample);

// loop over all principals found by the searcher
foreach(Principal p in ps.FindAll())
{
    UserPrincipal up = (p as UserPrincipal);

    if(up != null)
    {
       // do whatever you want to do with the principals
       Console.WriteLine("Name: {0} / E-Mail: {1}", up.Name, up.EmailAddress);
    }
}

答案 1 :(得分:1)

CStr(userlist(i).Properties("samAccountName").ToString)

更改为:

userlist(i).GetDirectoryEntry().Properties("givenName").Value

这种改变对我有用

答案 2 :(得分:0)

在我的特定情况下,我不得不使用:

Dim oRoot As DirectoryEntry = New DirectoryEntry("LDAP://CN=Users,DC=YOUR_DOMAIN_NAME_HERE,DC=local")
