Question

是否可以从LDAP中检索所有属性/值的列表而不指定，如果可以，这怎么可能？

Answer 1

我获取了DirectoryEntry类对象的所有参数列表。我希望它会有所帮助：

objectClass = System.Object[]
cn = Administrator
sn = Kwiatek (Last name)
c = PL (Country Code)
l = Warszawa (City)
st = Mazowieckie (Voivodeship)
title = .NET Developer
description = Built-in account for administering the computer/domain
postalCode = 00-000
postOfficeBox = Warszawa Ursynów
physicalDeliveryOfficeName = Wojskowa Akademia Techniczna
givenName = Piotr (First name)
distinguishedName = CN=Administrator,CN=Users,DC=helpdesk,DC=wat,DC=edu
instanceType = 4
whenCreated = 2012-11-23 06:09:28
whenChanged = 2013-02-23 13:24:41
displayName = Piotr Kwiatek (Konto administratora)
uSNCreated = System.__ComObject
memberOf = System.Object[]
uSNChanged = System.__ComObject
co = Poland
company = HELPDESK
streetAddress = Kaliskiego 2
wWWHomePage = http://www.piotr.kwiatek.org
name = Administrator
objectGUID = System.Byte[]
userAccountControl = 512
badPwdCount = 0
codePage = 0
countryCode = 616
badPasswordTime = System.__ComObject
lastLogoff = System.__ComObject
lastLogon = System.__ComObject
logonHours = System.Byte[]
pwdLastSet = System.__ComObject
primaryGroupID = 513
objectSid = System.Byte[]
adminCount = 1
accountExpires = System.__ComObject
logonCount = 178
sAMAccountName = Administrator
sAMAccountType = 805306368
objectCategory = CN=Person,CN=Schema,CN=Configuration,DC=helpdesk,DC=wat,DC=edu
isCriticalSystemObject = True
dSCorePropagationData = System.Object[]
lastLogonTimestamp = System.__ComObject
mail = spam@kwiatek.org
nTSecurityDescriptor = System.__ComObject

在这里你有代码：

string currentUserSid = WindowsIdentity.GetCurrent().User.Value;

            PrincipalContext ctx = new PrincipalContext(
                ContextType.Domain,
                "helpdesk.wat.edu");

            UserPrincipal up = UserPrincipal.FindByIdentity(
                ctx, IdentityType.Sid,
                currentUserSid);

            /*
             * 
             */
            DirectoryEntry entry = up.GetUnderlyingObject() as DirectoryEntry;
            PropertyCollection props = entry.Properties;

            /*
             * 
             */
            foreach (string propName in props.PropertyNames)
            {
                if (entry.Properties[propName].Value != null)
                {
                    Console.WriteLine(propName + " = " + entry.Properties[propName].Value.ToString());
                }
                else
                {
                    Console.WriteLine(propName + " = NULL");
                }
            }


            Console.ReadKey();

Answer 2

指定“*”作为要返回的属性列表中的唯一值。

如果您还想要操作属性，请在列表中添加“+”。

Answer 3

    // This will list ALL the properties from AD (between 200 and 800..or more)
    // If someone has a solution for non AD servers please post it!

    List<String> properties = new List<String>();
    IPAddress[] ips = Dns.GetHostAddresses(Server).Where(w => w.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork).ToArray();
    if (ips.Length > 0)
    {
        DirectoryContext directoryContext = new DirectoryContext(DirectoryContextType.DirectoryServer, ips[0].ToString() + ":389", Username, Password);
        ActiveDirectorySchema adschema = ActiveDirectorySchema.GetSchema(directoryContext);
        ActiveDirectorySchemaClass adschemaclass = adschema.FindClass("User");

        // Read the OptionalProperties & MandatoryProperties
        ReadOnlyActiveDirectorySchemaPropertyCollection propcol = adschemaclass.GetAllProperties();

        foreach (ActiveDirectorySchemaProperty schemaProperty in propcol)
            properties.Add(schemaProperty.Name.ToLower());
    }

Answer 4

单独检索“所有属性”，就目录而言，这是没有意义的。你的意思是：

在SCHEMA中描述的所有用户可能的属性
所有用户属性值
所有用户和操作属性

我并没有注意这样一个事实：某些用户属性可以是只读的，而其他用户属性只能用特定的值写入。我添加了获取内容的方法。

@Ghostfire提供了用于检索所有用户属性和操作属性的解决方案。

DirectoryEntry deUser = new DirectoryEntry("LDAP://WM2008R2ENT:389/CN=AUser,OU=MonOu,DC=dom,DC=fr");


foreach (string property in deUser.Properties.PropertyNames)
{
  Console.WriteLine("\t{0} : {1} ", property, deUser.Properties[property][0]);
}

但请记住，在LDAP搜索中，最好的方法是提供您想要检索的属性：

/* Connection to Active Directory
 */
DirectoryEntry deBase = new DirectoryEntry("LDAP://WM2008R2ENT:389/dc=dom,dc=fr");

/* Directory Search
 */
DirectorySearcher dsLookFor = new DirectorySearcher(deBase);
dsLookFor.Filter = "(sn=users)";
dsLookFor.SearchScope = SearchScope.Subtree;
dsLookFor.PropertiesToLoad.Add("cn");
dsLookFor.PropertiesToLoad.Add("givenName");
dsLookFor.PropertiesToLoad.Add("telephoneNumber");

dsLookFor.Sort = new SortOption("givenName", SortDirection.Descending);
dsLookFor.VirtualListView = new DirectoryVirtualListView(1, 0, 2);
SearchResultCollection srcUsers = dsLookFor.FindAll();

Answer 5

您可以使用DirectoryEntry生成属性列表，您必须使用每个属性列表来查看属性列表。

    DirectoryEntry objADAM = default(DirectoryEntry);
    string properties = string.Empty;
    foreach (string property in objADAM.Properties.PropertyNames)
    {
        properties += property + ", ";
    }

当涉及到C＃和Active Directory时，你总是可以参考 ~~http://www.codeproject.com/KB/system/everythingInAD.aspx~~ 。

ADSI Edit是一个很好的工具，可以帮助您找出问题所在。在这种情况下，您需要使用架构数据。当您打开ADSI Edit时，选择“连接到...”，然后为众所周知的命名上下文选择“ Schema” ...，现在您可以看一下不同的模式类：（subSchema，classSchema，attributeSchema） ...

棘手的是，知道您需要选择一个classSchema，然后获取其“ schemaIDGUID” ...然后在所有attributeSchema上进行搜索并在“ schemaIDGUID”上进行过滤

例如如果您选择查看“ CN =用户”，则会注意到schemaIDGUID == bf967aba-0de6-11d0-a285-00aa003049e2

然后，如果您选择查看“ CN = Pwd-Last-Set”，则会注意到schemaIDGUID匹配。...

话虽如此，使用ActiveDirectorySchemaClass可能要容易得多（正如David回答的那样），但是我感觉要分享一些知识。

Answer 7

有关所有可能属性的列表，您应该查看查询给定objectClass的模式。
