查找用户帐户是否在 AD 中启用或禁用

Question

我需要确定用户帐户在 AD 中是启用还是禁用。

我找不到标志或属性 "userAccountControl"。这可以使用 USERPRINCIPAL class 来实现吗？

        drop_persona1.Items.Clear();
        string valor = drop_area.SelectedValue;

            List<string> allUsers = new List<string>();

       PrincipalContext ctx2 = new PrincipalContext(ContextType.Domain, "xxxxxxxx",
                                                        valor);


            UserPrincipal qbeUser2 = new UserPrincipal(ctx2);
            qbeUser2.Enabled = true; // activo para autenticacion

            PrincipalSearcher srch2 = new PrincipalSearcher(qbeUser2);
            srch2.QueryFilter = qbeUser2;    

            foreach (var found2 in srch2.FindAll().OrderBy(x=> x.DisplayName))
            {
                ListItem lst_user = new ListItem(found2.DisplayName, found2.SamAccountName);
                drop_persona1.Items.Insert(drop_persona1.Items.Count, lst_user);
            }

        //}
    }

此致

Answer 1

我没有测试过这个答案，但我相信它应该有效。

1) 使用 -

获取目录条目对象

UserPrincipal qbeUser2 = new UserPrincipal(ctx2);
var dirEntry = qbeUser2.GetUnderlyingObject() as DirectoryEntry;

2) 然后通过 -

检查帐户禁用状态

var status = IsAccountDisabled(dirEntry);
public static bool IsAccountDisabled(DirectoryEntry user)
        {
            string Uac = "userAccountControl";
            if (user.NativeGuid == null) return false;

            if (user.Properties[Uac] != null && user.Properties[Uac].Value != null)
            {
                var userFlags = (UserFlags)user.Properties[Uac].Value;
                return userFlags.Contains(UserFlags.AccountDisabled);
            }

            return false;
        }

3) 这是枚举 UserFlags -

[Flags]
public enum UserFlags
{
    // Reference - Chapter 10 (from The .NET Developer's Guide to Directory Services Programming)

    Script = 1,                                     // 0x1
    AccountDisabled = 2,                            // 0x2
    HomeDirectoryRequired = 8,                      // 0x8
    AccountLockedOut = 16,                          // 0x10
    PasswordNotRequired = 32,                       // 0x20
    PasswordCannotChange = 64,                      // 0x40
    EncryptedTextPasswordAllowed = 128,             // 0x80
    TempDuplicateAccount = 256,                     // 0x100
    NormalAccount = 512,                            // 0x200
    InterDomainTrustAccount = 2048,                 // 0x800
    WorkstationTrustAccount = 4096,                 // 0x1000
    ServerTrustAccount = 8192,                      // 0x2000
    PasswordDoesNotExpire = 65536,                  // 0x10000 (Also 66048 )
    MnsLogonAccount = 131072,                       // 0x20000
    SmartCardRequired = 262144,                     // 0x40000
    TrustedForDelegation = 524288,                  // 0x80000
    AccountNotDelegated = 1048576,                  // 0x100000
    UseDesKeyOnly = 2097152,                        // 0x200000
    DontRequirePreauth = 4194304,                   // 0x400000
    PasswordExpired = 8388608,                      // 0x800000 (Applicable only in Window 2000 and Window Server 2003)
    TrustedToAuthenticateForDelegation = 16777216,  // 0x1000000
    NoAuthDataRequired = 33554432                   // 0x2000000
}

这是在AD上测试的完整代码。它在我的测试中运行良好。

Answer 2

如果您只需要查明用户是启用还是禁用，您可以使用以下方法更简单一些：

PrincipalContext context = new PrincipalContext(ContextType.Domain);
UserPrincipal user = UserPrincipal.FindByIdentity(context, IdentityType.SamAccountName, searchTextBox.Text.Trim());

if(user.Enabled == true) MessageBox.Show("Account enabled!");
else MessageBox.Show("Account disabled!");

查找用户帐户是否在 AD 中启用或禁用

find if user account is enabled or disabled in AD
