c# - 如何以编程方式更改 Active Directory 密码

Question

我有一组要创建的测试帐户，但这些帐户将设置为在第一次登录时需要更改密码。我想用 C# 编写一个程序来检查测试帐户并更改密码。

Answer 1

一旦找到正确的 UserPrincipal 对象，您就可以使用UserPrincipal类的SetPassword方法，前提是您有足够的权限。使用FindByIdentity查找有问题的主体对象。

using (var context = new PrincipalContext( ContextType.Domain ))
{
  using (var user = UserPrincipal.FindByIdentity( context, IdentityType.SamAccountName, userName ))
  {
      user.SetPassword( "newpassword" );
      // or
      user.ChangePassword( "oldPassword", "newpassword" );

      user.Save();
  }
}

这是一个很棒的 Active Directory 编程快速参考：

Howto：（几乎）通过 C# 在 Active Directory 中的所有内容

请参阅接近末尾的密码重置代码。

public void ResetPassword(string userDn, string password)
{
    DirectoryEntry uEntry = new DirectoryEntry(userDn);
    uEntry.Invoke("SetPassword", new object[] { password });
    uEntry.Properties["LockOutTime"].Value = 0; //unlock account

    uEntry.Close();
}

试试这个代码。这个对我有用，

public void ChangeMyPassword(string domainName, string userName, string currentPassword, string newPassword)
{
    try
    {
        string ldapPath = "LDAP://192.168.1.xx";
        DirectoryEntry directionEntry = new DirectoryEntry(ldapPath, domainName + "\\" + userName, currentPassword);
        if (directionEntry != null)

        {
            DirectorySearcher search = new DirectorySearcher(directionEntry);
            search.Filter = "(SAMAccountName=" + userName + ")";
            SearchResult result = search.FindOne();
            if (result != null)
            {
                DirectoryEntry userEntry = result.GetDirectoryEntry();
                if (userEntry != null)
                {
                    userEntry.Invoke("ChangePassword", new object[] { currentPassword, newPassword });
                    userEntry.CommitChanges();
                }
            }
        }
    }
    catch (Exception ex)
    {
        throw ex;
    }
}

这是解决方案：

string newPassword = Membership.GeneratePassword(12, 4);    
string quotePwd = String.Format(@"""{0}""", newPassword);    
byte[] pwdBin = System.Text.Encoding.Unicode.GetBytes(quotePwd);    
UserEntry.Properties["unicodePwd"].Value = pwdBin;    
UserEntry.CommitChanges();

Answer 5

可以使用 .NET Framework 2.0 为域帐户设置新密码。请参阅下面的工作代码：

string domainfqdn="mydomain.test.gov" //fqdn of the domain
string ldapPath =GetObjectDistinguishedName (objectClass.user,returnType.distinguishedName, args[0].ToString(),domainfqdn);
ldapPath="LDAP://" + domainfqdn + :389/"+ldapPath;

DirectoryEntry uEntry = new DirectoryEntry(ldapPath,null,null,AuthenticationTypes.Secure);
uEntry.CommitChanges();
Console.WriteLine(ldapPath);
string password="myS3cr3tPass"              
uEntry.Invoke("SetPassword", new object[] { password });
uEntry.Properties["LockOutTime"].Value = 0; //unlock account                
uEntry.CommitChanges();
uEntry.Close();             

检查uEntry的参数非常重要，代码将在当前线程安全上下文下运行，除非指定了空值

public void ResetPassword(string userName, string Password, string newPassword)
{
    try
    {
        DirectoryEntry directoryEntry = new DirectoryEntry(Path, userName, Password);

        if (directoryEntry != null)
        {
            DirectorySearcher searchEntry = new DirectorySearcher(directoryEntry);
            searchEntry.Filter = "(samaccountname=" + userName + ")";
            SearchResult result = searchEntry.FindOne();
            if (result != null)
            {
                DirectoryEntry userEntry = result.GetDirectoryEntry();
                if (userEntry != null)
                {
                    userEntry.Invoke("SetPassword", new object[] { newPassword });
                    userEntry.Properties["lockouttime"].Value = 0;
                }
            }
        }
    }
    catch (Exception ex)
    {
        Log.Error("Password Can't Change:" + ex.InnerException.Message);
    }
}
