C# Active Directory and Accounts Locked Out RRS feed

  • Question

  • I am trying to see if an account is locked out but I cant figure out what I am doing wrong. If anyone has a moment Below is what i am attempting. I know the value I am looking for is 1 or 0 but when I go through the locals and find lockoutTime the value is {System.__ComObject}. Any advice would help

    long lockedOut;
    lockedOut = (long)result.GetDirectoryEntry().Properties["lockoutTime"][0];

  • Tried using an object as well. no better luck.

    object comObj;
    comObj = result.GetDirectoryEntry().Properties["lockoutTime"][0];

  • Hi Quarinteen,

    Thank you for posting here and sorry for late reply.

    Based on my test, the value of "lockoutTime" property is null. But you could set the Value. Set 0 to unlock.

    Here is the code I used to get the value Empty.

     static void Main(string[] args)
                string strUserName = "XXXX";//UserName
                string strPath = "LDAP://DC=xxxx,DC=xxxx,DC=xxxx,DC=xxxx";
                DirectoryEntry usr = new DirectoryEntry(strPath);
                DirectorySearcher searcher = new DirectorySearcher(usr);
                searcher.Filter = "(SAMAccountName=" + strUserName + ")";
                searcher.CacheResults = false;
                SearchResult result = searcher.FindOne();
                var lockedOut = result.Properties["lockoutTime"];
                // Unlock("LDAP://DC=xxxx,DC=xxxx,DC=xxxx,DC=xxxx");

    And you could set the lockoutTime value to 0 to unlock account.

     static void Main(string[] args)
            public static void Unlock(string userDn)
                    DirectoryEntry uEntry = new DirectoryEntry(userDn);
                    uEntry.Properties["LockOutTime"].Value = 0; //unlock account
                    uEntry.CommitChanges(); //may not be needed but adding it anyways
                catch (System.DirectoryServices.DirectoryServicesCOMException E)
                    //DoSomethingWith --> E.Message.ToString();

    For more details, you could refer to the article in code project.
