How to login to Active Directory C# winforms?

Question

Active Directory

Good afternoon!
There is a self-written EDMS (C# winforms) it is necessary to organize authorization through AD.
Question:
How to implement?
The following information needs to be retrieved from AD:

• Login
  
• Full Name
  
• Password (if possible)
  
• Groups in which he (user) is
  

Request:
Push to Russian-language sources on this topic

Answer 1

System.DirectoryServices.AccountManagement - you won't find a more suitable set of classes for your task. An article with auto-translation, so if nothing is clear at all, take this namespace and drive it into Google. I advise you to start correcting the need for Russian-language sources as soon as possible.

Answer 2

Here is my example of a similar one from one old project, it returns the full name, by login in AD:

private const string Domain = "<b>DOMAINNAME</b>";
static readonly DirectoryEntry Entry = new DirectoryEntry("LDAP://" + Domain);
static readonly DirectorySearcher Dsearch = new DirectorySearcher(Entry);
static SearchResultCollection _sResultSetCol;
public string GetAdFIOfromLogin(string fio)
        {
            try
            {
                fio = fio;
                Dsearch.Filter = "(&(<b>samaccountname</b>=" + fio + "))";
                _sResultSetCol = Dsearch.FindAll();
                try
                {
                    foreach (SearchResult sResultSet in _sResultSetCol)
                    {
                        if (GetProperty(sResultSet, "samaccountname") == fio)
                        {
                            return GetProperty(sResultSet, "<b>name</b>");
                        }
                    }
                }
                catch (Exception e)
                {

                    return e.Message;
                }
            }
            catch (Exception e)
            {
                return e.Message;
            }
            return "";
        }
