Die Bibliothek Novell.Directory.Ldap.NETStandard kann nicht abgefragt werden

Question

Ich muss den Benutzer ein Active Directory nach Namen in .Net Core abfragen lassen. Also baue ich einen Active Directory Search Web API Service.

Ich bin in der Lage, mit der Bind-Anweisung zu verbinden. Aber ich bin nicht in der Lage, Ergebnisse mit meiner Abfrage zurück zu erhalten, obwohl es keinen Fehler gibt.

Ein anderer Programmierer hat mir einen Code geschickt, den er in anderen Anwendungen benutzt. Es verwendet jedoch das DirectoryEntry-Objekt, das in .NET Core nicht verfügbar ist.

So versuche ich, die Novell.Directory.Ldap.NetStandard-Bibliothek zu verwenden. Hier

ist der Code, der andere Entwickler der mich gesandt hat:

public static List<UserProfileModel> GetADUsers(string alias) 
    { 
     List<UserProfileModel> users = new List<UserProfileModel>(); 

     if (alias == null || alias.Trim().Equals("")) 
     { 
      return users; 
     } 

     try 
     { 
      // Ad path LDAP://ourOrg.gov/CN=Users,DC=ourOrg,DC=gov 
      DirectoryEntry de2 = new DirectoryEntry(ConfigurationManager.AppSettings["AD_Path"], ConfigurationManager.AppSettings["AD_User"], ConfigurationManager.AppSettings["AD_Password"]); 
      de2.Path = ConfigurationManager.AppSettings["AD_Path"]; 

      de2.AuthenticationType = AuthenticationTypes.Secure; 

      DirectorySearcher deSearch = new DirectorySearcher(); 

      deSearch.SearchRoot = de2; 
      deSearch.Filter = "(samaccountname=*" + alias + "*)"; 

      LOGGER.Debug(String.Format("Active Directory Search Filter {0}", deSearch.Filter)); 

      SearchResultCollection results = deSearch.FindAll(); 
      String raw = ""; 

      LOGGER.Debug(String.Format("Active Directory Search Result Counts {0}", results.Count)); 

      if (results.Count > 0) 
      { 
       foreach (SearchResult item in results) 
       { 
        UserProfileModel userProfileModel = new UserProfileModel(); 

        userProfileModel.Name = GetADProperty("name", item); 
        userProfileModel.email = GetADProperty("mail", item); 
        userProfileModel.identity = GetADProperty("userPrincipalName", item); 
        userProfileModel.first_name = GetADProperty("givenName", item); 
        userProfileModel.last_name = GetADProperty("sn", item); 
        users.Add(userProfileModel); 
        raw = String.Format("{0}/n{1}", raw, userProfileModel.ToString()); 
       } 
       LOGGER.Debug(String.Format("Active Directory Search Resuts ToString: {0}", raw)); 
      } 
     } 
     catch (Exception e) 
     { 
      LOGGER.Error("Unable to Query Active Directory", e); 
     } 

     return users; 
    } 

Ich brauche dies in Novell LDAP-Bibliothek zu übersetzen.

Hier ist mein Versuch:

[HttpGet] 
    public async Task<List<UserProfileModel>> GetByName(string alias) 
    { 

     int ldapPort = LdapConnection.DEFAULT_PORT; 
     string ldapHost = "ourOrg.gov"; 
     string loginDn = @"ourOrg\myName"; 
     string password = "myPass"; 

     List<UserProfileModel> users = new List<UserProfileModel>(); 

     if (alias == null || alias.Trim().Equals("")) 
     { 
      return users; 
     } 

     try 
     { 
      using (var con = new LdapConnection()) 
      { 
       con.Connect(ldapHost, ldapPort); 
       con.Bind(loginDn, password); 

       LdapSearchResults results = con.Search(
        "cn=users,dc=ourOrg,dc=gov", 
        LdapConnection.SCOPE_ONE, 
        "samaccountname=*", 
        null, 
        false); 

       // NO RESULTS:(
      } 

      return users; 
     } 
     catch(Exception ex) 
     { 
      throw ex; 
     } 

    } 

Ich habe keinen Fehler. Aber es gibt 0 Ergebnisse.

Ich hatte ursprünglich diesen Teil:

"samaccountname = *",

wie:

"samaccountname = {alias}",

aber ich versuche nur, um an dieser Stelle Ergebnisse zu erhalten.
