  Cannot retreive all the groups from an ldap path and a user

  Dec 23, 2010 04:00 PM|LINK

  what i want to do is to retreive all the groups from an ldap path .... i am able to retreive a certain number of groups but i came to know that these are not all the groups....so i need a way to retreive all the groups including base,sub and all...how can i do this?????

  
  

  Similarly i am retrieving all the groups of a user where also i fera i am not retreiving all the groups  ...

  i am pasting both of the codes so please guide me if i am wrong.....

  
  

  For all the groups in a path...........

  public List<string> GetGroups()
          {
  
              SqlConnection conn_ldap = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Database_OR.mdf;Integrated Security=True;User Instance=True");
              conn_ldap.Open();
              String Select_cmd_ldap = "select LDAP_Address,Access_ID,Access_Password  from LDAPAddress_Table ";
              SqlCommand cmd_ldap = new SqlCommand(Select_cmd_ldap, conn_ldap);
              SqlDataAdapter DA_ldap = new SqlDataAdapter(cmd_ldap);
              DataSet DS_ldap = new DataSet();
              DA_ldap.Fill(DS_ldap);
              conn_ldap.Close();
              String Username = DS_ldap.Tables[0].Rows[0]["Access_ID"].ToString();
              String Password = DS_ldap.Tables[0].Rows[0]["Access_Password"].ToString();
              String Address = DS_ldap.Tables[0].Rows[0]["LDAP_Address"].ToString();
              DirectoryEntry objADAM = default(DirectoryEntry);
              // Binding object.
              DirectoryEntry objGroupEntry = default(DirectoryEntry);
              // Group Results.
              DirectorySearcher objSearchADAM = default(DirectorySearcher);
              // Search object.
              SearchResultCollection objSearchResults = default(SearchResultCollection);
              // Results collection.
              string strPath = null;
              // Binding path.
              List<string> result = new List<string>();
              // Construct the binding string.
              strPath = Address;
              //Change to your ADserver
              // Get the AD LDS object.
              try
              {
                  objADAM = new DirectoryEntry(strPath);
                  objADAM.Username = Username;
                  objADAM.Password = Password;
                  objADAM.RefreshCache();
              }
              catch (Exception e)
              {
                
              }
  
              // Get search object, specify filter and scope,
              // perform search.
              try
              {
                  objSearchADAM = new DirectorySearcher(objADAM);
                  objSearchADAM.Filter = "(&(objectClass=group))";
                  objSearchADAM.SearchScope = SearchScope.Subtree;
                  objSearchResults = objSearchADAM.FindAll();
              }
              catch (Exception e)
              {
                
              }
  
              // Enumerate groups
              try
              {
                  if (objSearchResults.Count != 0)
                  {
                      // SearchResult objResult = default(SearchResult);
                      foreach (SearchResult objResult1 in objSearchResults)
                      {
                          objGroupEntry = objResult1.GetDirectoryEntry();
                          result.Add(objGroupEntry.Name);
                      }
  
                  }
                  else
                  {
                   //   throw new Exception("No groups found");
                  }
              }
              catch (Exception e)
              {
                 // throw new Exception(e.Message);
              }
  
              return result;
          }

  
  

  For groups of a user:

  try
              {
                  DirectoryEntry obEntry = new DirectoryEntry(Address);                
                  obEntry.Username = Login_Xconnect.UserName;
                  obEntry.Password = Login_Xconnect.Password;
                 
                  obEntry.RefreshCache();
                  DirectorySearcher srch = new DirectorySearcher(obEntry, "(sAMAccountName=" + strUser + ")");
                 
                  // DirectorySearcher srch1= new DirectorySearcher(obEntry,
                  SearchResult res = srch.FindOne();
                  if (null != res)
                  {
                      DirectoryEntry obUser = new DirectoryEntry(res.Path);
                      obUser.Username = ID;
                      obUser.Password = Password;
                      object obGroups = obUser.Invoke("Groups");
                      foreach (object ob in (IEnumerable)obGroups)
                      {
                          // Create object for each group.
                          DirectoryEntry obGpEntry = new DirectoryEntry(ob);
                          obGpEntry.Username = ID;
                          obGpEntry.Password = Password;
                          groups.Add(obGpEntry.Name);
                      }
                  }
              }
  
              catch (Exception ex)
              {
                  Trace.Write(ex.Message);
              }
              return groups;

  
  

  
  

  As i said there is no exception but it doesnt give all the groups so please let me know how else can i do this...

  
  

  Thanks

  You can try to use SizeLimit or PageSize or try to use enumerate as shown here
