协议搜索问题

我正在尝试从系统重写搜索。目录服务到System.DirectoryServices.Protocol

在S.DS中，我得到所有请求的属性，但在S.DS中。P，我没有GUID，或者HomePhone…

其余部分只适用于一个用户。

任何想法?

public static List<AllAdStudentsCV> GetUsersDistinguishedName( string domain, string distinguishedName )
        {
            try
            {
                NetworkCredential credentials               = new NetworkCredential( ConfigurationManager.AppSettings[ "AD_User" ], ConfigurationManager.AppSettings[ "AD_Pass" ] ); 
                LdapDirectoryIdentifier directoryIdentifier = new LdapDirectoryIdentifier( domain+":389" ); 
                using ( LdapConnection connection           = new LdapConnection( directoryIdentifier, credentials ) )
                {
                    SearchRequest searchRequest = new SearchRequest( );
                    searchRequest.DistinguishedName = distinguishedName;
                    searchRequest.Filter = "(&(objectCategory=person)(objectClass=user)(sn=Afcan))";//"(&(objectClass=user))";
                    searchRequest.Scope = SearchScope.Subtree;
                    searchRequest.Attributes.Add("name");
                    searchRequest.Attributes.Add("sAMAccountName");
                    searchRequest.Attributes.Add("uid");
                    searchRequest.Attributes.Add("telexNumber"); // studId
                    searchRequest.Attributes.Add("HomePhone"); //ctrId
                    searchRequest.SizeLimit = Int32.MaxValue;
                    searchRequest.TimeLimit = new TimeSpan(0, 0, 45, 0);// 45 min - EWB
                    SearchResponse searchResponse = connection.SendRequest(searchRequest) as SearchResponse;
                    if (searchResponse == null) return null;
                    List<AllAdStudentsCV> users = new List<AllAdStudentsCV>();
                    foreach (SearchResultEntry entry in searchResponse.Entries)
                    {
                        AllAdStudentsCV user = new AllAdStudentsCV();
                        user.Active = "Y";
                        user.CenterName = "";
                        user.StudId = GetstringAttributeValue(entry.Attributes, "telexNumber");
                        user.CtrId = GetstringAttributeValue(entry.Attributes, "HomePhone");
                        user.Guid = GetstringAttributeValue(entry.Attributes, "uid");
                        user.Username = GetstringAttributeValue(entry.Attributes, "sAMAccountName");
                        users.Add(user);
                    }
                    return users;
                }
            }
            catch (Exception ex)
            {
                throw;
            }
        }

另外，如果我想在AD中获取每个用户，所以我可以与我的SQL数据库同步数据，我该如何做到这一点，我一直在获得最大尺寸超过，错误。我将大小设置为maxxint32…是否有"忽略大小"选项?

谢谢,
