/**************************************************************
SocketOnConnected(SOCKET s, const char *lpszName)
If the security is enabled then perform te SSL neogotiation
otherwise just return a success and let the plain text FTP handles
the comunication
To let the server know that we are looking for SSL or TLS we need to
send the following command
FEAT
The Feature negotiation mechanism for the File Transfer Protocol
To ask the server for SSL or TLS negotiation
we will send the AUTH command.
A parameter for the AUTH command to indicate that TLS is
required. It is recommended that 'TLS', 'TLS-C', 'SSL' and 'TLS-P'
are acceptable, and mean the following :-
'TLS' or 'TLS-C' - the TLS protocol or the SSL protocol will be
negotiated on the control connection. The default protection
setting for the Data connection is 'Clear'.
'SSL' or 'TLS-P' - the TLS protocol or the SSL protocol will be
negotiated on the control connection. The default protection
setting for the Data connection is 'Private'. This is primarily
for backward compatibility.
Notice that we will first send a TLS P to select The highest implementation.
the server might response with the response
503 unknown security mechanism
if this happened we will issue an Auth SSL command.
Param:
SOCKET s - The newly created socket
lpszName - apointer to the host name we are attempting to connect to
Return:
UTE_NO_RESPONSE - Server did not response to our command
UTE_CONNECT_FAIL_NO_SSL_SUPPORT - Server does not support SSL.
UTE_CONNECT_FAILED - The connection have failed
security errors - This function may fail with other error

Added string length limitations
as enforced by RFC 821
There are several objects that have required minimum maximum
sizes. That is, every implementation must be able to receive
objects of at least these sizes, but must not send objects
larger than these sizes.
****************************************************

****************************************************
user
The maximum total length of a user name is 64 characters.
domain
The maximum total length of a domain name or number is 64
characters.
path
The maximum total length of a reverse-path or
forward-path is 256 characters (including the punctuation
and element separators).
command line
The maximum total length of a command line including the
command word and the <CRLF> is 512 characters.
reply line
The maximum total length of a reply line including the

recipients buffer
The maximum total number of recipients that must be
