Re: communicating via telnet with windows 2012 server

Tim,

    You may want to talk to your admins about this.  Since this is a 
Windows server, I'm making the assumption that your company is running 
on Active Directory.  If they have configured a domain controller as a 
global catalog, you could hit that server via LDAPS (TCP/636) and change 
the password via LDAP.  We have a CL program that calls a PHP program 
(via Pase).  On the IBM i change password, we use an exit hook to call 
the CL.  The CL program passes the username and password to the PHP 
program.  Then the PHP program communicates with LDAPS to change the 
password on Active Directory.  Yes, it's patch work and a bit crude, but 
it has served us well.  The PHP program also email our IT staff if the 
password change is a success or failure.  I would be willing to share 
the CL and PHP code.  We used PHP because there were already libraries 
available to could communicate with LDAP, without writing our own 
communications handler.

    We struggled with the same issue you guys are facing.  I was even 
able to change the password via FTP on the Windows server. The problem 
with both FTP and Telnet is the communications is 
unencrypted/unsecured.  With PHP via LDAPS, the communications was 
secure.  Plus, it was a service that was already running on the Windows 
Server without having to enable additional services such as telnet and 
IIS/FTP.

    I know this wasn't what you requested (via telnet), but thought I'd 
throw it out.
