Jay,
The STA is NOT a Certficate Authority and DOES NOT give out PKI
Certificates, what it does is generate tickets so that users never know the
actual IP Address of the MetaFrame Servers, and no Username/Password
information travels through the insecure network or the Internet (although,
you COULD use Nfuse ticketing which would protect the Username/Password but
not the MF Internal IP Address).
The STA is MANDATORY and is no 3rd party can provide a substitute if you use
Citrix Secure Gateway in normal mode (there is a relay mode that does not
need the STA, but should only be used in specific scenarios).
Bottom line, your Engineering team SHOULD read the CSG Administrator's
Guide. Or even better, help out your friends and hire a Citrix Consultant in
your area. :-)
Cheers,
Carlos Sanabria, CCA, MCSA
IT Consultant

Sorry if I am mistaken but I do not do any of the security and I depend on
others for this environment. I was told by a person that is engineering our
Secure Gateway that for the STA server that should be used is a 3rd party
secure server external to the company and that external company would act as
our Certificate Authority server. From what they explained to me that this
CA server would act as my Secure Ticket Authority.
IF they are giving me an incorrect engineered environment, I need to
understand what that may be so I can question their solution. That is the
basis of my question. I have my doubts that this is the right approach.
From what you just told me it sounds like their engineered method will not
work.
Is this correct?
Thanks again.
Jay

Jay, I'm not sure I understand. Your STA is a machine, usually internal,
that handles the authentication steps. It has the STA piece of Secure
Gateway installed. If what you are asking about is the secure
certificate(s) needed, then that is a whole different ballgame. We generate
our own, but it does cause problems. They are no more or less secure than
any other 128bit certificate, but you have to have your root added as a
Trusted Root CA on every client machine. In some cases that is a real pain.
Had I the chance to do it over again, I might choose a different route and
just cough up the cash.
