ident fails on win2k host...

i have set up my win2k box with postgres with 7.1.3 cygwin pre-built. i have
opened a port in my firewall to allow postgres requests to go through. a
remote user is attempting to hit the box but is getting an ident error. in
the admin.pdf doc i find the following about ident authentication...

   "The ident server on the client host is asked
   for the identity of the connecting user.
   Postgres then verifies whether the so identified
   operating system user is allowed to connect as
   the database user that is requested. This is only
   available for TCP/IP connections. The
   authentication option following the ident keyword
   specifies the name of an ident map that specifies
   which operating system users equate with which
   database users. See below for details."

does ident authentication work under win2k?

if so, does this mean that i need to add my remote user as a user on my
win2k machine?

if so, what rights do they need to have? and do i need to configure my
firewall to allow a different port to be opened up?

if i cannot use ident based authentication under cygwin, how do i allow
remote users who are using the win32 ODBC driver to connect to the database?
should i switch to kerberos? if so, which version?

he'p me! he'p me! i been hyp-mo-tized!

many thanks,
