No webserver, gateway... question that every forum is full of. Here is a
practical question.

I have quite experience in setting Microsoft servers but all of that for
people who decided to pay for them. Besides I don't want to spend that money
for setting that stuff for myself. Instead I'd like to have a Linux based
environment (mixed one of course due to the windows licenses I already own).
So far I succeeded in setting server to serve as intranet webserver but now
I need to get authentification and authorisation role in the active
directory way (or similar). Actualy I'd like my workstations to be added in
some kind of local domain (I've noticed that linux terminology vary from
microsoft one so I may do some mistakes) so users can perform local loggon
that is checked on the linux server - and in extention depending on the
success of credential check they can or can not use local machine
(workstation). There's no need to say that this makes possible for users to
log onto different machines in that "domain" and have adequate rights (it's
up to domain group he/she belongs to) to use files, printers..., and all of
that administrated centraly.

And here is the question. What subjects should I focuse to accomplish things
above. However I need the best solution that Linux world offers. It's very
difficult to filter out all the howtos, tutorials regarding linux.

Thanx, Edi
