Can anybody tell me what a login server is ? From what i know - it is used to login to a private network from outside the network. Is that the only functionality of a login server ?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
Where I work, "login server" simply means a system whose primary purpose is to provide interactive (i.e., shell via ssh) access to our user community. It can also act as a gateway into our network environment.
In other environments, "login server" may refer to something completely different -- for example, some web authentication products refer to the authentication server as the "login server" (http://www.pubcookie.org/docs/install-login.html). This may actually be the more common use; a search on Google for "login server" leads to lots of web-centric information.
