Doesn't have to be. On our Gentoo Linux servers, we use LDAP; Mac OS
X computers use NetInfo. /etc/passwd will not contain anything useful
with regard to names of actual users on such systems.

That doesn't have to be either. HTTP[S] can use any authentication
mechanism offered by Apache. It's not limited to .htpasswd files. We
use LDAP for this too.

This points to the heart of the problem: Subversion is not an
authentication system, but it can use several different
authentication systems. So you need to write something that talks to
the authentication system you use for Subversion. Or, if you want a
general solution, you need to write something that talks to all
authentication systems that could be used with Subversion (that's
probably a long list).
