I noticed that Subversion treats SSH-tunneled connections as
"authenticated" and sets the user name in the logs correctly. If I
connect to the repository via local- or svnserve-access, the connection
is treated as "unauthenticated" by default.

I inferred, that the tunneled access gets a special treatment. I just
wondered how this is done and if it can be done similarly in non-SSH
connections.

When there is no need for the strong encryption SSH provides, why then
burden the server with the extra load?

Since the repository is used only in the intranet (or from outside
through VPN), the Apache solution is not really interesting for me.

Thanks,
