Re: FSFS repo on a network share

Thanks guys.

I was thinking about just using file:// since it would greatly simplify
everything, but worried about the consequences.

Currently, the setup I've implemented is clumsy. Because of the
confidentiality of work between researchers, they currently run a local
Apache service (logged in as them through the network to get the right
privileges to access the repo). The service authenticates against the
Windows authentication (Active Directory?), which svnserve can't do
(easily). So access to repos are by HTTP requests to the local workstation.

It works, but it's clumsy because:

   - there's a bunch of local Apache services running, when it should really
   be centralized at the server where the repos are stored,
   - user passwords are regularly changed and the researchers have to
   re-input their passwords for the local Apache service to continue to log in
   as them (to get the correct privileges to access the repo), and
   - the local workstation where the service is run has to be on (and logged
   in?) in order for the manager (the only other person accessing the repos) to
   access the remote repo

Am I circumventing the safety measures by having the SVN server retrieve the
repo over the network?

I don't have full access to the server that stores all these repos as I'm a
researcher myself. The IT folks don't want to maintain a collection of
research repos, so I'm looking for a work-around that is not as clumsy. -_-
