There exists a special version of VisualSVN thats packed with trac. While this install isn't quite as straight-forward as the standard package - whoever has installed python on a production server knows what I'm talking about - once setup it works remarkably well. Except for true single-sign-on.
To address this issue I figured that VisualSVN is just comprised of apache plus some svn modules. So it should be easy to hack in support to auth against an Active Directory. There are quite a few options when it comes to this. I found only one working stable: mod_auth_sspi.
To get the correct modules and dependancies I installed a stand-alone apache (the exact version that ships with VisualSVN + Trac), and went from there. I blatantly copied any missing deps into the visualsvn/bin folder.
Here's my httpd.conf:
#
# This is configuration file for Apache HTTP server which is
# part of VisualSVN Server.
#
# DO NOT EDIT THIS FILE IT WILL BE REGENERATED AUTOMATICALLY BY VISUALSVN SERVER
#
# Contact with VisualSVN Ltd. (support@visualsvn.com) if you have suggestions and
# improvements.

And the httpd-custom.conf which includes the trac configuration:

I decided to run a https server. To avoid nasty Internet Explorer warnings about certificates and whatnot, you can either disable the checks for certificates, or create a proper certificate if you are lucky and you've got a CA server in your domain. Here's how to create a proper cert using openSSL and a windows CA. Copy them onto your svn server and that's it.
