Authz File Administration Plugin
This plugin registers a module into the WebAdmin to allow the configuration of the svnauthz file from the web interface. It uses the AccountManager plugin to present the list of users.
This plugin requires Trac 0.12 or later, and uses the repo names reported in the Version Control | Repositories admin panel to determine which repos to display when the show_all_repos option is set to false (default).

General instructions on installing Trac plugins can be found on the TracPlugins page.
It uses the authz_file setting from the [trac] section of your trac.ini file to find the svnauthz file.
There is a read_only_display option that, when enabled, prevents any changes to the authz_file being made. There is also a show_all_repos option to show all repo paths contained in the authz_file.
