Share Trac cookies between projects in the same environment
Description
SharedCookieAuthPlugin allows cookies to be shared between Trac instances in the same environment (i.e. directory). The plugin monkey-patches trac.web.auth.LoginModule so that cookies get set at / instead of req.base_path (See following note). The incoming request is then passed by the authenticate method of the IAuthenticator interface to projects that peer the project of interest to see if the user is authenticated there. This enables single-sign on for Trac projects in the same directory.
Note: As per request in T#8486 a new configuration option, has been introduced to Trac with changeset T:[9226], that accomplished this:
[trac] auth_cookie_path = /var/www/trac
So this has been made a part of Trac, and a simplified plugin version (not yet available) should work for Trac version >= 0.12 without that monkey-patching.
