I'm currently implementing single sign on across Plone sites but have run into a bit of an issue with the CookieAuthHelper.
Unauthorized accesses are redirected to its login_path attribute even when a user is already logged in. Plone works around this with a require_login script that traverses to insufficient_privileges (rather than login_form) when the user is not anonymous. http://dev.plone.org/plone/browser/Plone/trunk/Products/CMFPlone/skins/plone...
I'd like to avoid having two redirects (one to require_login and then one to the remote login page).
One option (as suggested in require_login.py) would be to have CookieAuthHelper traverse rather than redirect to the login_path so that sites could override the behaviour, though they would then presumably need to duplicate the functionality currently in CookieAuthHelper.unauthorized (which I must admit to only barely understanding...) http://zope3.pov.lt/trac/browser/Products.PluggableAuthService/trunk/Product...
Instead, it would seem to make sense to move this functionality login / insufficient privileges functionality into the CookieAuthHelp itself. I could add an insufficient_privs_path and redirect there instead of login_path when a user is already authorized.
Yet another option would be to let logged in unauthorized to percolate up and implement that page with an error view.
Any opinions? I'm leaning towards adding an insufficient_privs_path as it seems simplest and least invasive. (When not set it would just use login_path as normal).
