I wrote a Symfony 1.4 (Doctrine) Website consisting of 2 frontends and 2 backends. So all is neatly packed in 2 SF-Projects - anyways all the apps use the same (MySQL-)database. This is not a problem at all until it comes to the point of logging in different users.
Backend 1 can only be accessed from the intra-net, so here's just a few users (admins) to manage. Backend 2 can be accessed from the extra-net and should manage the frontend-users, too.
Basically I want to split this two Projects in 2 different sets of user-tables - but within one Database.
I use the sfDoctrineGuardPlugin to secure the first app and I'm not sure how to manage securing the second one without interfering the 1st.
