Just wondering what the most popular approach is for authentication and
authorisation in a rails application that is deployed and fronted by
apache? Also when there are say a couple of rails apps being hosted.
 Options would seem to include:
- Do it within rails/your app? Use of a “before_filter” per the Rails
- Use of Apache to authenticator & define users? (I’m just assuming
this is an option).
 Also if you wanted to have users use multiple deployed rails apps on
the same hosted site what mechanism is the most popular to leverage this
(i.e. a standalone rails user management web app, use of apache etc?)
 I assume this would need to be implemented in the ruby app but
a) do it separately in each app (i.e. re-implement each time) OR
b) have a common user/role table that each deployed rails app hooks into
- in this case whats the best mechanism to extract/abstract the code out
of each rails application?
