in master branch grack_auth.rb doesn't exist
Created by: davispuh
Why config/initializers/grack_auth.rb doesn't exist in master branch but does in stable?
for me simple git checkout stable config/initializers/grack_auth.rb worked fine
another thing that I'm using nginx with passenger and had to change @env['REQUEST_PATH'] to @env['REQUEST_URI'] (at line 16) because there wasn't such REQUEST_PATH
