Redmine

Hey,

I have read multiple guides on how to do a integration between the two systems, like

https://paulsalcido.com/2012/06/18/integrating-redmine-and-gitolite/
http://blog.sobex-software.de/?p=278

but not a single one has made a statement about if we can still use the fine-grained permissions from Gitolite, the guides only speak about being able to use Redmines predefined groups.
A little insight would be appreciated :)
