Wrong sitename on login page
The template uses {{ sitename }}
on the top left-hand corner of the navbar to display "Re2o" or whatever the configuration specifies. I think, this variable comes from a context
dictionary available at template rendering time. On login page, it seems django.contrib.auth.login
generates the page but modify this context because {{ sitename }}
outputs the full domain name ("Re2o.rez-rennes.fr" for instance) instead.
This behavior needs to be checked, see if that's really django.contrib.auth.login
's fault and fix it.
