What would be the risk(s) to use specific ldap groups for that
purpose? (managing all access in a similar way may be better, no?)

LDAP groups should as well map team membership. So marketing team guys
would belong to such a marketingTeam group then.

We probably won't nail this one in one shot :-)

As for web, we would need three roles:
 - web-apprentice
 - web (commits to web repos and pushes to tests servers)
 - webmaster (pushes to prod servers)

We need groups as well for (not exclusive):
 - being a team representative (that is, in the Council)
 - being an association member (eligible and elector)
 - being a board member
 - being the chair(wo)man

Are group belonging/ownership a "one-time" record or does it get
archived? (to access a history of past membership). Or should such a
history be built separately?
