"""
The database models for the 'users' app of re2o.
The goal is to keep the main actions here, i.e. the 'clean' and 'save'
function are higly reposnsible for the changes, checking the coherence of the
data and the good behaviour in general for not breaking the database.
For further details on each of those models, see the documentation details for
each.
Here are defined the following django models :
* Users : Adherent and Club (which inherit from Base User Abstract of django).
* Whitelists
* Bans
* Schools (teaching structures)
* Rights (Groups and ListRight)
* ServiceUser (for ldap connexions)
Also define django-ldapdb models :
* LdapUser
* LdapGroup
* LdapServiceUser
These objects are sync from django regular models as auxiliary models from
sql data into ldap.
