+Long Term Clipper Adapter
+=========================
+
+We provide an easy-to-use SocialAccountAdapter to handle the fact that Clipper Accounts are not eternal, and that there is no guarantee that the clipper usernames won't be reused later.
+
+This adapter also handles getting basic information about the user from SPI's LDAP.
+
+Configuration
+  Set ``SOCIALACCOUNT_ADAPTER='allauth_ens.adapter.LongTermClipperAccountAdapter'`` in `settings.py`
+
+Auto-signup
+  Populated data
+    - username: ``<clipper>@<entrance year>``
+    - email: from LDAP's `mailRoutingAddress` field, or ``<clipper>@clipper.ens.fr``
+    - first_name, last_name from LDAP's `cn` field
+    - extra_data in SociallAccount instance, containing these field, plus `anne` and `promotion` from LDAP's `homeDirectory` field (available only on first connection)
+      
+Account deprecation
+  At the beginning of each year (i.e. early November), to prevent clipper username conflicts, you should run ``$ python manage.py deprecate_clippers``. Every association clipper username <-> user will then be set on hold, and at the first subsequent connection, a verification of the account will be made (using LDAP), so that a known user keeps his account, but a newcomer won't inherit an archicube's.
+
+Customize
+  You can customize the SocialAccountAdapter by inheriting ``allauth_ens.adapter.LongTermClipperAccountAdapter``. You might want to modify ``get_username(clipper, data)`` to change the default username format. This function is used to disambiguate in the account deprecation process.
