``django-ldapdb`` is an LDAP database backend for Django, allowing to manipulate
LDAP entries through Django models.
It supports most of the same APIs as a Django model:
* ``MyModel.objects.create()``
* ``MyModel.objects.filter(x=1, y__contains=2)``
* Full admin support and browsing
``django-ldapdb`` supports Django versions 1.11 / 2.0 / 2.1, and Python 2.7 / 3.4 / 3.5 / 3.6 / 3.7,
as far as the Django and Python versions are compatible.
Installing django-ldapdb
------------------------
Linux
~~~~~
Use pip: ``pip install django-ldapdb``
You might also need the usual ``LDAP`` packages from your distribution, usually named ``openldap`` or ``ldap-utils``.
Windows
~~~~~~~
``django-ldapdb`` depends on the `python-ldap <https://pypi.python.org/pypi/python-ldap>` project.
Either follow `its Windows installation guide <https://www.python-ldap.org/en/latest/installing.html>`_,
or install a pre-built version from https://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap
(choose the ``.whl`` file matching your Python/Windows combination, and install it with ``pip install python-ldap-3...whl``).
and then you can also install ``django-ldapdb`` with
``pip install django-ldapdb``
Using django-ldapdb
-------------------
Add the following to your ``settings.py``:
.. code-block:: python
DATABASES = {
'ldap': {
'ENGINE': 'ldapdb.backends.ldap',
'NAME': 'ldap://ldap.nodomain.org/',
'USER': 'cn=admin,dc=nodomain,dc=org',
'PASSWORD': 'some_secret_password',
},
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
},
}
DATABASE_ROUTERS = ['ldapdb.router.Router']
If you want to access posixGroup entries in your application, you can add
something like this to your ``models.py``:
.. code-block:: python
from ldapdb.models.fields import CharField, IntegerField, ListField
import ldapdb.models
class LdapGroup(ldapdb.models.Model):
"""
Class for representing an LDAP group entry.
"""
# LDAP meta-data
base_dn = "ou=groups,dc=nodomain,dc=org"
object_classes = ['posixGroup']
# posixGroup attributes
gid = IntegerField(db_column='gidNumber', unique=True)
name = CharField(db_column='cn', max_length=200, primary_key=True)
members = ListField(db_column='memberUid')
def __str__(self):
return self.name
def __unicode__(self):
return self.name
and add this to your ``admin.py``:
.. code-block:: python
from django.contrib import admin
from . import models
class LDAPGroupAdmin(admin.ModelAdmin):
exclude = ['dn', 'objectClass']
list_display = ['gid', 'name']
admin.site.register(models.LDAPGroup, LDAPGroupAdmin)
**Important note:**
You **must** declare an attribute to be used as the primary key.
This attribute will play a special role, as it will be used to build
the Relative Distinguished Name of the entry.
For instance in the example above, a group whose cn is ``foo``
will have the DN ``cn=foo,ou=groups,dc=nodomain,dc=org``.
Supported fields
----------------
djanglo-ldapdb provides the following fields, all imported from ``ldapdb.models.fields``:
Similar to Django:
* ``IntegerField``
* ``FloatField``
* ``CharField``
* ``ImageField``
* ``DateTimeField``
Specific to a LDAP server:
* ``ListField`` (holds a list of text values)
* ``TimestampField`` (Stores a datetime as a posix timestamp, typically for posixAccount)
Legacy:
* ``DateField`` (Stores a date in an arbitrary format. A LDAP server has no notion of ``Date``).
Tuning django-ldapdb
--------------------
It is possible to adjust django-ldapdb's behavior by defining a few parameters in the ``DATABASE`` section:
``PAGE_SIZE`` (default: ``1000``)
Define the maximum size of a results page to be returned by the server
``QUERY_TIMEOUT`` (default: no limit)
Define the maximum time in seconds we'll wait to get a reply from the server (on a per-query basis).
.. note:: This setting applies on individual requests; if a high-level operation requires many
queries (for instance a paginated search yielding thousands of entries),
the timeout will be used on each individual request;
the overall processing time might be much higher.
