.. setting:: AUTH_LDAP_ALWAYS_UPDATE_USER
Default: True
If True
, the fields of a :class:`~django.contrib.auth.models.User` object
will be updated with the latest values from the LDAP directory every time the
user logs in. Otherwise the :class:`~django.contrib.auth.models.User` object
will only be populated when it is automatically created.
.. setting:: AUTH_LDAP_AUTHORIZE_ALL_USERS
Default: False
If True
, :class:`~django_auth_ldap.backend.LDAPBackend` will be able furnish
permissions for any Django user, regardless of which backend authenticated it.
.. setting:: AUTH_LDAP_BIND_AS_AUTHENTICATING_USER
Default: False
If True
, authentication will leave the LDAP connection bound as the
authenticating user, rather than forcing it to re-bind with the default
credentials after authentication succeeds. This may be desirable if you do not
have global credentials that are able to access the user's attributes.
django-auth-ldap never stores the user's password, so this only applies to
requests where the user is authenticated. Thus, the downside to this setting is
that LDAP results may vary based on whether the user was authenticated earlier
in the Django view, which could be surprising to code not directly concerned
with authentication.
.. setting:: AUTH_LDAP_BIND_DN
Default: ''
(Empty string)
The distinguished name to use when binding to the LDAP server (with
:setting:`AUTH_LDAP_BIND_PASSWORD`). Use the empty string (the default) for an
anonymous bind. To authenticate a user, we will bind with that user's DN and
password, but for all other LDAP operations, we will be bound as the DN in this
setting. For example, if :setting:`AUTH_LDAP_USER_DN_TEMPLATE` is not set, we'll
use this to search for the user. If :setting:`AUTH_LDAP_FIND_GROUP_PERMS` is
True
, we'll also use it to determine group membership.
.. setting:: AUTH_LDAP_BIND_PASSWORD
Default: ''
(Empty string)
The password to use with :setting:`AUTH_LDAP_BIND_DN`.
.. setting:: AUTH_LDAP_CACHE_TIMEOUT
Default: 0
The value determines the amount of time, in seconds, a user's group memberships
and distinguished name are cached. The value 0
, the default, disables
caching entirely.
.. versionchanged:: 1.6.0 Previously caching was controlled by the settings `AUTH_LDAP_CACHE_GROUPS` and `AUTH_LDAP_GROUP_CACHE_TIMEOUT`. If `AUTH_LDAP_CACHE_GROUPS` is set, the `AUTH_LDAP_CACHE_TIMEOUT` value is derievd from these deprecated settings.
.. setting:: AUTH_LDAP_CONNECTION_OPTIONS
Default: {}
A dictionary of options to pass to each connection to the LDAP server via :meth:`LDAPObject.set_option() <ldap.LDAPObject.set_option>`. Keys are :ref:`ldap.OPT_* <ldap-options>` constants.
.. setting:: AUTH_LDAP_DENY_GROUP
Default: None
The distinguished name of a group; authentication will fail for any user that belongs to this group.
.. setting:: AUTH_LDAP_FIND_GROUP_PERMS
Default: False
If True
, :class:`~django_auth_ldap.backend.LDAPBackend` will furnish group
permissions based on the LDAP groups the authenticated user belongs to.
:setting:`AUTH_LDAP_GROUP_SEARCH` and :setting:`AUTH_LDAP_GROUP_TYPE` must also be
set.
.. setting:: AUTH_LDAP_GLOBAL_OPTIONS
Default: {}
A dictionary of options to pass to :func:`ldap.set_option`. Keys are :ref:`ldap.OPT_* <ldap-options>` constants.
Note
Due to its global nature, this setting ignores the :doc:`settings prefix <multiconfig>`. Regardless of how many backends are installed, this setting is referenced once by its default name at the time we load the ldap module.
.. setting:: AUTH_LDAP_GROUP_SEARCH
Default: None
An :class:`~django_auth_ldap.config.LDAPSearch` object that finds all LDAP groups that users might belong to. If your configuration makes any references to LDAP groups, this and :setting:`AUTH_LDAP_GROUP_TYPE` must be set.
.. setting:: AUTH_LDAP_GROUP_TYPE
Default: None
An :class:`~django_auth_ldap.config.LDAPGroupType` instance describing the type of group returned by :setting:`AUTH_LDAP_GROUP_SEARCH`.
.. setting:: AUTH_LDAP_MIRROR_GROUPS
Default: None
If True
, :class:`~django_auth_ldap.backend.LDAPBackend` will mirror a user's
LDAP group membership in the Django database. Any time a user authenticates, we
will create all of their LDAP groups as Django groups and update their Django
group membership to exactly match their LDAP group membership. If the LDAP
server has nested groups, the Django database will end up with a flattened
representation.
This can also be a list or other collection of group names, in which case we'll only mirror those groups and leave the rest alone. This is ignored if :setting:`AUTH_LDAP_MIRROR_GROUPS_EXCEPT` is set.
.. setting:: AUTH_LDAP_MIRROR_GROUPS_EXCEPT
Default: None
If this is not None
, it must be a list or other collection of group names.
This will enable group mirroring, except that we'll never change the membership
of the indicated groups. :setting:`AUTH_LDAP_MIRROR_GROUPS` is ignored in this
case.
.. setting:: AUTH_LDAP_PERMIT_EMPTY_PASSWORD
Default: False
If False
(the default), authentication with an empty password will fail
immediately, without any LDAP communication. This is a secure default, as some
LDAP servers are configured to allow binds to succeed with no password, perhaps
at a reduced level of access. If you need to make use of this LDAP feature, you
can change this setting to True
.
.. setting:: AUTH_LDAP_REQUIRE_GROUP
Default: None
The distinguished name of a group; authentication will fail for any user that does not belong to this group. This can also be an :class:`~django_auth_ldap.config.LDAPGroupQuery` instance.
.. setting:: AUTH_LDAP_NO_NEW_USERS
Default: False
Prevent the creation of new users during authentication. Any users not already in the Django user database will not be able to login.
.. setting:: AUTH_LDAP_SERVER_URI
Default: 'ldap://localhost'
The URI of the LDAP server. This can be any URI that is supported by your
underlying LDAP libraries. Can also be a callable that returns the URI. The
callable is passed a single positional argument: request
.
.. versionchanged:: 1.7.0 When ``AUTH_LDAP_SERVER_URI`` is set to a callable, it is now passed a positional ``request`` argument. Support for no arguments will continue for backwards compatibility but will be removed in a future version.
.. setting:: AUTH_LDAP_START_TLS
Default: False
If True
, each connection to the LDAP server will call
:meth:`~ldap.LDAPObject.start_tls_s` to enable TLS encryption over the standard
LDAP port. There are a number of configuration options that can be given to
:setting:`AUTH_LDAP_GLOBAL_OPTIONS` that affect the TLS connection. For example,
:data:`ldap.OPT_X_TLS_REQUIRE_CERT` can be set to :data:`ldap.OPT_X_TLS_NEVER`
to disable certificate verification, perhaps to allow self-signed certificates.
.. setting:: AUTH_LDAP_USER_QUERY_FIELD
Default: None
The field on the user model used to query the authenticating user in the
database. If unset, uses the value of USERNAME_FIELD
of the model class.
When set, the value used to query is obtained through the
:setting:`AUTH_LDAP_USER_ATTR_MAP`. For example, setting :setting:`AUTH_LDAP_USER_QUERY_FIELD`
to username
and adding "username": "sAMAccountName",
to :setting:`AUTH_LDAP_USER_ATTR_MAP`
will cause django to query local database using username
column and LDAP using
sAMAccountName
attribute.
.. setting:: AUTH_LDAP_USER_ATTRLIST
Default: None
A list of attribute names to load for the authenticated user. Normally, you can ignore this and the LDAP server will send back all of the attributes of the directory entry. One reason you might need to override this is to get operational attributes, which are not normally included:
AUTH_LDAP_USER_ATTRLIST = ["*", "+"]
.. setting:: AUTH_LDAP_USER_ATTR_MAP
Default: {}
A mapping from :class:`~django.contrib.auth.models.User` field names to LDAP attribute names. A users's :class:`~django.contrib.auth.models.User` object will be populated from his LDAP attributes at login.
.. setting:: AUTH_LDAP_USER_DN_TEMPLATE
Default: None
A string template that describes any user's distinguished name based on the
username. This must contain the placeholder %(user)s
.
.. setting:: AUTH_LDAP_USER_FLAGS_BY_GROUP
Default: {}
A mapping from boolean :class:`~django.contrib.auth.models.User` field names to
distinguished names of LDAP groups. The corresponding field is set to True
or False
according to whether the user is a member of the group.
Values may be strings for simple group membership tests or :class:`~django_auth_ldap.config.LDAPGroupQuery` instances for more complex cases.
.. setting:: AUTH_LDAP_USER_SEARCH
Default: None
An :class:`~django_auth_ldap.config.LDAPSearch` object that will locate a user
in the directory. The filter parameter should contain the placeholder
%(user)s
for the username. It must return exactly one result for
authentication to succeed.
.. module:: django_auth_ldap
.. data:: version The library's current version number as a 3-tuple.
.. data:: version_string The library's current version number as a string.
.. module:: django_auth_ldap.config
.. method:: __init__(base_dn, scope, filterstr='(objectClass=*)') :param str base_dn: The distinguished name of the search base. :param int scope: One of ``ldap.SCOPE_*``. :param str filterstr: An optional filter string (e.g. '(objectClass=person)'). In order to be valid, ``filterstr`` must be enclosed in parentheses.
.. versionadded:: 1.1
.. method:: __init__(\*searches) :param searches: Zero or more LDAPSearch objects. The result of the overall search is the union (by DN) of the results of the underlying searches. The precedence of the underlying results and the ordering of the final results are both undefined. :type searches: :class:`LDAPSearch`
The base class for objects that will determine group membership for various LDAP grouping mechanisms. Implementations are provided for common group types or you can write your own. See the source code for subclassing notes.
.. method:: __init__(name_attr='cn') By default, LDAP groups will be mapped to Django groups by taking the first value of the cn attribute. You can specify a different attribute with ``name_attr``.
A concrete subclass of :class:`~django_auth_ldap.config.LDAPGroupType` that
handles the posixGroup
object class. This checks for both primary group
and group membership.
.. method:: __init__(name_attr='cn')
A concrete subclass of :class:`~django_auth_ldap.config.LDAPGroupType` that handles grouping mechanisms wherein the group object contains a list of its member DNs.
.. method:: __init__(member_attr, name_attr='cn') :param str member_attr: The attribute on the group object that contains a list of member DNs. 'member' and 'uniqueMember' are common examples.
Similar to :class:`~django_auth_ldap.config.MemberDNGroupType`, except this allows groups to contain other groups as members. Group hierarchies will be traversed to determine membership.
.. method:: __init__(member_attr, name_attr='cn') As above.
A concrete subclass of :class:`~django_auth_ldap.config.MemberDNGroupType`
that handles the groupOfNames
object class. Equivalent to
MemberDNGroupType('member')
.
.. method:: __init__(name_attr='cn')
A concrete subclass of
:class:`~django_auth_ldap.config.NestedMemberDNGroupType` that handles the
groupOfNames
object class. Equivalent to
NestedMemberDNGroupType('member')
.
.. method:: __init__(name_attr='cn')
A concrete subclass of :class:`~django_auth_ldap.config.MemberDNGroupType`
that handles the groupOfUniqueNames
object class. Equivalent to
MemberDNGroupType('uniqueMember')
.
.. method:: __init__(name_attr='cn')
A concrete subclass of
:class:`~django_auth_ldap.config.NestedMemberDNGroupType` that handles the
groupOfUniqueNames
object class. Equivalent to
NestedMemberDNGroupType('uniqueMember')
.
.. method:: __init__(name_attr='cn')
A concrete subclass of :class:`~django_auth_ldap.config.MemberDNGroupType`
that handles Active Directory groups. Equivalent to
MemberDNGroupType('member')
.
.. method:: __init__(name_attr='cn')
A concrete subclass of
:class:`~django_auth_ldap.config.NestedMemberDNGroupType` that handles
Active Directory groups. Equivalent to
NestedMemberDNGroupType('member')
.
.. method:: __init__(name_attr='cn')
A concrete subclass of :class:`~django_auth_ldap.config.MemberDNGroupType`
that handles the organizationalRole
object class. Equivalent to
MemberDNGroupType('roleOccupant')
.
.. method:: __init__(name_attr='cn')
A concrete subclass of
:class:`~django_auth_ldap.config.NestedMemberDNGroupType` that handles the
organizationalRole
object class. Equivalent to
NestedMemberDNGroupType('roleOccupant')
.
.. method:: __init__(name_attr='cn')
Represents a compound query for group membership.
This can be used to construct an arbitrarily complex group membership query
with AND, OR, and NOT logical operators. Construct primitive queries with a
group DN as the only argument. These queries can then be combined with the
&
, |
, and ~
operators.
This is used by certain settings, including :setting:`AUTH_LDAP_REQUIRE_GROUP` and :setting:`AUTH_LDAP_USER_FLAGS_BY_GROUP`. An example is shown in :ref:`limiting-access`.
.. method:: __init__(group_dn) :param str group_dn: The distinguished name of a group to test for membership.
.. module:: django_auth_ldap.backend
.. data:: populate_user This is a Django signal that is sent when clients should perform additional customization of a :class:`~django.contrib.auth.models.User` object. It is sent after a user has been authenticated and the backend has finished populating it, and just before it is saved. The client may take this opportunity to populate additional model fields, perhaps based on ``ldap_user.attrs``. This signal has two keyword arguments: ``user`` is the :class:`~django.contrib.auth.models.User` object and ``ldap_user`` is the same as ``user.ldap_user``. The sender is the :class:`~django_auth_ldap.backend.LDAPBackend` class.
.. data:: ldap_error This is a Django signal that is sent when we receive an :exc:`ldap.LDAPError` exception. The signal has three keyword arguments: - ``context``: one of ``'authenticate'``, ``'get_group_permissions'``, or ``'populate_user'``, indicating which API was being called when the exception was caught. - ``user``: the Django user being processed (if available). - ``exception``: the :exc:`~ldap.LDAPError` object itself. The sender is the :class:`~django_auth_ldap.backend.LDAPBackend` class (or subclass).
:class:`~django_auth_ldap.backend.LDAPBackend` has one method that may be called directly and several that may be overridden in subclasses.
.. data:: settings_prefix A prefix for all of our Django settings. By default, this is ``'AUTH_LDAP_'``, but subclasses can override this. When different subclasses use different prefixes, they can both be installed and operate independently.
.. data:: default_settings A dictionary of default settings. This is empty in :class:`~django_auth_ldap.backend.LDAPBackend`, but subclasses can populate this with values that will override the built-in defaults. Note that the keys should omit the ``'AUTH_LDAP_'`` prefix.
.. method:: populate_user(username) Populates the Django user for the given LDAP username. This connects to the LDAP directory with the default credentials and attempts to populate the indicated Django user as if they had just logged in. :setting:`AUTH_LDAP_ALWAYS_UPDATE_USER` is ignored (assumed ``True``).
.. method:: get_user_model(self) Returns the user model that :meth:`~django_auth_ldap.backend.LDAPBackend.get_or_build_user` will instantiate. By default, custom user models will be respected. Subclasses would most likely override this in order to substitute a :ref:`proxy model <proxy-models>`.
.. method:: authenticate_ldap_user(self, ldap_user, password) Given an LDAP user object and password, authenticates the user and returns a Django user object. See :ref:`customizing-authentication`.
.. method:: get_or_build_user(self, username, ldap_user) Given a username and an LDAP user object, this must return a valid Django user model instance. The ``username`` argument has already been passed through :meth:`~django_auth_ldap.backend.LDAPBackend.ldap_to_django_username`. You can get information about the LDAP user via ``ldap_user.dn`` and ``ldap_user.attrs``. The return value must be an (instance, created) two-tuple. The instance does not need to be saved. The default implementation looks for the username with a case-insensitive query; if it's not found, the model returned by :meth:`~django_auth_ldap.backend.LDAPBackend.get_user_model` will be created with the lowercased username. New users will not be saved to the database until after the :data:`django_auth_ldap.backend.populate_user` signal has been sent. A subclass may override this to associate LDAP users to Django users any way it likes.
.. method:: ldap_to_django_username(username) Returns a valid Django username based on the given LDAP username (which is what the user enters). By default, ``username`` is returned unchanged. This can be overridden by subclasses.
.. method:: django_to_ldap_username(username) The inverse of :meth:`~django_auth_ldap.backend.LDAPBackend.ldap_to_django_username`. If this is not symmetrical to :meth:`~django_auth_ldap.backend.LDAPBackend.ldap_to_django_username`, the behavior is undefined.
