This is a Django authentication backend that authenticates against an LDAP
service. Configuration can be as simple as a single distinguished name template,
but there are many rich configuration options for working with users, groups,
and permissions.

This version is supported on Python 2.6, 2.7, 3.3, and 3.4; and Django >= 1.3.
Under Python 2, it requires `python-ldap
<https://pypi.python.org/pypi/python-ldap>`_ >= 2.0; under Python 3, it uses
`pyldap <https://pypi.python.org/pypi/pyldap>`_.

Full documentation can be found at
http://pythonhosted.org/django-auth-ldap/; following is an example
configuration, just to whet your appetite::

    import ldap
    from django_auth_ldap.config import LDAPSearch, GroupOfNamesType


    # Baseline configuration.
    AUTH_LDAP_SERVER_URI = "ldap://ldap.example.com"

    AUTH_LDAP_BIND_DN = "cn=django-agent,dc=example,dc=com"
    AUTH_LDAP_BIND_PASSWORD = "phlebotinum"
    AUTH_LDAP_USER_SEARCH = LDAPSearch("ou=users,dc=example,dc=com",
        ldap.SCOPE_SUBTREE, "(uid=%(user)s)")
    # or perhaps:
    # AUTH_LDAP_USER_DN_TEMPLATE = "uid=%(user)s,ou=users,dc=example,dc=com"

    # Set up the basic group parameters.
    AUTH_LDAP_GROUP_SEARCH = LDAPSearch("ou=django,ou=groups,dc=example,dc=com",
        ldap.SCOPE_SUBTREE, "(objectClass=groupOfNames)"
    )
    AUTH_LDAP_GROUP_TYPE = GroupOfNamesType()

    # Simple group restrictions
    AUTH_LDAP_REQUIRE_GROUP = "cn=enabled,ou=django,ou=groups,dc=example,dc=com"
    AUTH_LDAP_DENY_GROUP = "cn=disabled,ou=django,ou=groups,dc=example,dc=com"

    # Populate the Django user from the LDAP directory.
    AUTH_LDAP_USER_ATTR_MAP = {
        "first_name": "givenName",
        "last_name": "sn",
        "email": "mail"
    }

    AUTH_LDAP_USER_FLAGS_BY_GROUP = {
        "is_active": "cn=active,ou=django,ou=groups,dc=example,dc=com",

        "is_superuser": "cn=superuser,ou=django,ou=groups,dc=example,dc=com"
    }

    # Use LDAP group membership to calculate group permissions.
    AUTH_LDAP_FIND_GROUP_PERMS = True

    # Cache group memberships for an hour to minimize LDAP traffic
    AUTH_LDAP_CACHE_GROUPS = True
    AUTH_LDAP_GROUP_CACHE_TIMEOUT = 3600


    # Keep ModelBackend around for per-user permissions and maybe a local
    # superuser.
    AUTHENTICATION_BACKENDS = (
        'django_auth_ldap.backend.LDAPBackend',
        'django.contrib.auth.backends.ModelBackend',
