Installation
============

Run ``pip install ldap-groups``

Add *ldap-groups* to ``INSTALLED_APPS``

.. code:: python

INSTALLED_APPS = (
...
'ldap_groups',
...
)


Django Settings
===============

There are a few settings that must be configured before ldap-groups will run.

*Mandatory*

* ``LDAP_GROUPS_SERVER_URI`` - The ldap server's uri, e.g. 'ldap://example.com'
* ``LDAP_GROUPS_BASE_DN`` - The base search dn, e.g. 'DC=example,DC=com'

*Optional*

* ``LDAP_GROUPS_BIND_DN`` - The bind user's DN
* ``LDAP_GROUPS_BIND_PASSWORD`` - The bind user's password

NOTE: while a bind user is optional, many servers' security settings will deny anonymous access.

* ``LDAP_GROUPS_USER_LOOKUP_ATTRIBUTE`` - The attribute by which to search when looking up users (should be unique). Defaults to ``'sAMAccountName'``.
* ``LDAP_GROUPS_ATTRIBUTE_LIST`` - A list of attributes returned for each member while pulling group members. An empty list should return all attributes. Defaults to ``['displayName', 'sAMAccountName', 'distinguishedName']``.


Usage
=====

In its current state, ldap-groups can perform the following functions:

* Add a member to a group
* Remove a member from a group
* Get all members of a group (and their attributes) [only retrieves user object classes at this point]
* Get all attributes of a group in dictionary form
* Get a specific attribute of a group
* Get all children of a group (groups and organizational units)
* Traverse to a specific child of a group
* Traverse to a group's parent
* Traverse to a group's ancestor


An ADGroup instance only requires one argument to function: a group's distinguished name.
Once the ADGroup is instantiated, the rest is fairly simple:

.. code:: python

from ldap_groups import ADGroup

GROUP_DN = "ou=users,dc=example,dc=com"
ACCOUNT_NAME = "jdoe"
NAME_ATTRIBUTE = "name"
TYPE_ATTRIBUTE = "objectClass"

class ADGroupModifier(object):

def __init__(self):
self.ad_group_instance = ADGroup(GROUP_DN)

def add_member(self):
self.ad_group_instance.add_member(ACCOUNT_NAME)

def remove_member(self):
self.ad_group_instance.remove_member(ACCOUNT_NAME)

def get_group_member_info(self):
return self.ad_group_instance.get_member_info()


class ADGroupInfo(object):

def __init__(self):
self.ad_group_instance = ADGroup(GROUP_DN)

def get_attributes(self):
return self.ad_group_instance.get_attributes()

def get_name(self):
return self.ad_group_instance.get_attribute(NAME_ATTRIBUTE)

def get_type(self):
return self.ad_group_instance.get_attribute(TYPE_ATTRIBUTE)

Running ldap-groups without Django
==================================

If ldap-groups is not used in a django project, the ADGroup object can be initialized with the following parameters:

.. code:: python

ADGroup(group_dn, server_uri, base_dn[, user_lookup_attr[, attr_list[, bind_dn, bind_password]]])


* ``group_dn`` - The distinguished name of the group to manage.
* ``server_uri`` - The ldap server's uri, e.g. 'ldap://example.com'
* ``base_dn`` - The base search dn, e.g. 'DC=example,DC=com'
* ``user_lookup_attr`` - The attribute by which to search when looking up users (should be unique). Defaults to ``'sAMAccountName'``.
* ``group_attr_list`` - A list of attributes returned for each member while pulling group members. An empty list should return all attributes. Defaults to ``['displayName', 'sAMAccountName', 'distinguishedName']``.
* ``bind_dn`` - The bind user's DN
* ``bind_password`` - The bind user's password
