A python/django Active Directory group management abstraction that uses python3-ldap as a backend for cross-platform compatibility.

Project description

Version: 4.1.0
Dependencies:Python 2.7+, 3.2+, python3-ldap>=0.9.6
Home page:https://bitbucket.org/kavanaugh_development/ldap-groups
Author: Alex Kavanaugh <kavanaugh.development@outlook.com>

Installation

Run pip install ldap-groups

Add ldap-groups to INSTALLED_APPS

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_USER_SEARCH_BASE_DN - The base dn to use when looking up users. Defaults to LDAP_GROUPS_BASE_DN.
  • LDAP_GROUPS_GROUP_LOOKUP_ATTRIBUTE - The attribute by which to search when looking up groups (should be unique). Defaults to 'name'.
  • LDAP_GROUPS_GROUP_SEARCH_BASE_DN - The base dn to use when looking up groups. Defaults to LDAP_GROUPS_BASE_DN.
  • 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:

  • Get a specific attribute of a group
  • Get all attributes of a group in dictionary form
  • Get all members of a group and their attributes (users)
  • Add a member to a group (user)
  • Remove a member from a group (user)
  • Add a child to a group (nested group)
  • Remove a child from a group (nested group)
  • Get all descendants of a group (groups and organizational units)
  • 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:

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:

ADGroup(group_dn, server_uri, base_dn[, user_lookup_attr[, group_lookup_attr[, attr_list[, bind_dn, bind_password[, user_search_base_dn[, group_search_base_dn]]]]]])
  • 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_lookup_attr - The attribute by which to search when looking up groups (should be unique). Defaults to 'name'.
  • 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
  • user_search_base_dn - The base dn to use when looking up users. Defaults to LDAP_GROUPS_BASE_DN.
  • group_search_base_dn - The base dn to use when looking up groups. Defaults to LDAP_GROUPS_BASE_DN.
