A python/django Active Directory group management abstraction that uses ldap3 as a backend for cross-platform compatibility.
Install ldap-groups with pip:
pip install ldap-groupsAdd ldap-groups to INSTALLED_APPS (if you're using Django)
INSTALLED_APPS = (
...
'ldap_groups',
...
)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 DNLDAP_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 toLDAP_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 toLDAP_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'].
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"
