Motivation:
This thread helped me a lot to get started.
Because of this, here is a little write up on where I went with it:
Goal:
Use AD groups to give selective access in Icingaweb2 and use the same groups for Notifications.
Problem:
This is bad! As required by AGDLP, we have business groups as members of permission groups.
Impossible with only the director I would guess:

My solution for the moment:
https://github.com/Icinga/icingaweb2-module-fileshipper
And this quick hacked together script:
#!/usr/bin/env python3
# vim: set fileencoding=utf-8 ts=4 sw=4 sts=4 et :
from ldap3 import Server, Connection, ALL, NTLM
from ldap3.utils.conv import escape_filter_chars
import json
import sys
server = Server('ADSERVER', use_ssl=True, get_info=ALL)
def get_user_groups(dn):
with Connection(server, user="BINDUSER", password="BINDPW", authentication=NTLM) as conn:
dn = escape_filter_chars(dn)
conn.search(
search_base='SEARCHBASE',
search_filter='(member:1.2.840.113556.1.4.1941:=%s)' % dn,)
return conn.entries
with Connection(server, user="BINDUSER", password="BINDPW", authentication=NTLM) as conn:
conn.search(
search_base='SEARCHBASE',
search_filter='\
(&\
(memberOf:1.2.840.113556.1.4.1941:=DNOFMAINGROUP)\
(!(userAccountControl:1.2.840.113556.1.4.803:=2))\
(mail=*)\
(objectClass=user)\
)',
attributes=[
'SamAccountName',
'displayName',
'mail',
]
)
#print(conn.entries[0].entry_dn)
icinga_users = []
for user in conn.entries:
user_json = user.entry_to_json()
user_dict = json.loads(user_json)
user_dict.update(user_dict['attributes'])
del user_dict['attributes']
user_dict['groups'] = []
#print(user_dict)
groups = get_user_groups(user.entry_dn)
for group in groups:
group_json = group.entry_to_json()
group_dict = json.loads(group_json)
#print(group_dict)
user_dict['groups'].append(group_dict['dn'])
#print(json.dumps(user_dict, indent=4, sort_keys=True))
icinga_users.append(user_dict)
#break
#print(json.dumps(icinga_users, indent=4, sort_keys=True))
with open('icinga_users.json', 'w') as outfile:
json.dump(icinga_users, outfile)
Replace the following with your values:
- ADSERVER
- BINDUSER
- BINDPW
- DNOFMAINGROUP - I had to put all my icinga permisson groups in to one group - this is the one to rule them all
Next some cleanup. My Icingaweb2 permission groups have a ICT_Icinga_P prefix.

Groups are easy and and don’t requre a external script The use of:
(&(memberOf:1.2.840.113556.1.4.1941:=DNOFMAINGROUP)(objectClass=group))
in the disector source ldap query was enough for me. The cleanup details are left as excercise to the reader…
