LDAP Setup

For those who need to setup a LDAP server for development or production use:

pip3 install ansible
git clone https://github.com/peppelinux/ansible-slapd-eduperson2016.git
cd ansible-slapd-eduperson2016
ansible-playbook -i "localhost," -c local playbook.yml

Note: The playbook will backup any existing slapd installations in backups folder.

Setup

Create an virtual environment and activate it

pip3 install virtualenv

export PROJ_NAME=django-ldap-academia-ou-manager
export DEST_DIR=$PROJ_NAME.env
virtualenv -p python3 $DEST_DIR
source $DEST_DIR/bin/activate
pip3 install django

Install dependencies

apt install python3-dev python3-pip python3-setuptools
apt install libsasl2-dev python-dev libldap2-dev libssl-dev
pip install git+https://github.com/peppelinux/django-ldapdb.git
pip install git+https://github.com/peppelinux/pySSHA-slapd.git
pip install pycountry
pip install git+https://github.com/silentsokolov/django-admin-rangefilter.git
pip install git+https://github.com/peppelinux/django-ldap-academia-ou-manager.git

Create a project

django-admin startproject $PROJ_NAME
cd $PROJ_NAME

Install the app

Note: It uses a django-ldapdb fork to handle readonly (non editable) fields.

# pip3 install git+https://github.com/peppelinux/django-ldapdb.git
pip3 install git+https://github.com/peppelinux/django-ldap-academia-ou-manager

Edit settings.py

Read settings.py and settingslocal.py in the example folder.

In settings.py do the following:

• Add ldap_peoples in INSTALLED_APPS;
• Add rangefilter in INSTALLED_APPS;
• import default ldap_peoples settings as follows;
• import default app url as follows;

import default ldap_peoples settings

# settings.py
if 'ldap_peoples' in INSTALLED_APPS:
    from ldap_peoples.settings import *

import default app url

# urls.py
if 'ldap_peoples' in settings.INSTALLED_APPS:
    import ldap_peoples.urls
    urlpatterns += path('', include(ldap_peoples.urls, namespace='ldap_peoples')),

Using the Object Relation Mapper

One of the advantage of using the ORM is the possibility to make these kind of queries to a LDAP database.

User update attributes

from ldap_peoples.models import LdapAcademiaUser
lu = LdapAcademiaUser.objects.get(uid='mario')

# as multivalue
lu.eduPersonAffiliation.append('alumn')
lu.save()

lu.set_password('secr3tP4ss20rd')

# search into multivalue field
other_lus = LdapAcademiaUser.objects.filter(mail_contains='unical')

User creation example

# user creation
import datetime

d = {'cn': 'pedppe',
     'displayName': 'peppde Rossi',
     'eduPersonAffiliation': ['faculty', 'member'],
     'eduPersonEntitlement': ['urn:mace:terena.org:tcs:escience-user',
      'urn:mace:terena.org:tcs:personal-user'],
     'eduPersonOrcid': '',
     'eduPersonPrincipalName': 'grodsfssi@unical',
     'eduPersonScopedAffiliation': ['[email protected]', '[email protected]'],
     'givenName': 'peppe',
     'mail': ['[email protected]', '[email protected]'],
     'sambaNTPassword': 'a2137530237ad733fdc26d5d7157d43f',
     'schacHomeOrganization': 'testunical.it',
     'schacHomeOrganizationType': ['educationInstitution', 'university'],
     'schacPersonalUniqueID': ['urn:schac:personalUniqueID:IT:CF:CODICEFISCALEpe3245ppe'],
     'schacPlaceOfBirth': '',
     'sn': 'grossi',
     'telephoneNumber': [],
     'uid': 'perrrppe',
     'userPassword': '{SHA512}oMKZtxqeWdXrsHkX5wYBo1cKoQPpmnu2WljngOyQd7GQLR3tsxsUV77aWV/k1x13m2ypytR2JmzAdZDjHYSyBg=='}

u = LdapAcademiaUser.objects.create(**d)
u.delete()

Unit test

./manage.py test ldap_peoples.tests.LdapAcademiaUserTestCase

TODO

• form .clean methods could be cleaned with a better OOP refactor on FormFields and Widgets;

Django-ldapdb related

• We use custom django-ldapdb fork because readonly fields like createTimestamps and other are fautly on save in the official django-ldapdb repo. See related PR;
• ListFields doesn't handle properly verbose_name. It depends on the form class, we use our fork for elude this;
• Aggregate lookup for evaluating min max on records, this come from django-ldapdb;
