[Solved]-How to achieve authentication with django-auth-ldap?

Here’s a snippet from one of our sites.

# Django Auth Ldap
main_dn = 'dc=____,dc=organisation,dc=com'
groups_dn = 'ou=Groups,'+main_dn
users_dn = 'ou=Users,'+main_dn

AUTHENTICATION_BACKENDS = (
    'django_auth_ldap.backend.LDAPBackend',
    'django.contrib.auth.backends.ModelBackend',
)

AUTH_LDAP_SERVER_URI = "ldap://ldap.organisation.com"
AUTH_LDAP_BIND_DN = 'cn=___,'+main_dn
AUTH_LDAP_BIND_PASSWORD = "__________________"
AUTH_LDAP_USER_SEARCH = LDAPSearch(users_dn, 2, "(uid=%(user)s)")
AUTH_LDAP_USER_ATTR_MAP = {
    "first_name": "givenName",
    "last_name": "sn",
    "email": "mail"
}
AUTH_LDAP_MIRROR_GROUPS = True
AUTH_LDAP_ALWAYS_UPDATE_USER = True
AUTH_LDAP_GROUP_TYPE = PosixGroupType()
AUTH_LDAP_GROUP_SEARCH = LDAPSearch(groups_dn, ldap.SCOPE_SUBTREE, "(objectClass=posixGroup)")

AUTH_LDAP_USER_FLAGS_BY_GROUP = {
    "is_staff":         "cn=admins,"+groups_dn,
    "is_superuser":     "cn=developers,"+groups_dn,
}

EDIT:

Since the question is “What do i need in my views?”, The answer is that this config will save the user’s uid as the username field on the User model, so in your views, you need

uid = request.user.username

Hopefully this gets you up and running.

Since django-auth-ldap is a normal Django authentication backend, request.user should be set to the authenticated user (assuming you have the standard middleware installed—see the Django docs). With a typical setup, request.user.username will be the uid of the user’s DN. If you need more information, you can get it from request.user.ldap_user.

I’m not use django-auth-ldap, i write my own ldap authentification backend’s.

#define your backend authentification
AUTHENTICATION_BACKENDS = (
    'netipa.managment.ldapwm.netipaldapdjango.NetIpaLdap',
    #'django.contrib.auth.backends.ModelBackend ',
)

For more information about extend the User model, see https://docs.djangoproject.com/en/1.5/topics/auth/customizing/#specifying-a-custom-user-model

Here is my extend User Class Model

from django.db import models
from django.contrib.auth.models import AbstractUser

# Create your models here.

class LdapUsers(AbstractUser):
    ldap_id = models.IntegerField()
    ldap_mail = models.EmailField()
