A simple recipe to read objectGUID field from an active directory object on django-ldapdb.

objectGUID support on django-ldapdb

from ldapdb.models.fields import CharField
from uuid import UUID

def guid2string(val):
    """ convert an active directory binary objectGUID value as returned by
    python-ldap into a string that can be used as an LDAP query value """
    s = UUID(bytes_le=val)
    return s


class GUIDField(CharField):
    """
    Field with support for Binary objectGUID support on ActiveDirectory.
    """
    def from_ldap(self, value, connection):
        if len(value) == 0:
            return ''
        else:
            return guid2string(value[0])

class LdapComputer(ldapdb.models.Model):
    base_dn = "dc=X,dc=X"
    object_classes = ['computer']
    id = GUIDField(db_column='objectGUID', unique=True, primary_key=True)
