how can solved ?

my setup:

pymongo = 2.7 mongoengine = 0.8.8 mongodb = 3.0.3 python = 3.3.5 django = 1.6

database section of settings.py:

import mongoengine  databases = {     'default': {         'engine': '',         'name': 'test',     }, }   session_engine = 'mongoengine.django.sessions' # optional  _mongodb_user = 'root' _mongodb_passwd = 'root' _mongodb_host = '127.0.0.1' _mongodb_name = 'test' _mongodb_database_host = \     'mongodb://%s:%s@%s/%s' \     % (_mongodb_user, _mongodb_passwd, _mongodb_host, _mongodb_name)  mongoengine.connect(_mongodb_name, host=_mongodb_database_host)  authentication_backends = (     'mongoengine.django.auth.mongoenginebackend', )

i think problem mongoengine <= 0.9.0 not support new security algorithm used mongo3+ versions scram-sha-1 mongo2.x verions used mongodb-cr.

i first created user mongodb 2.6.7 using command 

> use mydatabase > db.adduser("username","secretpass")

and started mongodb v3.0.4 server on same dbpath. till have been able save document using django 1.8 app. update if goes wrong.
