Seems to be a bug in Django, which assumes that user ids are always ints, which would make sense for a relational database. In the case of using Mongodb, the key or _id is going to be an object ID.

There are open bugs on this, which seem to pop up over again (for instance, this one https://code.djangoproject.com/ticket/14881 ) . For the moment, I've added a comment to this one ( https://github.com/pinax/django-user-accounts/issues/103 ) in django user accounts, which seems to be a good fit.

It may require a patch to fix.

Oddly enough, I had it working with django 1.5, with mongoengine, but after upgrading to django 1.6.1, the issue is back.
