Activate user checkbox fails when using LDAP authentication.

[gadam0]

I am running Caravel 0.10.10 and I am using AUTH_LDAP for user authentication.

After I add a user from the web UI, clicking the checkbox to toggle the user's active status produces this stack trace.

Traceback (most recent call last):
  File "$PREFIX/lib/python2.7/site-packages/caravel/views.py", line 65, in wraps
    return f(self, *args, **kwargs)
  File "$PREFIX/lib/python2.7/site-packages/flask_appbuilder/security/decorators.py", line 52, in wraps

    model_view_cls = getattr(views, model_view)
AttributeError: 'module' object has no attribute 'UserLDAPModelView'

This is the request that causes the exception.

This is the section where the error is occurring.

Would importing the built-in views from flask appbuilder into the views module be the best solution or is there a better fix?

from flask_appbuilder.security.views import *
