LDAP issue logging into Superset (no attribute 'login_count')

See original GitHub issue

I can’t login to Superset with a user that is not registered in the DB. It is failing in the user registration code of fab.

My config entries:

AUTH_TYPE = 2
AUTH_LDAP_SERVER = "ldap://x.x.x.x"
AUTH_LDAP_SEARCH = "OU=someusers,OU=another,DC=somedomain,DC=com"
AUTH_LDAP_UID_FIELD = "userPrincipalName"
AUTH_USER_REGISTRATION = True
AUTH_USER_REGISTRATION_ROLE = 'alpha'

I can get my AD details using the python-ldap library much like the code does in manager.py. The following code run against MSFT AD works fine:

import ldap
con =  ldap.initialize(AUTH_LDAP_SERVER)
con.bind_s("auser@somedomain.com", "pass")
con.search_s(AUTH_LDAP_SEARCH,ldap.SCOPE_SUBTREE,"userPrincipalName=auser@somedomain.com", ['givenName', 'sn', 'mail'])

But when I try to login I get following message:

Error:

    if not user.login_count:
AttributeError: 'bool' object has no attribute 'login_count'
Exception on /login/ [POST]

I don’t know why the user object is a bool.
