[AIRFLOW-1021] Fix double login for new users with LDAP
By adding the new user to the session and commit
before merging, the correct user is returned by
`load_user(userid)` instead of `None` due to no
`id` assoicated with that user.
Closes #2778 from wolfier/AIRFLOW-1021
> Double logging required for new users with LDAP
> -----------------------------------------------
>
> Key: AIRFLOW-1021
> URL: https://issues.apache.org/jira/browse/AIRFLOW-1021
> Project: Apache Airflow
> Issue Type: Bug
> Components: contrib
> Affects Versions: Airflow 1.8
> Reporter: Marcelo G. Almiron
> Assignee: Alan Ma
> Priority: Major
>
> Every user needs to login twice to access Airflow for the first time with
> LDAP.
> In the first trial the user is not persistent, so there is no `id`
> associated, which leads to `None` value returned by `load_user(userid)`,
> since `userid` is none `None`.
> A quick fix is to add the new user to the session and commit before merging.
> That is, in module `airflow/contrib/auth/backends/ldap_auth.py`, we can
> change
> ```
> if not user:
> user = models.User(
> username=username,
> is_superuser=False)
> session.merge(user)
> session.commit()
> flask_login.login_user(LdapUser(user))
> ```
> by
> ```
> if not user:
> user = models.User(
> username=username,
> is_superuser=False)
> session.add(user)
>
> session.commit()
> session.merge(user)
> flask_login.login_user(LdapUser(user))
> ```
