Berislav Lopac created AIRFLOW-2209:
---------------------------------------
Summary: AttributeError: module
'airflow.contrib.auth.backends.password_auth' has no attribute 'login_required'
Key: AIRFLOW-2209
URL: https://issues.apache.org/jira/browse/AIRFLOW-2209
Project: Apache Airflow
Issue Type: Bug
Components: authentication
Reporter: Berislav Lopac
After updating to the latest {{master}}, the following error shows the error in
the title in {{airflow-webserver}} logs. Apparently, ~AIRFLOW-1760 has removed
`login_required` from the `password_auth` module, so the webserver fails.
h3. Steps to repeat:
1. Set in configuration
{code}
authenticate = True
auth_backend = airflow.contrib.auth.backends.password_auth
{code}
2. Run:
{code}AIRFLOW_HOME=/path/to/config airflow webserver{code}
The webserver fails with the error message:
{code:python}

AttributeError: module 'airflow.contrib.auth.backends.password_auth' has no
attribute 'login_required'
{code}
h3. Proposed solution
Restore import of `login_required` in
`airflow.contrib.auth.backends.password_auth`.
