AUTH_REMOTE_USER is gone

[ghost]

Apache Airflow version

2.7.1

What happened

We upgraded from 2.6.3 to 2.7.1 and the webserver stopped working due to our config with error:

ImportError: cannot import name 'AUTH_REMOTE_USER' from 'airflow.www.fab_security.manager'

There's a commit called Fix inheritance chain in security manager (https://github.com/apache/airflow/pull/33901) which sounds suspicious around magic security imports.

What you think should happen instead

This is still documented and it wasn't noted in the changelog as removed, so it shouldn't have broken our upgrade.

How to reproduce

it's not there, so try to import it and... it's not there.

for now I just switched it to importing directly from flask_appbuilder.const import AUTH_DB, AUTH_LDAP, AUTH_OAUTH, AUTH_OID, AUTH_REMOTE_USER

Operating System

all of them

The mentioned commit is not released yet.

For this issue, IMHO importing from airflow.www.fab_security.manager is not a good practice, and these example code was added in 2.7.0 by #32759.

I will update the documentation.
