Hi!

We're trying to install Apache Airflow v2.6.3 on a Kubernetes cluster of ours. 
As a part of the installation, we have webserver, scheduler, worker and redis 
pods deployed and using a pre-existing postgres DB that is present on a 
different server. We've got all the pods up and running and creation of the 
initial user and subsequent users via airflow CLI is also taking place. Via 
shell, we've checked the worker pods and it's getting connecting to Redis 
successfully as well (As stated in stdout). However, when we try to login via 
the created credentials, we're encountering Invalid Credentials error. We've 
tried updating the webserver_config.py to disable authentication and enable 
anonymous login with Admin privileges. But that configuration change still 
routes us to the login page for some reason. It seems as though 
webserver_config.py changes are not picked up by the webserver and something 
might be off as well. But not sure what. At the moment, we're mounting the 
config file via ConfigMap and giving 777 permission (since mounting takes place 
via root and the image is a bit bulky so we're unable to download, makes 
changes and commit). Could there be any specific reason to this? For 
airflow.cfg, we're mostly using ENV variables to set the values.

Note - Even API authentication is not working as expected. Authentication types 
already set by default for APIs within airflow.cfg file. The 
webserver_config.py file is mounted on the AIRFLOW_HOME directory. So no 
mistake there as well.

Thank you.
Warm Regards,
