Rodrigo507 opened a new issue #21847:
URL: https://github.com/apache/airflow/issues/21847
### Apache Airflow version
2.2.3
### What happened
I am trying to enable user registration, by configuring the
"webserver_config.py" file.
I have set the AUTH_USER_REGISTRATION variable to True and I have restarted
the "webserver" container. I also tried performing down to the services and
again up to the services and the error continues.
Once enabled the variable already mentioned in the "Login" panel the
Register button is shown, but when accessing the "Register" it shows the
following error.
```
Traceback (most recent call last):

datamodel_user = self.appbuilder.sm.get_user_datamodel
AttributeError: 'AirflowSecurityManager' object has no attribute
'get_user_datamodel'
```
I should add that both the "airflow.cfg" and "webserver_config.py" file I
have as volume so as not to lose the configuration.
### What you expected to happen
That users have a form where they must fill out the registration
information, and then be able to access
### How to reproduce
The variable AUTH_USER_REGISTRATION = True must be enabled in the file
"webserver_config.py", verify that the variable AUTH_TYPE has AUTH_DB as value
and finally validate that AUTH_DB is imported.
