BMFH opened a new issue, #28919:
URL: https://github.com/apache/airflow/issues/28919
### Apache Airflow version
2.5.0
### What happened
Configured AUTH_DB authentication for web server and Kerberos authentication
for API. Web server works well.
Try to get any API endpoint and get an error 500. I see Kerberos
authentication step is done, but authorization step fails.
'User' object (now it is just a string) doesn't have such parameter.
Request error
```

```
I tried to skip rights check, commenting problem lines and returning True
from has_access function and if I remember it right in one more function from
security.py. And I got it working. But it has been just a hack to check where
is the problem.
### What you think should happen instead
It should return right json answer with code 200.
### How to reproduce
1. webserver_config.py: default
2. airflow.cfg changed lines:
```
[core]
security = kerberos
[api]
auth_backends =
airflow.api.auth.backend.kerberos_auth,airflow.api.auth.backend.session
[kerberos]
ccache = /tmp/airflow_krb5_ccache
principal = airflow/nginx-test.mycompany
reinit_frequency = 3600
kinit_path = kinit
keytab = /root/airflow/airflow2.keytab
forwardable = True
include_ip = True
[webserver]
base_url = http://localhost:10000
web_server_port = 10000
```
3. Create keytab file with airflow principal
4. Log in as domain user, make request (for example):
curl --verbose --negotiate -u : http://nginx-test.mycompany:10000/api/v1/dags
