Background of the problem: I am using Redis backend for Django cache and getting this error on Django admin page login:
```
redis.exceptions.ResponseError: WRONGPASS invalid username-password pair or user is disabled.
```

and my redis connection URL was set to `redis://SECRETPWD@redis-host:6379`

The solution of the problem:
set redis connection URL to `redis://default:SECRETPWD@redis-host:6379`
