Authentication failure with v5.0

[nwoods]

Version: redis-py 5.0.0, redis 5.0.7-2ubuntu0.1

Platform: Ubuntu 20.04

Description:

The following script works with redis-py 4.6.0 but throws redis.exceptions.AuthenticationError: Authentication required. with redis-py 5.0.0:

from redis import Redis

if __name__ == '__main__':
    redis = Redis(
        host='xxx',
        port=1234,
        ssl=True
    )
    redis.auth('xxx', 'xxx')
    if redis.ping():
        print('success')

(I obviously changed the host, port, username, and password).

This is using Ubuntu 20.04, and apt list shows the redis version as 5.0.7-2ubuntu0.1.

I'm not sufficiently knowledgeable to guess what information about the redis server would be useful, so please let me know.

Stack trace from v5.0:

@dvora-h bump

@nwoods Ideally you wouldn't authenticate this way. Auth should happen during the construction of redis.Redis, as username and password are supported there.

@dvora-h either way, please have a look
