1. Is this request related to a challenge you're experiencing? Tell me about your story.

I was trying to use Redis Cluster authentication in an environment where the Redis cluster requires both a username and a password (ACL-based authentication).

Currently, the configuration only allows passing a single password value. In our setup, attempting to concatenate the username with the password (for example, username:password) results in authentication failure, because Redis Cluster expects the username to be provided explicitly rather than embedded in the password field.

This limitation makes it impossible to connect to Redis clusters that enforce ACL authentication with non-default users. As a result, we cannot use this component in environments where Redis security is configured according to modern Redis best practices.

It would be very helpful to introduce a dedicated configuration option such as REDIS_CLUSTER_USERNAME, allowing the username and password to be passed separately during authentication. This change would improve compatibility with Redis Cluster deployments that rely on ACLs and avoid fragile workarounds.
