Description

Redis extension allows to set auth with username and password (ext doc)
it's required if redis server uses ACL

RedisAdapter::createConnection should pass dsn username:password part to Redis::auth method as array (like ['username', 'password'])

Example

// somewhere outside
RedisAdapter::createConnection('redis://acl_user_name:acl_user_password@redis_host')

// somewhere inside RedisAdapter::createConnection
$redis->auth(['acl_user_name', 'acl_user_password'])
