NOAUTH Authentication required when use go-redis connect dragonfly

[ly269nva]

i want use go-redis/v9 to connect dragonfly (redis_version:df-v0.15.0, a db like redis), but i go a err : NOAUTH Authentication required.
but it ok when i use go-redis/v9 to connect my local redis,
and it also ok when i use go-redis/v8 to connect dragonfly.
this is a bug? why go-redis/v9 not support dragonfly with password?
`
var redisdb *redis.Client

redisdb = redis.NewClient(&redis.Options{
Addr: "127.0.0.1:6379", // 指定
Password: "1234",
DB: 2, // redis一共16个库，指定其中一个库即可
PoolSize: 2000,
})

t.Log(redisdb.Info(context.Background()))
`

I don't know the dragonfly system, let me introduce the difference between go-redis v8 and v9:

v8:

if c.opt.Password != "" {
	if c.opt.Username != "" {
		pipe.AuthACL(ctx, c.opt.Username, c.opt.Password)
	} else {
		pipe.Auth(ctx, c.opt.Password)
	}
}

v9 first uses the HELLO username password command for authentication, and if it fails, then use the authentication method of the v8 version.
