Connecting to a sentinel Redis 5.0.7 fails with NOAUTH Authentication required

[kalyashov]

I am trying to connect to the sentinel node of a Redis and I am getting the error:

docker-compose.yml to launch redis containers:

version: '2'

networks:
  app-tier:
    driver: bridge

services:
  redis:
    image: 'redislabs/redisearch:latest'
    environment:
      - REDIS_PASSWORD=12345678
    ports:
      - '6379:6379'
    networks:
      - app-tier
  redis-sentinel:
    image: 'bitnami/redis-sentinel:latest'
    environment:
      - REDIS_MASTER_HOST=127.0.0.1
      - REDIS_MASTER_PASSWORD=12345678
      - REDIS_SENTINEL_PASSWORD=12345678
    ports:
      - '26379:26379'
    networks:
      - app-tier

The settings in the spring-boot app to connect Redis:

  redis:
    port: 6379
    database: 0
    host: localhost
    mutex-timeout: 300s
    command-timeout: 10s
    sentinel:
      master: mymaster
      nodes: 127.0.0.1:26379
      password: 12345678
    password: 12345678

I see that the redisURI in the RediSearchClient is formed correctly

I also see a connection that is formed in the RediSearchClient, it does not contain a password, what is this password?
I tried to set it in debug, but the authentication error remained.

The password to Redis is correct:

I checked that the password to Redis is correct and also when I configure sentinel Redis without password there are no connection errors.

I see similar issues:

• Connecting to a sentinel Redis 5.0.1 server fails with NOAUTH Authentication required redis/lettuce#1001
• Add support for Redis Sentinel authentication redis/lettuce#1002
• RedisURI class does not parse password when using redis-sentinel redis/lettuce#1232
  But they don't have a solution for me

I think that problem in RediSearchClient, this is my modified RediSearchClient, which is successfully connected to redis sentintel.
I copied RedisClient from lettuce and changed the interfaces, but I haven't found the exact location of the problem yet

Thank you for reporting the issue and submitting the fix. I incorporated this in v2.4.2
