Azure Redis Cache结合Entra ID认证在.NET 8 API中的配置问题

我正尝试在.NET 8 API中集成Azure Redis Cache，已添加连接字符串并编写如下代码：

services.AddStackExchangeRedisCache(
    options =>
    {
        options.Configuration = builder.Configuration.GetConnectionString("RedisCache");
        options.InstanceName = builder.Environment.EnvironmentName;
    })
.AddDistributedMemoryCache();

当连接字符串中包含密码时该配置可正常工作，但我希望使用Entra ID认证替代密码。已启用Entra ID认证选项，为对应的Azure Web App分配了data owner权限，但移除密码后出现以下错误：

StackExchange.Redis.RedisConnectionException: 'The message timed out in the backlog attempting to send because no connection became available (5000ms) - Last Connection Exception: AuthenticationFailure on tsg-pas-dev-redis.redis.cache.windows.net:6380/Interactive, Flushed/ComputeResult, last: ECHO, origin: SetResult, outstanding: 0, last-read: 0s ago, last-write: 0s ago, keep-alive: 60s, state: ConnectedEstablishing, mgr: 9 of 10 available, last-heartbeat: never, global: 0s ago, v: 2.6.122.38350, command=SET, timeout: 5000, inst: 12, qu: 1, qs: 0, aw: False, bw: SpinningDown, rs: ReadAsync, ws: Flushed, in: 0, last-in: 0, cur-in: 0, sync-ops: 1, async-ops: 1, serverEndpoint: tsg-pas-dev-redis.redis.cache.windows.net:6380, conn-sec: 0.23, aoc: 0, mc: 1/1/0, mgr: 10 of 10 available, clientName: DBSX1Y6-54977(SE.Redis-v2.6.122.38350), IOCP: (Busy=1,Free=999,Min=8,Max=1000), WORKER: (Busy=1,Free=32766,Min=8,Max=32767), POOL: (Threads=15,QueuedItems=0,CompletedItems=347,Timers=3), v: 2.6.122.38350'

Exception: Error: NOAUTH Authentication required. Verify if the Redis password provided is correct. Attempted command: ECHO

请问我遗漏了什么配置？我记得其他服务需要在主程序中获取/初始化令牌，不确定是否与此相关。

根据下方回答我进行了修改，以便仍能使用IDistributedCache，本地可继续使用MemoryCache：

public static void AddDistributedCache(this IServiceCollection services, WebApplicationBuilder builder)
{
    if (builder.Configuration["UseMemoryCache"]?.Equals("yes", StringComparison.OrdinalIgnoreCase) ?? true)
    {
        services.AddDistributedMemoryCache();
    }
    else
    {
        services.AddStackExchangeRedisCache(options =>
        {
            options.InstanceName = builder.Environment.EnvironmentName;
            options.ConnectionMultiplexerFactory = () => ConnectionMultiplexerFactory(builder);
        })
        .AddDistributedMemoryCache();
    }
}

private static async Task<IConnectionMultiplexer> ConnectionMultiplexerFactory(WebApplicationBuilder builder)
{
    var configurationOptions = await ConfigurationOptions.Parse(builder.Configuration.GetConnectionString("RedisCache")!)
        .ConfigureForAzureWithTokenCredentialAsync("XXXX", new DefaultAzureCredential());

    var connectionMultiplexer = await ConnectionMultiplexer.ConnectAsync(configurationOptions);

    return connectionMultiplexer;
}

其中XXXX需要从appsettings获取，我尚不理解为何需要该参数，且在同一Redis实例多应用场景下不够便捷，但至少无需密码。优点是可轻松切换缓存，无需关注multiplexer的getDatabase等操作。
