我应该为 Amazon Keyspaces（托管 Cassandra）使用哪个用户名和密码？

Question

I am unable to connect to AWS Keyspaces using .NET Core due to an authentication error:

AuthenticationException 'Provided username nick and/or password are incorrect')

I am not sure what values I should give to PlainTextAuthProvider .

I have tried using:

• My AWS Console credentials
• AWS access key / secret key pair

How do I generate credentials for AWS Keyspaces?

My code, in case it is relevant:

open System
open Cassandra

[<EntryPoint>]
let main argv = 
  async {    
    let cluster =
      Cluster.Builder()
        .AddContactPoints("cassandra.eu-west-2.amazonaws.com")
        .WithPort(9142)
        .WithAuthProvider(PlainTextAuthProvider ("username", "password123"))
        .WithSSL()
        .Build()

    use! session =
      cluster.ConnectAsync ()
      |> Async.AwaitTask

    ()
  }
  |> Async.RunSynchronously

The option is found in the IAM section .

Naviagate to:

• "Services" drop-down
• Click "Identity and Access Management (IAM)"
• Open the "Users" tab
• Click on You username
• Open the "Security credentials" tab
• Scroll to the "Credentials for Amazon Keyspaces" section
• Click "Generate Credentials"

This will show a pop-up where you can generate credentials.

Additionally, the code should specify a Keyspace:

open System
open Cassandra

[<EntryPoint>]
let main argv = 
  async {    
    let cluster =
      Cluster.Builder()
        .AddContactPoints("cassandra.eu-west-2.amazonaws.com")
        .WithPort(9142)
        .WithAuthProvider(PlainTextAuthProvider ("username", "password123"))
        .WithSSL()
        .Build()

    use! session =
      cluster.ConnectAsync "test_keyspace"
      |> Async.AwaitTask

    ()
  }
  |> Async.RunSynchronously
