AWS Identity Pool Attributes为身份池属性，可用于控制访问授权。身份池是一组针对AWS服务或应用程序的身份验证和授权信息。以下是使用Cognito身份池管理AWS访问控制的代码示例：

// Create an Identity Pool
val cognitoclient = AmazonCognitoIdentityClientBuilder.standard()
        .withRegion(Regions.US_WEST_2)
        .build()

val createIdentityPoolRequest = CreateIdentityPoolRequest().apply {
    identityPoolName = "MyPool"
}

val createIdentityPoolResult = cognitoclient.createIdentityPool(createIdentityPoolRequest)

// Set Identity Pool Attributes
val setCognitoIdentityProviderRequest = SetIdentityPoolRolesRequest().apply {
    identityPoolId = createIdentityPoolResult.identityPoolId
    roles = mapOf(
            "authenticated" to "arn:aws:iam::11111111111:role/MyAuthorizedRole"
    )
    cognitoIdentityProviders = listOf(
            CognitoIdentityProvider().apply {
                providerName = "cognito-idp.us-west-2.amazonaws.com/us-west-2_123456789"
                clientId = "abcdefghijklmno"
            }
    )
}

cognitoclient.setIdentityPoolRoles(setCognitoIdentityProviderRequest)

以上代码段首先创建了一个名为"MyPool"的身份池，然后设置了身份池的角色和Cognito身份提供者。在这种情况下，"MyAuthorizedRole"授予了验证过的用户授权。
