• And more...

Database storage

Support is provided for the following Database engine.

• InMemory (default)
• MongoDB
• SqlServer
• MySql

Gettings Started

By default, the application will run with the following settings

• InMemory data storage
• Email are sent to the console output
• No Google Recaptcha
• No OAuth providers
• Two (2) demo clients created for OpenIdDict

Those settings can be changed using standard configuration mechanism.

Run locally

From root directory,

cd src/Nuages.Identity.UI
dotnet run

Application will be available at https://localhost:8001

Run locally with Docker

From the root directory,

docker build -t nuages.identity.ui .
docker run -it --rm -p 8003:80 --env-file ./env.list --name nuage-identity nuages.identity.ui

Application will be available at http://localhost:8003 (no HTTPS)

Note: env.list must include environment variables required to run the app (see Configuration below)

Deployment

The application can be deployed using standard ASP.NET Core mechanism.

The sample site https://identity.nuages.org is deployed on AWS with ECS using the following CDK project.

https://github.com/nuages-io/nuages-deploy-ecs-cdk

Configuration

Configuration is done using the standard Configuration system. You may want to use one of the following ways to customize the application.

• Change appsettings.json
• Add a appsettings.local.json and/or appesettings.prod.json (those file are not added to git)
• Use environment variables
• If using AWS
  • You may use AppConfig
  • You may use ParameterStore

Using AWS SecretManager

You can use a secret instead of a string value for any configuration value.

Ex. Let's says you want to hide the database connection string

So instead of

{
  "Nuages": {
    "Data": {
      "ConnectionString": "my connection string value"
    }
  }
}

You can swap the value for a secret ARN (the ARN can be found in your AWS account)

{
  "Nuages": {
    "Data": {
      "ConnectionString": "arn:aws:secretsmanager:{region}:{account_id}:secret:identity/mongo-ABC123"
    }
  }
}

Only string values are supported.

Restrictions

Some restrictions apply compare to the default ASP.NET identity implementation.

1. A phone number cannot be used as the primary 2FA method. It can only be used as a fallback mechanism.
2. It is not possible to require a verified phone number to login
3. User's email cannot be different from the username if the username is an email.
4. Email must be unique system wide
