Configure SSO for Apps with AWS Cognito as IDP

---

AWS Cognito Single Sign-On (SSO) solution by miniOrange allows users to login into multiple applications using an existing username and password of Cognito. Here AWS Cognito will act as an Identity Provider (IDP) and your applications will act as a Service Provider (SP). miniOrange acts as a broker to communicate with IDP and SP and provide secure login access to users.
AWS Cognito handles the responsibility of authenticating users within the application, making it easier for admins to integrate SSO into their applications. Overall this eliminates the need to manage different identities as all information is stored in a unified location - AWS Cognito. Once Cognito SSO is configured, you will be able to :

• SSO login to your Cloud, On-Premise, and in-house apps using Cognito credentials
• Cross Protocol Authentication (Connect app supporting different protocols to IDP supporting different protocols)
• Attribute Mapping
• Multiple IDP Connection

Follow the Step-by-Step Guide given below for AWS Cognito Single Sign-On (SSO)

1. Configure AWS Cognito as OAuth 2.0 Provider in miniOrange.

• Go to miniOrange Admin Console.
• From the left navigation bar select Identity Provider. Select Oauth





• Enter the following values.

IdP Name	Custom Provider
IdP Display Name	Choose appropriate Name
OAuth Authorize Endpoint	https://{cognito-app-domain}/oauth2/authorize
OAuth Access Token Endpoint	https://{cognito-app-domain}/oauth2/token
OAuth Get User Info Endpoint (optional)	https://{cognito-app-domain}/oauth2/userInfo
Client ID	From step 2
Client secret	From step 2

2. Configure AWS Cognito as Userstore OR IDP in miniOrange

• Configure AWS Cognito as IDP in miniOrange
• Configure AWS Cognito as Userstore in miniOrange

1.1 Configuring miniOrange as Service Provider (SP) in AWS Cognito

Note: Choose the Authorization Endpoint according to the identity source you configure.

• When you want to use you want to use miniOrange as OAuth identity server use this endpoint: https://{mycompany.domainname.com}/moas/idp/openidsso
• If you are configuring any Identity Provider in Identity Providers Menu and not using miniOrange as IDP use this endpoint: https://{mycompany.domainname.com}/broker/login/oauth{customerid}

• Click on Create App under JWT.



• Select JWT App.



• Configure the name for your application and configure Redirect-URL which tells where to send JWT response. Redirect-URL should be an endpoint on your application where you want to achieve SSO.




In case you are setting up SSO with Mobile Applications where you can't create an endpoint for Redirect or Callback URL, use below URL.

https://login.xecurify.com/moas/jwt/mobile


• Click Save
• To get the SSO link for your application, Go to Apps >> your_app >> select >> Edit.



• Then, copy the Single Sign On Url and verify SSO setup by browsing that url.



• On successful authentication, you will be redirected to configured Redirect or Callback URL with JWT token
• You will need to download a certificate from App > Manage Apps, and click Certificate link against your configured application. This certificate will be used for signature validation of JWT response.

4. Login using IDP selection page (Optional)

• You can configure multiple IDPs (Identity Providers) and give users the option to select the IDP of their choice to authenticate with.
  For Example - It could be multiple AD domains belonging to different departments or multiple okta organizations.

Few usecases where customers configure multiple IDPs -


• Suppose you have a product which many of your clients use and each client has their own unique IDP so you want them to SSO into your product as well using their existing IDP only. miniOrange provides a centralized way to connect with all IDPs in a very easy manner and integrate SSO into your application.
• Suppose you are providing a course to many universities, each having a unique SAML, OAuth protocol supported IDP's like Shibboleth, ADFS, CAS, etc. You can provide Single Sign-On (SSO) into your course application to all these universities by integrating with all of them using a single platform provided by miniOrange.
• This is the endpoint to call from your SAML application -

For Cloud IDP -	https://login.xecurify.com/moas/discovery?customerId=<customer_id>
For On-Premise IDP -	https://yourdomain.com/discovery?customerId=<customer_id>



• You should copy the Customer Key from admin console-> Settings -> and replace it with <customer_id> here. Once configured in SP, when you initiate the login from Service Provider, a user will be redirected to IDP Selection Page listing all IDPs configured for that account.

You can see the screenshot below of the IDP Selection Page with a list of IDPs.




Note: To view the IDP in drop-down list, go to Identity Providers tab > against your configured IDP > Select >Edit , here Enable the Show IdP to Users option.




• You can also change the look and feel of this page. Login to miniOrange Admin console. Navigate to Customization -> Branding Configuration. See the below screenshot for reference-




• You can customize the title of this page.
• Change the logo and favicon for this page.
• Change the background and button color for this page from admin UI.
