Configure AWS Cognito as OAuth IDP for SSO

miniOrange Identity Broker service solution enables cross protocol authentication. You can configure AWS Cognito as an IDP for Single Sign-On (SSO) into your applications/websites. Here, AWS Cognito will act as an Identity Provider (IDP) and miniOrange will act as a broker.

We offer a pre-built solution for integrating with AWS Cognito, making it easier and quick to implement. Our team can also help you set up AWS Cognito as OIDC IDP to login into your applications.

Troubleshooting

You receive these error message when you try to SSO in to an application that has been set up to use AWS Cognito as External IdP using OAuth based Single Sign-On (SSO).

Error - Invalid redirect_uri

This error occurs when the redirect URI specified in the authentication request doesn’t match the one registered in Cognito.

Verify that the correct redirect URI is configured under App Client Settings in the AWS Cognito console.
Ensure the redirect URL in your OAuth client matches exactly with the one in Cognito, including case sensitivity.

Error - invalid_client

This error typically arises when the Client ID or Client Secret in the OAuth request is incorrect.

Double-check the Client ID and Secret values in the App Clients section of your Cognito user pool and ensure they are used correctly in your application's OAuth requests.

Error - Missing required scopes

If your OAuth request lacks necessary scopes (e.g., 'openid', 'email', or 'profile'), AWS Cognito will throw this error.

Go to App Client Settings in the Cognito user pool and ensure the relevant Auth scopes are enabled.
Also, confirm the scopes are included in your OAuth authorization request.

Error - invalid_grant

This error often occurs if there is an issue with the authorization code or refresh token used to get tokens.

It can happen if the authorization code has expired or has already been used.
Ensure your authorization codes are being used correctly and have not expired. Additionally, check if the refresh token has expired.

Error - unauthorized_client

This means the OAuth client (application) is not allowed to use the specific flow (e.g., authorization code, implicit, or client credentials).

Go to App Client Settings in the AWS Cognito console and confirm that the correct grant types are enabled, such as Authorization code grant, Implicit grant, etc., depending on your application’s flow.

Error - access_denied

This occurs when the user denies consent or the client app doesn’t have permission to request specific scopes.

Make sure the user has provided proper consent for the required scopes.
Also, ensure the requested scopes are available and authorized in the App Client Settings.
