Spring Boot using Azure OAuth2 - reply URL does not match error

Question

I have Spring Boot web application that I attempting to secure with Azure OAuth2. This application is based on the Azure SDK sample azure-spring-boot-sample-active-directory-webapp.

I build and deploy the application to Azure as a Web App. I am challenged for my MS Credentials, I give my consent to share my information. I get the following error:

AADSTS50011: The reply URL specified in the request does not match the reply URLs configured for the application: '**client id**'.

I am sure the issue is around the Registered Application's redirect urls. I register the urls the sample tells me to register, but I still get the error. I have deleted the Azure AD registered app and started over, no change in behavior.

I see this error with Edge and Chrome.

question from:https://stackoverflow.com/questions/66065527/spring-boot-using-azure-oauth2-reply-url-does-not-match-error

Answer 1

I had to add the following to my application.yaml.

server:
  forward-headers-strategy: native

By way of explanation

I turned on debugging on my application and I finally saw what was causing my issue:

Redirecting to 'https://login.microsoftonline.com/**tenant id**/oauth2/v2.0/authorize?response_type=code&client_id=**client id**&scope=https://manage.office.com/ServiceHealth.Read%20openid%20profile%20offline_access%20https://graph.microsoft.com/User.Read%20https://graph.microsoft.com/Directory.AccessAsUser.All%20https://graph.microsoft.com/Directory.Read.All%20https://manage.office.com/ActivityFeed.ReadDlp%20https://manage.office.com/ActivityFeed.Read&state=rccivv5nfrx270lpF_y4hHGDP-hhfUSSKI0mmokkNNA%3D&redirect_uri=http://myapp.azurewebsites.net/login/oauth2/code/azure&nonce=fVQX_yumChDneZJvE1pLljs81thZtpBk8do5h1XClGs'

The important part is the redirect_uri parameter: http://myapp.azurewebsites.net/login/oauth2/code/azure

My Spring Boot app was using http instead of https.

Now I found an article that addresses this issue where they fixed this same issue as I indicated above.
