Issue with Redirect URL Truncation in Entra ID After Authentication

Question

After successful authentication, the redirect URL I provided in the app registration authentication section is not returned completely.

For example, in Entra ID, I provided the redirect URL as https://localhost/auth, but Entra ID returned the URL as https://localhost, truncating the /auth part from the provided URL.

Hi @K Nadeem , this might be caused by a mismatch between the redirect URI configured in your app registration and the redirect URI specified in your authentication request. Please try the following for me:

1. Check the redirect URI configured in your app registration in Entra ID. Make sure that it matches the redirect URI specified in your authentication request.
2. Check the redirect URI specified in your authentication request. Make sure that it matches the redirect URI configured in your app registration in Entra ID.
3. If the redirect URIs match, try adding a trailing slash (/) to the redirect URI in your app registration and authentication request. This can sometimes resolve issues with URL truncation.
4. If none of the above steps resolve the issue, try using a different redirect URI in your app registration and authentication request. Make sure that the redirect URI is a valid URL and does not contain any special characters.

Please let me know if you have any questions and I can help you further.
