Understanding the AADSTS500113 Error
The AADSTS500113 error is triggered when Azure AD cannot find a reply URL for the application. A reply URL, also known as a redirect URI, is where users are redirected after they have successfully authenticated with Azure AD. The reply URL is essential because it ensures a secure flow of tokens between your application and Azure AD.
To fix the AADSTS500113 error, you need to add or update the reply URL of your application in the Azure AD app registration settings.
Step-by-Step Guide to Fixing the Error
Step 1: Log in to Azure Portal
Log in to the Azure Portal using your Microsoft account credentials.
Step 2: Navigate to App Registrations
- In the left-hand menu, click on "Azure Active Directory."
- In the "Manage" section, click on "App registrations."
Step 3: Select Your Application
On the "App registrations" page, find and select your application from the list.
Step 4: Add or Update the Reply URL
- In the application's settings, click on "Authentication" in the left-hand menu.
- In the "Redirect URIs" section, click on "Add a platform."
- Choose the appropriate platform for your application (Web, Mobile and desktop applications, or Single-page application).
- Add the correct reply URL for your application. This URL should be the location where users will be redirected after authentication. For example, if you are building a web application, the reply URL might be
https://yourdomain.com/auth/callback. - Click on "Configure" to save your changes.
After completing these steps, the AADSTS500113 error should be resolved. If you still encounter issues, double-check the reply URL and ensure it matches the expected format for your application type.
FAQ
What is a reply URL (redirect URI)?
A reply URL, also known as a redirect URI, is the location where users are redirected after they have successfully authenticated with Azure AD. The URL is essential because it ensures a secure flow of tokens between your application and Azure AD.
How do I find the correct reply URL for my application?
The correct reply URL depends on the type of application and its configuration. Generally, the reply URL should point to a location in your application where authentication tokens can be processed and user sessions can be established. Check your application's documentation for specific guidance on determining the correct reply URL.
Can I have multiple reply URLs for my application?
Yes, you can add multiple reply URLs for your application in the Azure AD app registration settings. This can be useful if your application has different environments (e.g., development, staging, and production) or supports multiple authentication flows.
Why am I still getting the AADSTS500113 error after adding a reply URL?
Ensure that you have entered the correct reply URL and that it matches the expected format for your application type. If you still encounter issues, double-check your application's configuration and ensure it is correctly set up to handle authentication tokens from Azure AD.
Can I use a wildcard in the reply URL?
No, using a wildcard in the reply URL is not recommended because it can expose your application to security risks. Instead, specify the exact reply URLs for your application to ensure a secure flow of tokens between your application and Azure AD.
