hi
Without more specific information about the issue you are facing, it is difficult to determine where you may be going wrong. However, here are a few general tips that may help:
Make sure that you have followed all the steps in the blog post and the comments correctly, including registering the application in Azure Active Directory, configuring the app settings and web.config files, and enabling the OAuth 2.0 authentication provider in Business Central.
Double-check that the configuration settings match between Azure Active Directory and Business Central, especially the client ID and secret, redirect URI, and scope.
Check the Business Central event viewer for any error messages related to authentication or SSO, which may help identify the issue.
Make sure that the user account you are using to test SSO has the necessary permissions in both Azure Active Directory and Business Central.
If you are still having issues, try reaching out to Microsoft support or a Business Central expert for assistance in troubleshooting the issue.
