Posted on by LN-26111544-0

Hello everyone,

i have a Problem with the Entra Connection in Business Central 22 (CU0) OnPrem.

My goal is to setup the current User Mail-Setup.

I have created an App registration in the cloud and startet the assisted Setup in the OnPrem System.

First i got the error aadstS50011 redirect URL missmatch.

I have no clue, where i can change the URL on the OnPrem Service Tier!

It was an old NST without SSL, so i need to edit the onPrem URL.

After that i deleted my app Registration and created a new one.

If i am going to start the assisted setup "Set up your Azure Active Directory accounts" again, i can insert the new app registration, but in the Mail-Setup the system is trying to connect to the old client id with Error: AADSTS700016: Application with identifier 'Old Client ID' was not found in the directory.. . How can i change those parameters in my OnPrem System?

Best regards

Louis

Hey guys,

thanks for your replies. Non of those answer my question.

Ive looked in the eventviewer on the NST Server and got the following error:

Message The server did not return any auth endpoint.
Category: AL Url Helper

I think it is, because he is trying to reach the wrong appId and get no response...

Some Backround about my Setup:
- One US Database
- 2 Service Tiers
- SSL with self signed cert
- new app registration (multitenant)
- windows auth
- public webbase url set

Ive opened the Azure AD App Setup Table 6300 directly, there are the new appid and the new redirect Url.

In the URL to azure auth, are the old ones:

I think ive got a workaround to this topic.

The Mandatory fields are in Table 4509 - Email - Outlook API Setup!

To restart the setup

My Solution is to deinstall "Email - Outlook REST API" and delete all appdata! Then reinstall and restart the assisted Setup.

What is the more elegant/official way, to enter and edit the Setup table?

Best regards,

Louis
