Hi @bartek1234
Thank you for posting this in Microsoft Q&A.
I understand that you want to configure the application Single sign-on (SSO) and User Provisioning.
The error message indicates that automatic provisioning is not available for OIDC-based applications. To enable provisioning, you must either publish the application or create a non-gallery application.
Yes, it's possible to configure the application SSO and User Provisioning without publishing application in the Entra Gallery.
Create an Enterprise application in your tenant. Follow the below steps
- Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.
- Browse to Identity > Applications > Enterprise applications > All applications.
- Select New application > Create your own application > Select Integrate any other application you don't find in the gallery (non-gallery) option > Create
- You can be able to configure SSO and Provisioning.
Hope this helps. Do let us know if you any further queries.
Thanks,
Navya.
