@Onur Tanrıverdi, Thanks for posting in Q&A.
From your description, we understand that your organization is trying to automatically enroll device in Intune using user, but get errors due to the user not authenticating.
I did some research about the issue, here are the settings you can check:
- The user has already enrolled the maximum number of devices allowed in Intune.
- The device is blocked by the device type restrictions.
- The computer is running Windows 10 Home. However, enrolling in Intune or joining Azure Active Directory (Azure AD) is only supported on Windows 10 Pro and higher editions.
- The Azure AD setting Users may join devices to Azure AD is set to None, which prevents new users from joining their devices to Azure AD. Therefore Intune enrollment fails.
- We noticed that you already have Intune licenses, the auto-enroll also need Azure AD premium licenses, please check the Azure AD premium licenses are assign to users.
For more information about the issue, please visit the link below:

Moreover, if all above you check are fine and still get errors about enrollment, please go to device and check logs which locate in Event Viewer > Applications and Services logs > Microsoft > Windows > DeviceManagement-Enterprise-Diagnostics-Provider >Admin to see if there’s any related error.
If there is anything else, feel free to contact me.
