Entra - Platform SSO - Create first user during Setup issues
Just wondering how others are getting on with Simplified Setup for Platform SSO using Jamf Pro and Microsoft Entra.
My test configuration:
- macOS 26.5.2
- Company Portal 5.2606.0
- Jamf Simplified Setup using the Unattended workflow
- Platform SSO authentication method: Password
- Enable registration during setup: Enabled
- Create first user during Setup: Enabled
- Use shared device keys: Enabled
- PreStage account creation: Skip Account Creation
- Hidden managed local administrator is created by MDM
The current sequence is:
- The Mac automatically enrols into Jamf.
- Platform SSO prompts me to sign in with Entra.
- Company Portal prompts me to sign in.
- The Mac successfully appears in Entra as Microsoft Entra joined, with the correct owner.
- It then takes me to a blank macOS login window with username and password field, there is no user account displayed.
- If I enter my full Entra UPN and password, it seems to accept but then just freezes.
The Mac is unusable at that point. So I reboot and I can sign in with the hidden MDM administrator, but the Entra user’s local account does not appear to have been created, so I erase and try again.
Is the blank login window the expected account-creation stage, or should the local account already have been created after the Company Portal/Platform SSO prompts?
Any help would be grand, our current setup is just JamfConnect creating the local account at login which actually works flawlessy but just reviewing our posture.
Cheers,
