I have an on-premise deployment of Windows Hello for business [Certificate Trust] using ADFS 4.0 DRS. I also have an O365 Apps for Enterprise (Pro-plus) subscription. The identities (users only) are synced from on-premise to Azure AD. Only 8 attributes (Required for O365 Pro-plus is synced), [App Filtering in used]
accountEnabled cn displayName objectSID pwdLastSet samAccountName sourceAnchor usageLocation userPrincipalName
No device/group write-back is enabled, no other O365 applications are used.
I am seeing plenty of errors like ones mentioned in blog below (Q4) in Synchronization Service , where the service is trying to overwrite/remove the msds-keycredentialLink attribute [Populated to due WH4B provisoning] for insufficient permissions.
They should be triggered by the synchronization rules listed below
IN from AAD - User NGCKey (to DeviceKey in mv) Out to AD – User NGCKey (from DeviceKey in mv to msds-keycredentialLink in AD)
My questions,
Why does it need to writeback the NGCkey ?
Why the errors still persists even if the below rules are disabled ?
