[Samba] Roaming profils cannot sync four files

[Michael Funke]

Hello,

I'm using a WIndows Server 2016 as a DC and Samba 4.5 (Debian Stretch) as a
fileserver. The fileserver is made with Windows ACLs (exactly like the
Samba tutorial).
The Windows 10 Client cannot copy these 4 files:

C:\Users\testuser\AppData\Local\Microsoft\Windows\UPPS\UPPS.bin ->
UNC\FS\profiles\testuser.V6\AppData\Local\Microsoft\Windows\UPPS\UPPS.bin

C:\Users\testuser\AppData\Local\Microsoft\WindowsApps\Microsoft.MicrosoftEdge_8wekyb3d8bbwe\MicrosoftEdge.exe
->
UNC\FS\profiles\testuser.V6\AppData\Local\Microsoft\WindowsApps\Microsoft.MicrosoftEdge_8wekyb3d8bbwe\MicrosoftEdge.exe

C:\Users\testuser\AppData\Local\Microsoft\WindowsApps\MicrosoftEdge.exe ->
UNC\FS\profiles\testuser.V6\AppData\Local\Microsoft\WindowsApps\MicrosoftEdge.exe

UNC\FS\profiles\testuser.V6\AppData\Local\GroupPolicy\DataStore\0 ->
C:\Users\testuser\AppData\Local\GroupPolicy\DataStore\0

I'm actually not sure, if it's a samba-problem or not, but everything else
works fine.

What could be wrong?
