[Samba] gpo not working with samba 4 migrated

[Trenta sis]

Hi,

I have migrated samba 3 domain to samba, and I have found that when you try
to use gpo this are not applied we receive in windwos event log errors with
permissions in sysvol, I have checked paths to sysvol gpos and are correct.
Also I have tried with a new fresh domain (not migrated) and with this new
install works GPO


How can I debug this problems and find a solution?

Thanks
