[Samba] roaming profiles samba 4

[Trenta sis]

hi,

I'm evaluating to migrate our samba and ldap domain with samba 3 to samba 4
ad, and I have problem with roaming profile in samba 4.
I have configured with
https://wiki.samba.org/index.php/Implementing_roaming_profiles and for new
profiles created works perfect, but my problem is that I have many users to
migrate keeping profiles from samba 3 domain but our problem is that wiht
migrated profilesis not working, always loads a temporary profile and cifs
and security permissions are ok.

Permissions seems correct because from this user can acces to cifs share
and his folder, my problem is that I can't find any log or similar to find
where is the problem

Anybody can help?

thanks
