[Samba] Samba 4 windows 7 roaming profile not saved

[steve]

Hi
Version 4.0.0alpha18-GIT-bfc7481
In smb.conf I have:
[profiles]
         path = /usr/local/samba/var/profiles
         read only = no
The profiles are set to \\DOMAIN\profiles\%USERNAME% using dsa.msc

When a user first logs on, there is a message:

  'You cannot access your files and files created in this profile will 
be deleted when you log off. To fix this, log off and try logging on 
later.'

Logging back on again gives the same error.

I can work around this by manually creating the folder:

/usr/local/samba/var/profiles/user.V2

and changing uid:gid to whatever wbinfo -i user gives, after which the 
profile is saved OK when the user logs off.

I have looked using regedit to see if there were any bak profiles and in 
C:\Users to see if there was anything pertaining to the user but nothing.

The permissions on /usr/local/samba/var/profiles are:

drwxr-xr-x  6 root root  4096 Dec 30 16:31 profiles

Any ideas anyone?

Thanks,
Steve
