[Samba] windows 7 roaming profiles

[steve]

Hi
Samba4 DC and win 7 clients.

The user profiles are stored in a profiles share:
[profiles]
     path = /home/CACTUS/profiles
     read only = No

This works OK and the user can logon to different boxes with the same 
profile. The profile folders such as Desktop, Downloads etc. however, 
also appear stored on the local disk under c:\users\username. Any file 
saved e.g. on the Desktop, is not saved to the roaming profile until the 
user logs off.

It seems pointless to have a roaming _and_ a local profile.

A few qns:
1. What am I doing wrong?
2. Is it correct that the profile files are not synced until the user 
logs off?
3. Unless /the profiles folder is world read/write, the user gets logged 
on with a temporary profile. Correct?

Thanks,
Steve
