[Samba] samba pdc roaming profiles

[Καράμπης Παναγιώτης]

HEllo, i am running samba 3.0.14a with this smb.conf file:
[global]
netbios name = redhat
workgroup = net2day
server string = PDC [on Redhat :: Samba server %v]
security = user
encrypt passwords = yes
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
hosts allow = 192.168.0.0/24 127.0.0.1
interfaces = lo eth0
bind interfaces only = yes
local master = yes
os level = 65
domain master = yes
preferred master = yes
null passwords = no
hide unreadable = yes
hide dot files = yes
domain logons = yes
logon script = login.bat
logon path = \\%L\profiles\%U
logon drive = H:
logon home = \\%L\%U
wins support = yes
name resolve order = wins lmhosts hosts bcast
dns proxy = no
time server = yes
log file = /var/log/samba3/log.%m
max log size = 50
smb passwd file = /etc/samba/private/smbpasswd
add user script = /usr/sbin/useradd -m %u
delete user script = /usr/sbin/userdel =r %u
add group script = /usr/sbin/groupadd %g
delete group script = /usr/sbin/groupdel %g
add user to group script = /usr/sbin/usermod -G %g %u
add machine script = /usr/sbin/useradd -s /bin/false -d /dev/null %u
passwd program = /usr/bin/passwd %u
passwd chat = "*New password:*" %n\r "*New password (again):*" %n\r \ "*Password changed*"
unix charset = ISO8859-1
[netlogon]
path = /home/samba/netlogon
public = no
writeable = no
browseable = no
[profiles]
path = /home/samba/profiles
browseable = no writeable = yes
default case = lower
preserve case = no
short preserve case = no
case sensitive = no
hide files = /desktop.ini/ntuser.ini/NTUSER.*/
write list = @smbusers @root
create mode = 0600
directory mode = 0700
[homes]
path = /home/%U
browseable = no
valid users = %S
writable = yes
guest ok = no
inherit permissions = yes
[public]
comment = Public Stuff
path = /home/public
public = yes
writeable = no
browseable = yes
write list = @users

all work fine i have to admit. My question is: Is there any way to be a real time synchonization between the profiles?
To force windows not to copy the profile from server when the user logs in but use the one residing directly on the linux box.
