[Samba] disable roaming profiles

[Miguel Angel Miranda]

Hi, i followed the official faq trying to disable roaming profiles but
it doesnt work

in smd.conf i have

logon home = 
logon path = 

for every new pc that i have joined to the domain, the hole desktop and
mydocs directory is transfered to the server!!!!!!!
i have wasted 15G because of that and if a user logons in another
machine all the crap is transfered back again in this pc.
So, it is not working, am i missing something here?

i have this lines too:

[profiles]
   path = /opt/samba/profiles
   writeable = yes
   browseable = no
   #create mode = 0644
   #directory mode = 0755
   # this prevents users from browsing other peoples' profiles
   create mode = 0600
   directory mode = 0700


Are the above lines necesary?, may they are enabling the profiles again?
any advice will be greatly appreciated.
thanks
