[Samba] Problem with NTConfig.POL+SAMBA+LDAP

[Mike]

Hello,

I installed two debian sarge servers with the following services: OPENLDAP, SAMBA 3.0, HEARTBEAT and DRBD. I used debian packages.
The RAID over IP is used for the /data and /home partitions.

I created a NTConfig.POL for my domain workstations and put it in /home/samba/netlogon.
But when  a user log on a machine, the policy is not applied.

For details:

# l /home/samba/
total 4
drwxrwxr-x  2 root root 4096 2006-01-25 14:31 netlogon
drwxrwxrwt  8 root root   98 2006-01-25 13:15 profiles

# l /home/samba/netlogon/N*
-rw-r-xr-x  1 root root 262144 2006-01-25 11:33 /home/samba/netlogon/NTConfig.POL

#vi /etc/samba/smb.conf
[...]
[netlogon]
   comment = Network Logon Service
   path = /home/samba/netlogon
   browseable = No
   guest ok = yes
   valid users = %U
   read only = yes

Do you have an idea?
Let me know if you need more informations...

Thanks a lot,

Mike
