[Samba] Cannot disable roaming profile in smb.conf

[Cesar Amaya]

Hello list,
I have a Samba-LDAP PDC and I cannot disable the roaming profile feature 
in trough my smb.conf file.
I am using the following software: FreeBSD 7.0 Release, samba-3.0.28,1, 
openldap-2.3.41 and smbldap-tools-0.9.4_2.

This is a bit of my smb.conf file:
[global]
workgroup = AMECC_SAL
enable privileges = yes
security = user
encrypt passwords = Yes
obey pam restrictions = No
ldap passwd sync = Yes
log level = 2
syslog = 0
logon script = logon.bat
logon drive = ""
logon home = ""
logon path = ""
domain logons = Yes
preferred master = yes
domain master = yes
local master = yes
wins support = yes
wins proxy = yes
dns proxy = no

Can anybody help me out here.
Thank you all!!!
