[Samba] Can't write to samba director with windows 7

[Muhammad Anis]

Hi all,
I have a problem with using samba 3.5 with windows 7,
I had succeed in joining to samba domain, but when i log in with ldap
backend,
i can't write the directory from samba.
Here is the snippet of my smb.conf
[snip]
#logon drive
logon drive = M:
# logon home = \\%L\%U
logon path = \\%L\profiles\%U
# logon script = logon.bat

#Windows 7 compability setting
server signing = disabled
client lanman auth = yes
client ntlmv2 auth = yes
lanman auth = no
ntlm auth = yes

[homes]
        comment = home
        path = /home/%U
        valid users = %S
        browseable = yes
        writeable = yes
        create mask = 0600
        directory mask = 0700
[netlogon]
        comment = Network Logon Service
        path = /var/lib/samba/netlogon
        guest ok = yes
        writeable = no
        share modes = no

[profiles]
        path = /home/%U/user_profile
        read only = no
        # path = /var/lib/samba/profiles
        writeable= yes
        browseable = yes
        guest ok = no:
        printable = no
        create mode = 0600
        #directory mask = 0777
        directory mode = 0700

[/snip]

so, the problem is , i can log in with user from ldap, but i can't write the
profiles folder nor home folder
even when i change the folder permission to 777,
thank you,,
