[Samba] file locking on linux samba with mac osx and windows have no function?

[Joris Heinrich]

hallo list,

I have the following problem:

smb.conf

[global]
         server string = file1.int.stayfriends.de
         unix extensions = No
         socket options = SO_KEEPALIVE TCP_NODELAY IPTOS_LOWDELAY
         dns proxy = No
         ldap ssl = no
         read only = No
         create mask = 0660
         directory mask = 0770
         #map hidden = Yes
         #map system = Yes

         # 3. Logging Options:

         log file = /var/log/samba/%m.log
         max log size = 50
         log level = 3

[cd-depart]
         comment = Allgemeine Daten Test Daten
         path = /test/cd-dpart/
         valid users = @smb-cd

mac osx and windows can access a file at the same time.

smbstatus:
