[Samba] Automatic Group Shares

[Murray Trainer]

Hi All,

We use an automatic home share of the form below.

[homes]
        comment = User Home Dirs
        path = /home/%U
        valid users = %S
        read only = No
        create mask = 0777
        directory mask = 0777
        browseable = yes
        guest ok = no

Is it possible to do group shares a similar way?  We want to have an
automatic group share for any secondary groups with a name like share_*
and only allow the members of share_* access to it.  We want to avoid
having to manually add each share group to smb.conf and restart the smb
daemon each time we add a group of the form share_*.

Thanks

Murray
