How do I mount a CIFS share via FSTAB and give full RW to Guest

I want to create a Public folder that has full RW access. The problem with my configuration is that Windows users have no issues as guests (they can RW and Delete), my Ubuntu client can't do the same. We can only write and read, but not create or delete.

Here is the my smb.conf from my server:

[global]    workgroup = WORKGROUP    netbios name = FILESERVER    server string = TurnKey FileServer    os level = 20    security = user    map to guest = Bad Password    passdb backend = tdbsam    null passwords = yes    admin users = root    encrypt passwords = true    obey pam restrictions = yes    pam password change = yes    unix password sync = yes    passwd program = /usr/bin/passwd %u    passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .    add user script = /usr/sbin/useradd -m '%u' -g users -G users    delete user script = /usr/sbin/userdel -r '%u'    add group script = /usr/sbin/groupadd '%g'    delete group script = /usr/sbin/groupdel '%g'    add user to group script = /usr/sbin/usermod -G '%g''%u'    guest account = nobody    syslog = 0    log file = /var/log/samba/samba.log    max log size = 1000    wins support = yes    dns proxy = no    socket options = TCP_NODELAY    panic action = /usr/share/samba/panic-action %d[homes]    comment = Home Directory    browseable = no    read only = no    valid users = %S[storage]    create mask = 0777    directory mask = 0777    browseable = yes    comment = Public Share    writeable = yes    public = yes    path = /srv/storage

The following FSTAB entry doesn't yield full R/W access to the share.

//192.168.0.5/storage /media/myname/TK-Public/ cifs rw 0 0

This doesn't work either

//192.168.0.5/storage /media/myname/TK-Public/ cifs rw,guest,iocharset=utf8,file_mode=0777,dir_mode=0777,noperm 0 0

Using the following location in Nemo/Nautilus w/o the Share being mounted does work:

smb://192.168.0.5/storage/

Extra info. I just noticed that if I copy a file to the share after mounting, my Ubuntu client immediately make "nobody" be the owner, and the group "no group" has read and write, with everyone else as read-only.

What am I doing wrong?
