Hmm, you trust a Windows book more than the default configuration file,
which should give you many more, and better hints, than an outdated

Are you running winbind? If so, then, you (with the absence of 'winbind
use default domain = yes') should have groups named something like
MARTIN\branch99 (you an check with 'wbinfo -g'), so your 'valid users'
line should be something like:
valid users = @"MARTIN\branch99"
(the quotes may not be necessary in this case, but for other Windows
groups they may be).

Without seeing your share definition and/or the permissions of the
directory in question, it's difficult to postulate.
But, in general, here is some advice:
1)Whenever possible, use the filesystem to store access controls, rather
than configuration files. Next month you may give a user ssh access, and
then they may have greater or lesser access to the files than you
allowed with samba. If you use the filesystem permissions, they will be
Mandrake supports Posix-ACLs (not quite NT ACLs, but good enough for
most applications) on XFS (and has since Mandrake 8.1).
2)Please have a look at the default smb.conf (or maybe you still have an
intact /etc/samba/smb-winbind.conf to peruse), it would probably have
saved you a lot of hassle (IMHO).
3)You can setup winbind authentication during installation (at least for
Windows NT domains), which should do most things quite well for you.
