I have been using a lightly modified version of the perl logon
script in the samba contrib directory. Perhaps it can help you
with that.

The advantage of this script is that the secondary unix groups 
are automatically mapped to windows units (M:, J:, ...) based 
in their membership to those unix groups.

For you case simply add %m to the list of netlogon parameters
and write the desired configuration.

regards,

smb.conf:
=========
[global]
logon script = %U.bat

[netlogon]
...
root preexec = " /usr/local/bin/logon.pl %U %G %L"

	/----/

logon.pl:
=========
#!/usr/bin/perl
$usuario = $ARGV[0] ;
$grupoPrimario = $ARGV[1] ;
$servidor = $ARGV[2] ;

# log login activity
($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(time);
open LOG, ">>/var/log/samba/netlogon.log";
print LOG "$year/$mon/$mday $hour:$min:$sec";
print LOG " - User $ARGV[0] logged into $ARGV[1]\n";
close LOG;

# check the presence of a home directory
$idnum = (getpwnam ($usuario))[2];
$gidnum = (getpwnam ($usuario))[3];
$homedir = (getpwnam ($usuario))[7];
if ( ! -d $homedir) {
    mkdir(${homedir},0700) || die "No pude crear $homedir: $!";
    chown($idnum , $gidnum , ${homedir} );
}

# Start generating logon script
open LOGON, ">/var/lib/samba/netlogon/${usuario.bat}";
print LOGON "\@ECHO OFF\r\n";

# generic stuff.
print LOGON "NET USE /persistent:no\r\n";
print LOGON "NET TIME \\\\$servidor /set /yes \r\n";
print LOGON "NET USE U: /HOME \r\n";
print LOGON "NET USE F: \\\\$servidor\\publico   \r\n";


# specific user maps
if ($usuario eq "jefazo")
{
        print LOGON "NET USE z: \\\\$servidor\\CEO\r\n";
}

# primary group maps
if ($grupoPrimario eq "informatic") {
     print LOGON "NET USE H: \\\\$servidor\\$grupoPrimario  \r\n";
}

# secondary group maps
while (($grupoSecundario, $passwd, $gid, $members) = getgrent) {
    if ( grep /\b$ARGV[0]\b/, $members )
    {
        if ( $grupoSecundario eq "telefonia" ) {
            print LOGON "NET USE N: \\\\$servidor\\$grupoSecundario  \r\n";
        }
    }
}
close LOGON;
