[Samba] Everyone group difference between ACL/no ACLs.

Hello!

I'm running Samba 2.2.8a on top of a ext3 filesystem with ACLs enabled.
(kernel 2.4.20-gentoo-r2)

With ACLs disabled (i.e., mount /dev/hdd1 /mnt/floppy (no -o ACL)), the
Security box under windows 2000 works like I want it to with respect to the
Everyone group; If I want the Linux permissions to be, say, 770 (rwxrwx---),
I can select everyone and hit "Remove." The everyone group goes away, and
the Linux world permissions are set to --- or 0. This is what a Windows
administrator would expect, and group with no permissions doesn't appear in
the dialog. This also works for the Linux primary group.

However, if I enable ACLs (i.e., mount /dev/hdd1 /mnt/floppy -o ACL), then
the Security box works like it did with Samba 2.2.5 - the "Remove" button
does nothing. The everyone group pops right back up. I've done a debug level
10 dump, but it's all Greek to me (included below). If I try to remove the
primary group, the same symptoms occur.

If I manually (though Linux) change the permissions to 770, then the
Everyone group will not appear in the Security dialog.

Am I missing a simple config option?

Thank you!

smb.conf follows:

[global]
   workgroup = dorm
   netbios name = mp3box
   server string = Big Bad Music
   printcap name = lpstat
   load printers = no
   printing = cups
   log file = /var/log/samba/log.%m
   max log size = 50
   guest account = nobody
   security = share
   encrypt passwords = yes
   smb passwd file = /etc/samba/private/smbpasswd
   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
   wins support = yes
[share1]
   comment = share1
   path = /mnt/floppy/share1
   read only = no
   guest ok = no
   write list = bombcar, tdickson
   admin users = bombcar
   inherit acls = yes

log follows (logged into smbd as user bombcar which = root)
