samba - Mar 2003 - Old bug resurfacing?

I found this in the archives:
http://samba.cadcamlab.org/lists/samba/Feb2002/00318.html

It pertains pretty directly to the problem I'm seeing.
I first started having it with my 2.7 installed version
so I upgraded to 2.8.  I'm still having the same problem.

Basically, I have a group of web developers that use
the linux/samba server for editing files for the site.
All the files are "owned" by root.  The groups vary
based on the developers with access, and the files have
664 permissions.  (Directories have 2664

[www]
   path = /path/to/www
   public = yes
   writable = yes
   write list = @developers
   force create mode = 0664
   force directory mode = 2775
   printable = no

Everything was working great until a few days ago
(while I was on vacation - of course) one of them 
discovered that they couldn't overwrite files in 
a particular subfolder.  I've been racking my brains
trying to figure it out.  Nothing shows up in the
logs, and if I go up a folder everything works fine.

All the folder perms are good, and the file perms
are good.  And the perms of our local copies aren't
actually denying it, and the files are not in use.

If I copy the files using the same user(s) via ssh
everything works just dandy.  Has the same bug 
cropped up again or is this something different?

Never mind.  I do believe I found it, and it's not a
samba issue at all.  The users I was testing it with
were all in more than 32 groups, and the group perms
required to write to the file were post-32 in the list.

Creating a new user with just the one group works fine,
so I guess I'm looking at a glibc rebuild to increase my
NGROUPS_MAX setting.

Thanks anyway

It has. Google the specific links
on the subject of "reiserfs acl".

In a nutshell: You need to build your
kernel with ACL support. Or install it
out of your distro's depot (SuSE did a
good job of it). The reiserfs is then
ACL-compliant (mount with "-o acl,...").
