group permissions on directory being ignored for group member

[Itamar Gal]

Hey Patrick,

Thanks for your response.

Read this for starters, it should make more clear what is going on:

Thanks for the link. As it happens, I actually have that article bookmarked
from a couple of years ago; the web is a small place sometimes. Here's the
ACL for the directory in question:

$ getfacl /directory

getfacl: Removing leading '/' from absolute path names
# file: directory
# owner: root
# group: groupname
# flags: -s-
user::rwx
group::rwx
group:groupname:rwx
mask::rwx
other::---

Cheers,
Itamar
