Hello list,

I'm having a "fun" time trying to figure out my ACL problems.
I've gone through the default ACL settings and the mask settings on
the filesystem to ensure that the user I am using does indeed have
access to the filesystem that is being shared out.
My issue is that I am unable to overwrite a file that already exists
with another file of the same name. I get the windows dialog "Are you
sure you want to overwrite this file" but when selecting "yes" it
fails with a big fat "The request is not supported". I can
edit/rename/delete this file so I think I have the right ACLs on the
folder it is in and on the file itself.

Here is the ACL on the folder that contains the file:
~ getfacl test
# file: test
# owner: root
# group: root
user::rwx
group::r-x
group:DOMAIN\134domain\040admins:rwx
mask::rwx
other::r-x
default:user::rwx
default:group::r-x
default:group:DOMAIN\134domain\040admins:rwx
default:mask::rwx
default:other::r-x

And here is the ACL on the actual file:
~ getfacl New\ Text\ Document.txt
# file: New\040Text\040Document.txt
# owner: DOMAIN\134Myuser
# group: DOMAIN\134domain\040users
user::rwx
group::r-x
group:DOMAIN\134domain\040admins:rwx
mask::rwx
other::r--

Here is the output from the logfile when I click yes to the dialog to
overwrite the file:

I should also note that if I try to overwrite a folder with a folder
of the same name instead of a file with a file of the same name, it is
successful.

Any help would be greatly appreciated.

Thanks,

Bigbeer
