I am having a problem when I try to rename or delete files. Most of our access to the server is through Samba. However, I tried rm and mv in linux and the problem is still there.

All our users are in the group associated with these files.
Permission for the files is 777.
lsattr shows no attributes.
The owner of the file and root can mv and rm.
Any other users cannot even though they they are in the same group.

The mv command results in the following messages.
mv: cannot unlink `ACH99': Operation not permitted
mv: cannot remove `ACH99': Operation not permitted

We have been running on linux/samba for over a month. I think we this problem just started in the last day or two. I am sure we would have noticed it earlier if it had been happening the whole time. I think I have only touched the smb.conf recently. None of this makes sense to me.

Help!

Please try not to double post. Thanks. This one is being closed, no need for two of the same.
