Samba Server Not Inheriting Permissions

I have setup a Samba server with about 6 users. My issue is that all of my users can only edit their own files. Even if I manually change the permissions on the parent directory new files are created with the specific user as the owner and the only person that can make changes to the file. I have several user who need to be able to edit the same files. Attached is my smb.conf

Hello,

Try adding this to your shares:
    create mask = 0770

For the above to work, the all users must have the same login group in your linux box.

For explanation about the latter you can check on the manual page of useradd and usermod.

I have added the create mask but it doesnt appear to be doing anyting. The owner is still changing and other people still cant edit files.
Hello nlhess2003,

Can you post the result of the command 'ls -al' from one of the shared folders please.
Command output of "ls -al /home/corpfiles/"

That looks like it helped with the permissions issue. Now I am randomly getting a new error that files are locked for editing by "another user" I have double checked and the user opening the file is the only one on the system. Doesnt matter if I try to open it as the creating user or another user. Any idea?
With what software does this usually happen?
The error is coming up in word, excel, and powerpoint
Happens to us with Excel too.

You should probably try changing oplock settings.

We usually include this in the global section, but can also be applied on a per-share basis:
    veto oplock files = /*.xls/*.XLS/*.xlt/*.XLT/*.dbf/*.DBF/*.ntx/*.NTX/

It is also passible to disable oplocks totally or on a share:
    oplocks = false
    level2 oplocks = false
We are still running in to issues. We narrowed it down to all new office documents .xlsx, docx, and pptx. They all come up saying "File In Use... Locked for editing by 'another users'. I have added the extensions in the veto oplocks thing and added the totally disable setting directly to my shares. Still not luck getting in to these files as the owner.
Try this in your shares please:
    posix locking = no

I do hope it works.
Same issue. Still saying they are locked. I am attaching new Samba file to make sure I have everything added correctly. [corpfiles] is the share I am currently working with.

Hello nlhess2003,

What distro do you use?
CentOS Linux 5.6, Samba version 3.0.33-3.29.el5_5.1  
Hello nlhess2003,

Apologies for the late reply.

We use the same distro for a few years now. Will first try to find users who use those files. Will get back to you as soon as I can.
The solutions partially works. Does not fully fix the issue.
