[Samba] OS X Clients Can't Create Sub-Directories

[Kimball Larsen]

I'm running samba on a local linux server, with a bunch of shares.  Over the last several years, this has worked perfectly in our heterogenous network of OS X and Windows.  All my windows clients still work perfectly - my users can mount the samba shares and create, rename, move etc files and folders. 

However, recently (starting yesterday) my OS X clients are unable to rename any sub directories on any of my shares. 

So, if I have a structure like this: 

Share Root
	FooFolder
		Bar Folder

My OS X users are able to create and rename directories in the share root, but are unable to rename folders they create in sub directories.

So, if my OS X user navigates to FooFolder and tries to create a new folder there, a new folder is created called "untitled folder", but I'm unable to rename it.  Every time I do, the finder says "You don't have permission to rename the item "untitled folder".

But, again, I can create and rename folders in the root of the share without issue. 

Here are the relevant bits from my smb.conf (Neighborhood is the name of the share):

[global]
        log file = /var/log/samba/log.%m
        load printers = no 
        guest account = nobody
        passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully* .
        socket options = TCP_NODELAY
        obey pam restrictions = yes
        encrypt passwords = true
        passwd program = /usr/bin/passwd %u
        passdb backend = tdbsam
        dns proxy = no
        delete readonly = yes
        server string = %h server
        invalid users = root
        workgroup = lappygroup
        security = share
        syslog = 0
        panic action = /usr/share/samba/panic-action %d
        max log size = 1000
        unix extensions = no


[Neighborhood]
  comment = Who are the people in your neighborhood...
  path = /mnt/brick/Neighborhood
  public = yes
  writable = yes
  create mask = 0777
  directory mask = 0777
  force user = nobody
  force group = nogroup


And here are the permissions on the root of the share:
root at jake:/mnt/brick# ls -la | grep Neighborhood
drwxrwxrwx 46 nobody nogroup 2360 2010-02-02 15:31 Neighborhood

And the "Advertising" directory where I want to create a sub directory.
root at jake:/mnt/brick/Neighborhood# ls -la | grep Advertising
drwxrwxrwx  4 nobody nogroup       144 2010-02-02 15:49 Advertising

And the resulting "untitled folder" that is created by the OS X client. 
root at jake:/mnt/brick/Neighborhood/Advertising# ls -la
total 11
drwxrwxrwx  4 nobody nogroup  144 2010-02-02 15:49 .
drwxrwxrwx 46 nobody nogroup 2360 2010-02-02 15:31 ..
-rwxrwxrwx  1 nobody nogroup 6148 2009-05-04 10:03 .DS_Store
drwxrwxrwx  3 nobody nogroup 1064 2008-12-17 15:38 Lead Tracking
drwxrwxrwx  2 nobody nogroup   48 2010-02-02 15:49 untitled folder


What should I be checking?

Thanks!
