samba - Jan 2016 - Cannot write to home directory, but I can write to subfolder

I have a storage server running samba 3.6.6 on Debian. Unfortunately I
cannot easily upgrade samba as this is a production server.  The server is
a member of a Samba-based domain, unix users are still handled by NIS.

When I logon to a Windows 7 pc (also part of the domain) with my own user
my homedirectory is automatically available as H:\. I can see the content
of the directory but when I try to write anything I get "You need
permission to perform this action".  On unix I have no problem creating
files in that same folder.  The same goes for any existing subdirectories.

I created a folder with 777 permissions. When I try to create a folder
inside that folder from Windows the action succeeds. When I look at the new
folder from unix the user and group are the same as the other folders,
permissions are set to 755. The only difference is that there is a default
ACL
    default:user::rwx
    default:group::rwx
    default:other::r-x
(which I do not like actually as this means that anything I create from
unix in that folder now gets default permission 775, ugh).
Setting that same ACL on my homedirectory doesn't change a thing, I am
still unable to create any files or folders in my homedirectory.  I am
however able to create files and folders in the subdirectory I created from
windows.

Fortunately most other users can create files in their homedirectories
without problems.

Any idea what could be causing this and how to resolve it?

Rebooting the server is not an option.

Hai Nico, 

Did your stop samba and start samba already. 
I have on one old server, also debian wheezy samba 3.6.6 about the same problem,
stopping samba and starting solves it.  !! restarting samba not !!
Give it a try. 

If that does not work, try the following. 
Disconnect all you netwerk shares on the computer and reconnect them. 
I have 1 pc here (win7 64bit) which is getting a "ghost" share. 
With that i mean one user gets a drivemapping to another users folder,
When this happens, we have also the problem that this user cannot open or write
any file.

So 2 thing you can tryout without rebooting the server. 


Greetz, 

Louis

Hi Louis,

I tried restarting samba on the server already.  I also tried rebooting the
client pc a number of times.  The folders are mounted via GPO's.  I assume
rebooting the pc should have the same effect as remounting the shares?

I also had a look at the permissions from Windows.  When I look at the
permissions of the new folder I managed to create I see there is a strange
user with only an SID, no username listed.  I seems I have some ghost users
on my system.  Not sure whether this is an issue on the domain side or on
the server.  I'll try rebooting my DC's again.

Nico
