[Samba] Cannot write to home directory, but I can write to subfolder

Thu Jan 21 10:45:20 UTC 2016

O..k.... well done.  :-)  but risky but he it worked.. one reason why im using debian, easy upgrading.  :-)  

Its a strang bug in 3.6.6 which i havent identified and since this samba is so old, im just restarting for now. 

2 servers to go and im out of 3.6...  finaly... 

Greetz,

Upgraded my Debian Wheezy server to Samba 4.1.17 via wheezy-backports.  The users hardly noticed a thing and now everything works. I'm impressed.

In case you need to do anything similar:

   echo "deb http://http.debian.net/debian wheezy-backports main" > /etc/apt/sources.list.d/wheezy-backports.list

   apt-get update

   apt-get -t wheezy-backports install samba
   /etc/init.d/samba restart        (not sure this step is really necessary as the upgrade probably already does that)

Done

I tried the following:

* rebooted both Samba DC's   -- no change

* restarted samba on storage server -- no change

* remove client pc from domain, tried accessing the folder from non-domain pc -- no change

* created a temporary server (running samba 4.x) to serve the same homedirectores -- no problem at all

So that narrows the problem down to something on the storage server.  I'll try readding the server to the domain. Hopefully nobody will notice (most of my users are linux based anyway except for sales and management)

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.

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.
