I have just tried to set permissions on folders present inside "profiles" share,
and there it works! I can add users, change permissions and so on.

The ownership of /usr/local/samba/var/profiles is also root:users with same rights as my /home/windows folder (which is "homes" share). So I don't get why I can set permissions and edit users in the profiles share, and not in the homes share.

/home is not on a separate partition, everything is on the same partition, so not a filesystem issue.
hope it can help to pinpoint the issue...

Hi, this is my first message here. I need help, the reason is in the title.
The version running is SAMBA_4.0.0ALPHA18_DEVELOPERBUILD

It was running just fine until I had (for some reason) had to transfer all
the system (ubuntu 11.10 server)
to another clean hard drive. I used  "rsync -rltgoHDv /olddriveroot
/newdriveroot" to copy the files,
and installed grub on the new disk.

Now the problem is that  samba4 works, domain users can log on and access
files, but the permissions
have been reset to some basic values (different from all the ones I had set
before), and I can not
change them at all from a windows7 box as I could before. When I apply the
changes, it takes a while
to process the files, then the "basic" permissions are set again (my changes
lost).

Here is my /usr/local/samba/etc/smb.conf :


[global]
         interfaces = 127.0.0.1/8 192.168.1.0/24
         server role = domain controller
         workgroup = ACEIUBUNTU
         realm = ACEI2
         netbios name = ubuntuserveur
         passdb backend = samba4
         security = ADS
         domain master = yes
         local master = yes
         wins support = yes
         browseable = yes
         log file = /var/log/samba/smbd.log
         socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE
SO_RCVBUF=4096 SO_SNDBUF=4096

[netlogon]
         path = /usr/local/samba/var/locks/sysvol/acei2/scripts
         read only = no

[sysvol]
         path = /usr/local/samba/var/locks/sysvol
         read only = no

[profiles]
         path = /usr/local/samba/var/profiles
         read only = no

[homes]
         path = /home/windows
         read only = no

-------------------------------------------------------------------------

The AD database is readable, since I can edit users and computers with the
administration toolkit
from windows7 box.

/usr/local/samba/bin/testparm gives the following result :

Load smb config files from /usr/local/samba/etc/smb.conf

         path = /usr/local/samba/var/locks/sysvol/acei2/scripts
         read only = No

[sysvol]
         path = /usr/local/samba/var/locks/sysvol
         read only = No

[profiles]
         path = /usr/local/samba/var/profiles
         read only = No

[homes]
         path = /home/windows
         read only = No
------------------------------------------------------------------------------------

Also, user_xattr and acl are enabled on the ext4 file system, and the home
folder on which I can
not set permission has root:users ownership with rwx rights (which was
working before).

Since it is a recopy from a working system, maybe there is a problem with
some file permission
on the linux system, but I have searched a lot without finding any solution.
Any help would be
greatly appreciated.

Regards,
micmac
