[Samba] Scenario with CIFS

[Alumno Etsii]

Hi all!

I'm trying to get samba working with CIFS, mounting a share on a client and
keeping the original file/dir permissions. The problem is that after I
(successfully) mount that share by CIFS, I can't write anything in it,
because I get a 'Permission denied' error. smbd version is 6.3.6.

My testparm is:

root@samba:~# testparm
Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)
Processing section "[shared]"
Loaded services file OK.
Server role: ROLE_STANDALONE

[global]
workgroup = SMB
server string = %h server (Samba, Ubuntu)
map to guest = Bad User
obey pam restrictions = Yes
pam password change = Yes
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n
*Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
unix password sync = Yes
syslog = 0
log file = /var/log/samba/log.%m

show add printer wizard = No
dns proxy = No
panic action = /usr/share/samba/panic-action %d
idmap config * : backend = tdb
hosts allow = 127.0.0.1, 192.168.0.
hosts deny = 0.0.0.0/0
printing = bsd
print command = lpr -r -P'%p' %s
lpq command = lpq -P'%p'
lprm command = lprm -P'%p' %j

[shared]
comment = Shared documents
path = /shared
valid users = myuser
admin users = admin
read only = No
create mask = 0700
force create mode = 0700
directory mask = 0700
browseable = No

///

Mounting command is:
# mount -t cifs //192.168.0.99/shared ./mount -o
uid=localuser,gid=localuser,iocharset=utf8,credentials=/tmp/credentials,nosetuids,noperm

File /tmp/credentials contains username myuser and its password.

I successfully mount that share, I can list, cd, etc. but not write:

root@monitor:/mnt/mount/archiveupload# ll
total 40
drwxrwxr-x 4 localuser localuser 0 oct 29 21:25 ./
drwxr-xr-x 3 localuser localuser 0 oct 29 17:30 ../

-rw-rw-r-- 1 localuser localuser 11 may 21 2009 VERSION
root@monitor:/mnt/mount/archiveupload# touch a
touch: no se puede efectuar `touch' sobre «a»: Permiso denegado

'localuser' exists in both server and client. My goal is to make that any
newly created file gets server's 'localuser' permissions. I added a
'smbpasswd -a' for myuser. I wonder why can't I write on this share from
the client, since I think permissions and mount options are ok.

I'll be very grateful for any idea!

Regards.

Then that won't work. You're connecting to the share as "myuser". Any
files you create will be created as "myuser", not "localuser".

Ok, so the file isn't created at all when you "touch"?

Does "myuser" have permission to write to /shared on the server?
