Ubuntu :: Samba Share With Group Permissions?
Nov 18, 2010
I am trying to set up a Samba share on one of my machines where I am the owner and a special group manages permissions for read-only access ( me:specialgroup ). If I log into the share as me, there is no problem (I have read/write privs as per usual). However, I am not able to log into the share using any of the group members (there is only one currently). That user is not able to access the share (failed to mount).
The folder (which is the share) is owned by me:specialgroup and the permissions have been forced down the folder. Samba is set to Share this folder with no guest or others write access.

I have a couple of user accounts where each member belongs to a group i have created: Each user access the share using their own user account credentials.
How can I configure Samba in a way so that each modification done on the share gets the owner of the user and my group instead of the user and the users own group? I would also like the access rights to be 770 to each modification.
In other words, today each modification by "userA" get the owner "userA.userA" and I would like it to be "userA.MyGroup" with "rwxrwx---" permissions.

I'm studying Linux and just started reading about permissions and ownership. My question is how would you have multiple users or groups given access to a certain directory? When doing an ls -l I see the owner, group and others that have permissions that have access to the file or directory. But what if I need multiple different groups access to a particular file or directory all with different permissions?

On our fileserver, we primary use samba to share files to our users, but a few users have to use ssh/sftp to access the file server. In samba we have the shares setup so that permissions are forced to be the correct group owner and group read/write. The problem is those few who access via ssh/sftp. There files do not have the correct permissions. These people are not the most computer savvy, I'm dealing with biologist here. Is there some way to fix this or will I just have to setup a cron job to go through and set permissions periodically?

This is a interesting confusing problem.Ok I have group with 3 users.I have a folder in /home with owner as root, and group that has read/write permissions.However if a user opens up a file and saves it via samba, the owner changes to the user, and the group members only have read permissions on the file.

Sorry if this is the wrong section for this type of question. Anyway, I have two servers running Ubuntu 10.04. Server A has an NFS share that is mounted on server B, and the former has this share set up with specific permissions for a group called netusers. This group basically grants its users read/write permissions, and blocking all of files from anyone who's not part of the group.My question is this: how can I set up the permissions on server B, such that if I was to add a new user on server B, he would have read/write access to the share? I tried adding a counterpart group called netusers with the same permissions on B, but that didn't work.

I have a user community of about 2000 users and a samba server running on AIX that currently hosts a read-only share for the whole company.
[Released]
path = /mypath
guest ok = Yes
But now I have been requested to make this share available as read-only for some users and completely inaccessible to everyone else. The number of users who will have access is probably a few hundred and I expect users to be added/removed on a daily basis. Some of the users have unix logins, while others do not. Because of this, I hesitate to mess with user mapping because I would have to manage this every day, unless I do something with a script.
Can someone suggest a scheme I can use to deny everyone except for certain users without having to use user mapping?Someone here in my office suggested we use hosts allow or deny, since the users who will still have access are located on the same subnet. However, there is a distinct possibility that a small number of people on a few other subnets will need access. Is there a way I can specify hosts allow but still allow specific users from other subnets?Forgive me if this question has been asked before. I'm sure it must have been, but I am having trouble doing a search of the archives that will give me advice about this particular problem.

The current situation:there is a samba PDC with ~50 XP workstations, all working fine for the last two years.The goal:Cycle older hardware back into production by installing ubuntu on them. These workstations must authenticate against the domain, and must automatically mount a public, a user, and a department share that contains folders with various group permissions.The added challenge:Since the office where this lan is located is closed for the next week or so, the ubuntu workstation I am testing with is connecting via a site-to-site VPN. This is soon to be mandated as a requirement anyway, so if not done now it will have to be done later anyway. I mention this since it *may* be something that could be interfering with the success of my mission, however, given what does work, I do not think this is my culprit.
What does work:Thanks to winbind, I can log into the ubuntu workstation via gdm with my domain credentials, and thanks to pam_mount my shares do mount correctly. I take this to mean my pam conf files are correct, along with nsswitch.conf.wbinfo -p, -a, -t, and -u work on the workstation. getent passwd returns DOMusers.listwbinfo -p, -t, -Y, -S, -G, -n, -s, etc, all work on the PDC. getent passwd returns a list from /etc/passwd and getent group returns a list from /etc/group.A remotely controlled windows workstation on the lan works as expected.
It appears that winbind is not able to parse the group permissions at all, not for the user, nor for the folders.The hope:is that someone can say that this problem of group permissions not being recognized has a typical cause (though several hours/days of google searching has revealed no such thing). However, I can provide a great deal of supporting information, as I have gone through documentation and testing extensively (though not extensively enough, apparently). For my own sanity, I put most things I tried into a text document so I could review it and look for errors in judgment, that doc ended up being some 1500 lines long, and doesn't include conf files. Rather than flooding this post, if someone is up for reviewing it, I can definitely make it and further supporting info available...

I have Ubuntu server 10.04 joined to a domain using Likewise Open. I can login using my domain credentials and have added my domain account to the sudoers file. Now that I've got it joined to the domain I want to add some samba shares and have domain members use their accounts to access them. However, no matter what combination of my domain name and the domain user or group I use in the valid users field it won't let me in. What's the proper way of inputting a domain user or group in the valid user field?
This is the entry I'm using for the share:
Code:
[testshare]
path = /srv/testshare
valid users = @"Domain Name+Domain Group" (Have tried many things here)
public = no
writable = yes
printable = no
create mask = 0765

i have an old desktop that i have decided to use as a central point for localhost/website files. I have 2 laptops, a ubuntu and vista, and i want them both to be able to see the public_html folder on my desktop, and be able to create/update folders and files.
I have set up the samba sharing and that's working fine, but when i create folders using my laptop, they are not writeable to the desktop or other laptop because my laptop is the creator. Is there a way that I can set it so that whenever folders/files are created from either laptop, they have full permissions?

When I create a new folder on my ubuntu machine and share it with my windows 7 machine using 'net usershare add <dir> <path>', I can't get write perms in Win 7. It keeps giving me a "You need permission to perform this action'. I've chmod the folder to 777 but still no luck.
The funny thing is, it was all working fine until I tried to add a new usershare yesterday (Can't think what I've changed). I use this sharing method to share all of my development /var/www/ folders so I can work on them from my win machine.
I have had a few problems with my samba smb.conf, and it nuked and rebuilt yesterday. I'm fairly new to the Linux game, and this permissions problem has me baffled.

what I am trying achieve is read/write access for my MS domain account and read-only access for everyone else. In smb.conf I have this:
Code:
map to guest = bad user
usershare allow guests = yes
username map = /etc/samba/smbusers
[code].....
I can access this fine with my MS domain account, what I can't work out is how to give others read-only access to the same share. I guess I could create a second share for the same folder with a different name and permissions, but that seems a bit clunky and I'd have to remember to pass on a different name to the one I am using. I also tried using the Nautilus right-click "Sharing options" and then setting the folder permissions. This works fine for giving others read-only access, but loses capitalisation of the share name and doesn't seem to recognise my MS domain account as being valid.

I'm trying to set up my samba server so that all the shares are visible to everybody but that some shares can only be accessed by certain users. I have a folder Video that everybody can access without a username or password. I now want to create a share that only I can access called webserver.
This is my samba.conf
Code:
[global]
dns proxy = No
netbios name = DATABOX
guest account = nobody
restrict anonymous = no
browseable = yes
server string = server
workgroup = WORKGROUP
public = yes
security = share
[Video]
Writeable = yes
Path = /media/data/Video
Public = yes
[webserver]
Writeable = yes
Public = no
User = malteser
Path = /media/data/Webserver
Windows does not let me enter a username or password. I'm pretty sure this used to work.

I have set up a computer to use as a file server using Samba. I attached a 1TB hard disk to it and had the system to mount it automatically. I have 4 user accounts which will be able to access this network share. An administrator account is called "server". I'll call them user1, user2 user4. This is the folder structure:
+-/mnt/FILES
+-BACKUP
backup files (accessible only to "server" user)
+-MUSIC
music1.mp3 (read only files for all users)
music2.mp3
[Code]...
I don't know which groups I should create. I'm having a hard time setting file/folder permissions. And I wanted to know how to set Samba so that it won't ask for a password when accessing public/group files, but asks for it when accessing private user files.

I have a samba shared folder in my flash disk. Yesterday I installed ubuntu 11.04 and now sharing is not working any more. I do the usual procedure (that worked so far), I right click my folder > sharing options and tick "share this folder" as well as "Allow others to create and delete files in this folder" but I dont get the usual messages asking to add permissions automatically.When I try to mount my folder in another pc with linux, I get permission denied and that the folder is only readable and in another, windows cannot find the network path to my folder.My folder has about 10.000 files. asking to add permissions automaticallyI created another folder on the same flash and when I create share I get the message asking to add permissions automatically but it is not visible either. I even cant see my folder in "my places" > network, so it is not a matter of the mounting command

Certain files are being created with ACL permissions attached. I am not sure why. Is there a smb.conf option that will stop this from happening?

I have set up a Samba share via my CentOS 5 server (the samba share is actually a mounted filesystem, not local machine space). I have been successful in adding permissions for my windows users within the smb.conf, but have an additional need that I cannot figure out. I would like for my Windows administrators to be able to create folders and assign permissions from their machines (and their Windows GUI). Ultimately I need the folders on the Samba share to behave correctly when Windows group permissions are applied by these administrators.
When the folders are created, the "Everyone" identity cannot be deleted and sometimes "Creator Owner" or "Creater Group" show up. I have seen several threads start down this path, but haven't seen a definite answer (I may have just missed it!).

My samba-shares are mounted in fstab. Everything works fine except for one small issue: when copying files from the local PC to the share the files are copied but the timestamps and permissions of the files are not. Instead a message "operation not permitted" appears. 'root' on the client can copy files WITH timestamp etc, a normal user cannot.
Below the line in fstab on the client and smb.conf on the server.

I've got my Samba shares up and running. I can stream files from the server, I can create files on the server, and I can copy files from the server.
Running a Windows program (from a Windows box) directly from the Samba server, however, is turning into a nightmare. I'm getting Access is Denied errors from the Windows box, yet I can copy/create/etc from the entire directory with no problems.
Are there any special permissions I need to run EXE files from a Windows box, located on a Samba share? I've already chmod'd everything to 777, and I show full access when ls -Z is used.

A bit of an oddity that I've recently run into with my storage folder in my system; it's a newly installed drive that I've set to mount at /storage. When I first tried to use it, programs that I used that attempted to write to it tossed Access Denied errors at me in their own way. Checking the permissions (at the Terminal, ls -l / | grep storage) showed that /storage was set to 'rwxrwxr--'--Owner and Group were given full read/write/execute, but Others could only read. However, my logon to my system is a member of group root. Why, then, with the above bits set, would I not be able to write to it? Changing Others permissions to rwx (and presumably rw would have worked out for me since I don't leave anything executable there) allowed me to write to it, but I don't understand why that would have been necessary. So far as I'm aware, the prior drive that was in my system--mounted at the same location--did not need this treatment.
