Hello Friend

Excuse me, I was on vacation. I will answer your questions:

Where have you got to setting up your TurnKey Fileserver?
On a physical pc.

Also, just to be sure that we're on the same page, I assume that you're referring to access via SMB (i.e. Windows/Samba file sharing)?
Yes,  I want my users with windows access a folder shared by department (I.e. sales can access just sales folder and not other, accounting access to their own folder shared and so on)

Actually I just noticed that you've tagged "samba" and "shares", so I'm 99% sure I'm right. If not, please specify which protocol(s) you are planning to use.
I am not sure about what protocol, I think the common on my LAN network TCP/IP v4

Do you already have the users and groups on the server?
No i do not know how it works

Or did you need a hand with that too? (FWIW on our Fileserver appliance, we use legacy Samba config - which means that the Samba users are mapped to Linux users - although if you use the Samba tools to create your users, then the Linux users should be silently created for you in the background).
I need a hand with it (shame on me)

Regarding file structure and assuming SMB, do you have a planned structure? E.g. are you thinking a single share with different directories (i.e. all users can access the share, but individual folder access is protected with file permissions), or are you thinking separate shares? (E.g. one for each person and only they can access, and another with group access).
Also you explicitly note that you require use of credentials to access the user files, what about the group access? Do you want that to require login too?
Or would they be guest shares (i.e. username 'guest', no password)?
Or do you want all 3 types?

I need 3 types and for be more specific I will details these :

1.- I need a read write permission with password access to one folder just for a person (I.e. user isabel).

2.- I need just a read permission with password access to a group of persons (all the people here)

3.- I need read an write permission to a group of persons using password (i.e. sales)

What about read/write access? Should these users/groups have write access as well, or just read only?

Some people and some group with read only and read and write access. all using password.

And one last question; are you looking for Webmin instructions, or CLI (command line interface - i.e. terminal)? I'm happy to do either, but I personally prefer CLI. IMO it's easier to explain, harder to miss details plus quicker and easier in general (I just have to post commands and you can copy paste them). Having said that, I get that many prefer a UI, so if you'd prefer for Webmin, then that's fine too.
Telling the true, I am interesting on learning both of them

FWIW, either way I'm not a Windows user so I don't recall how to do it OTTOMH and will need to do a bit of reading and probably a little trial and error to refresh my memory before writing something up for you.

I really appreciate the effort.

Really thanks I will be waiting for your response.

Dear Jeremy

Please give me a hand with this:

I have created de folder:

"home/DOC_CUMPLIMIENTO_D"   (owner) fresponsable:ADM_CUMPLIMIENTO    (Mode) 0770

shared as:

Documentacion-LGI   /home/DOC_CUMPLIMIENTO_D      (Security) Read/write to all known users

But user "Fresponsable" can not access the folder as owner to upload files.

Any idea?
