Cannot access folder via Samba

ru flag

I set up a Samba server and added a first share to smb.conf:

[Staff]
  path = /media/see-admin/Daten/Staff
  available = yes
  browseable = yes
  guest ok = no
  writeable = no

The server and also the folder show up in Nautilus under "Other locations". When I click on the folder, the following dialogue pops up:

enter image description here

I 'connect as' 'registered user' and type in my user name and password. However, the dialogue briefly disappears and then reappears again. The folder is not being opened. How can I access the folder's contents?

Update

When I change guest ok to yes and click on the folder I receive the error Unable to access location Failed to mount windows share: Permission denied

The log file says:

[2023/04/04 15:37:35.141549,  0] ../../source3/smbd/service.c:168(chdir_current_service)
  chdir_current_service: vfs_ChDir(/media/see-admin/Daten/Staff) failed: Permission denied. Current token: uid=65534, gid=65534, 1 groups: 65534

smb.conf

#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which 
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic 
# errors.

Did you set up a samba password?

Idon't think I did.

At first, may be, to see samba log files. And, then to try (temporarily) to open access for everyone, if your network is surely isolated by router/firewall, by changing "guest ok = yes"

Thank you for your comment. I've updated my question. I hope it helps.

Try following [all the four steps in this tutorial](https://ubuntu.com/tutorials/install-and-configure-samba#1-overview). 1. Overview, 2. Installing Samba, 3. Setting up Samba, 4. Setting up User Accounts and Connecting to Share . It looks like you didn't follow the 4th step.

Still not working. I had performed all steps before except of `sudo ufw allow samba`. I've added the entire `smb.conf` to my question. Maybe it helps.

Accessing `\\server.local/sambashare` via Windows11 returns `The network folder specified is currently mapped sing a different username and password. To connect using a different username and password, first disconnect any existing mappings to this network share.` If I click on the folder in Ubuntu, the user/passwd dialogue opens and nothing happens.

[Staff]
 path = /media/see-admin/Daten/Staff
 available = yes
 browseable = yes
 guest ok = yes
 writeable = no
 
[sambashare]
    comment = Samba on Ubuntu
    path = /home/see-admin/sambashare
    read only = no
    browsable = yes

Your problem on both of these shares is the Linux permissions on the path to the shared folders. THe only user that can access these shares is "see-admin". If you want to force the client user to use the see-admin user name you have to add that user to the samba password database:

sudo smbpasswd -a see-admin

If you want guest user access or any other registered ( meaning a user added to smbpasswd ) you can change your share definition to these:

[Staff]
 path = /media/see-admin/Daten/Staff
 available = yes
 browseable = yes
 guest ok = yes
 writeable = no
 force user = see-admin
 
[sambashare]
    comment = Samba on Ubuntu
    path = /home/see-admin/sambashare
    read only = no
    browsable = yes
    force user = see-admin

Then restart smbd:

sudo service smbd restart

Thank you for your answer! That work from within Ubuntu. First step completed ... now user rights :D

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
