Non-Root Users Can't See My Samba Share: Troubleshooting the vfs.provider.smbj/access-denied Issue

Welcome to the Linux community! I'm excited to share my first post with you all, and I hope to get some valuable insights from your experiences. I'm currently setting up a Samba share on my Ubuntu Desktop 24.04LTS machine, but I'm facing an issue where non-root users can't see the share. The error message I'm getting is vfs.provider.smbj/access-denied. In this article, we'll explore the possible causes and solutions to this problem.

Understanding Samba and Permissions

Before we dive into the troubleshooting process, let's quickly review the basics of Samba and permissions. Samba is a free and open-source implementation of the SMB/CIFS protocol, which allows Linux systems to share files and printers with Windows and other Samba clients. When it comes to permissions, Samba uses a combination of Linux file system permissions and Samba-specific permissions to control access to shared resources.

Samba Configuration

To troubleshoot the vfs.provider.smbj/access-denied issue, we need to take a closer look at the Samba configuration. By default, Samba uses the smb.conf file to store its configuration settings. This file is usually located in the /etc/samba/ directory.

Step 1: Verify Samba Configuration

Let's start by verifying the Samba configuration. Open the smb.conf file in a text editor and look for the following settings:

browseable = yes: This setting controls whether the share is visible to clients.
valid users = %S: This setting specifies the users who are allowed to access the share.
force user = nobody: This setting forces all connections to use the nobody user.

If you're using a different Samba configuration file, make sure to adjust the file path accordingly.

Step 2: Check Linux File System Permissions

Next, let's check the Linux file system permissions for the shared directory. Use the ls command to verify the ownership and permissions of the directory:

ls -ld /path/to/shared/directory

Make sure that the directory is owned by the nobody user and has the correct permissions:

chown nobody:nogroup /path/to/shared/directory
chmod 755 /path/to/shared/directory

Step 3: Verify Samba User Accounts

Now, let's verify that the Samba user accounts are correctly configured. Use the smbpasswd command to list the Samba user accounts:

smbpasswd -L

Make sure that the Samba user accounts are correctly mapped to the Linux user accounts:

smbpasswd -a username

Step 4: Restart Samba Services

Finally, let's restart the Samba services to apply the changes:

sudo service samba restart

Troubleshooting the vfs.provider.smbj/access-denied Issue

If you've followed the steps above and still encounter the vfs.provider.smbj/access-denied issue, here are some additional troubleshooting steps to try:

Check the Samba log files: Use the smbclient command to connect to the share and check the Samba log files for any error messages.
Verify the Samba version: Make sure that you're running the latest version of Samba.
Check the Linux kernel version: Make sure that you're running a compatible Linux kernel version.

In this article, we've explored the possible causes and solutions to the vfs.provider.smbj/access-denied issue on Ubuntu Desktop 24.04LTS. By following the troubleshooting steps outlined above, you should be able to resolve the issue and allow non-root users to access the Samba share. If you're still experiencing issues, feel free to share more details about your setup, and I'll do my best to help you troubleshoot the problem.
