Using Samba with Active Directory
Samba is a free software suite that provides seamless file and print services for both Windows and Linux systems. By using Samba, you can integrate your Linux server into a Windows Active Directory domain, allowing users to access shared files and printers on the Linux server using their Windows credentials.
To configure Samba with Active Directory, you will need to:
- Install Samba
sudo apt-get install samba
- Create a Samba configuration file
sudo nano /etc/samba/smb.conf
- Configure the Samba configuration file
Add the following lines to the smb.conf
file:
[global]
workgroup = WORKGROUP
security = ads
realm = DOMAIN.LOCAL
ldap server = DC1.DOMAIN.LOCAL
ldap dns = 8.8.8.8
- Create a Samba user account
sudo smbpasswd -a username
- Join the Samba server to the Active Directory domain
sudo net ads join -U username%password
- Restart Samba
sudo service smbd restart
- Test the Active Directory integration
Create a shared directory on the Samba server and try to access it from a Windows client using your Active Directory credentials.
- Troubleshooting
If you encounter any problems, check the Samba log files for errors. The Samba log files are located in the /var/log/samba
directory.

- DNS integration
Samba can be configured to integrate with DNS, allowing users to access shared resources using their fully qualified domain names (FQDNs).
- LDAP integration
Samba can be configured to integrate with LDAP, allowing users to access shared resources using their LDAP credentials.
- NTFS permissions
Samba can be configured to support NTFS permissions, allowing users to set fine-grained permissions on shared resources.
These advanced features can be configured in the smb.conf
file. For more information, refer to the Samba documentation.
Troubleshooting Samba Printer Sharing Issues
If you are experiencing issues with Samba printer sharing on FC24, there are a few things you can check to troubleshoot the problem.
Check the Samba Configuration
First, make sure that Samba is properly configured. You can do this by checking the /etc/samba/smb.conf file. Make sure that the following lines are present and uncommented:
[global]
workgroup = WORKGROUP
server string = Samba Server %v
security = user
map to guest = bad user
dns proxy = no
wins support = yes
wins server = 192.168.1.254
[printers]
comment = All Printers
path = /var/spool/samba
browseable = yes
guest ok = yes
read only = no
create mask = 0700
directory mask = 0700
You may also need to add the following line to the /etc/samba/smb.conf file:
cups options = raw
Check the Firewall
Make sure that the firewall is not blocking Samba traffic. You can do this by checking the firewall configuration. On FC24, you can use the firewall-cmd command to manage the firewall. Make sure that the following ports are open:
firewall-cmd --permanent --add-port=139/tcp
firewall-cmd --permanent --add-port=445/tcp
firewall-cmd --reload
Check the Printer Permissions
Make sure that the printer permissions are set correctly. You can do this by checking the permissions on the /var/spool/samba directory. Make sure that the samba user has read and write permissions.
Check the Printer Driver
Make sure that the printer driver is installed on the client computer. You can do this by checking the printer properties. On Windows, you can open the Control Panel and click on the “Printers” icon. Right-click on the printer and select “Properties.” Click on the “Driver” tab and make sure that the driver is installed.
Check the Printer Connection
Make sure that the printer is connected to the network and that it is powered on.
Restart the Samba Service
If you have made any changes to the Samba configuration, you may need to restart the Samba service. You can do this by running the following command:
systemctl restart smb
Check the Samba Logs
If you are still having problems, you can check the Samba logs for more information. The Samba logs are located in the /var/log/samba directory. You can open the logs with a text editor such as nano or vi.
Additional Troubleshooting Tips
- If you are using a firewall, make sure that it is configured to allow Samba traffic.
- If you are using a router, make sure that it is configured to forward Samba traffic.
- If you are using a VPN, make sure that it is configured to allow Samba traffic.
- If you are using a proxy server, make sure that it is configured to allow Samba traffic.
- If you are using a network switch, make sure that it is configured to allow Samba traffic.

Configuring Samba for File Sharing Between Fedora 24 and iOS Devices
28. Setting Up File Sharing for Specific Samba Users
To fine-tune file sharing permissions for individual Samba users, follow these detailed steps:
Step 1: Create Dedicated Home Directories
Begin by creating a designated home directory for each user who requires access to shared files. Use the command below, replacing “MyUserName” with the actual username:
“`
mkdir /home/MyUserName
“`
Step 2: Assign Ownership and Permissions
Next, assign ownership of the home directory to the corresponding user using the “chown” command:
“`
chown MyUserName /home/MyUserName
“`
Furthermore, grant the user full control over the directory by setting appropriate permissions:
“`
chmod 755 /home/MyUserName
“`
Step 3: Edit the /etc/samba/smb.conf File
Open the Samba configuration file “/etc/samba/smb.conf” using a text editor.
Step 4: Define Share Directory and User Permissions
Within the “[share]” section of the configuration file, add the following entries to define the shared directory and assign permissions for specific users:
“`
[share]
comment = MySharedFiles
path = /home/MyUserName/Shared
valid users = MyUserName
read only = no
“`
In the above snippet, “MySharedFiles” is the share name, “/home/MyUserName/Shared” is the directory path, “MyUserName” specifies the allowed user, and “read only = no” grants read and write access.
Step 5: Save and Restart Samba
Save the updated configuration file and restart the Samba service to apply the changes:
“`
systemctl restart smb
“`
Configuring Samba for File Sharing Between a Linux Server and Cloud Storage Services
Samba is an open-source software suite that allows Linux and Unix systems to share files and printers with Windows and other operating systems. It provides a seamless way to integrate Linux servers into a heterogeneous network environment, enabling users to access and share files across different platforms.
Installing Samba
To install Samba on a Linux server running CentOS 7, execute the following command:
“`
yum install samba samba-common
“`
Configuring Samba
Once Samba is installed, you can configure it by editing the configuration file located at /etc/samba/smb.conf. Open the file with your preferred text editor and make the following changes:
- Set the “workgroup” parameter to match the workgroup of your Windows clients. For example:
- Add a share definition for each directory you want to share. For example, to share the “/home/files” directory with read-write access for all users, add the following:
“`
workgroup = WORKGROUP
“`
“`
[files]
path = /home/files
writable = yes
“`
Starting Samba
After making the necessary changes to the configuration file, start the Samba service with the following command:
“`
systemctl start smb
“`
Testing Samba
To test if Samba is working correctly, try accessing the shared directory from a Windows client. You should be able to browse and access the files in the shared directory.
Additional Samba Configuration Options
Samba offers a wide range of configuration options to customize its behavior. Here are some additional options you may want to consider:
- Security: You can configure Samba to use different security mechanisms, such as user authentication, share-level security, and access control lists (ACLs).
- Performance: Samba can be tuned for optimal performance by adjusting settings such as cache size, connection timeout, and maximum connections.
- Logging: Samba provides a logging facility that can be configured to record various events, such as file access, authentication attempts, and errors.
- Advanced features: Samba supports advanced features such as file locking, directory synchronization, and print sharing.
Parameter | Description |
