2. Create a text file in /root with your file server credentials:
sudo vim /root/.windowsShare
3. Add the following contents:
username=myuser password=secretpassword
4. Create a mount point for your share:
sudo mkdir /mnt/my_share
5. Open /etc/fstab with your favorite text editor, e.g. vim:
sudo vim /etc/fstab
6. Add the following line at the end of the file:
//server.domain.com/share_name /mnt/my_share cifs defaults,_netdev,uid=my_unix_user,credentials=/root/.windowsShare 0 0
7. Mount the share to your system (or reboot):
