Ubuntu automount DFS/SMB share

Install necessary utility:

sudo apt install cifs-utils

Create credentials file called /.smbcredentials for mounting permissions. Use this instead of putting the credentials in the connection string, as later we will be using an automount file and we don't want others to read the credentials:

username=UbuntuMount
password=password
domain=DOMAIN

Restrict the file to root:

sudo chmod 0600 /.smbcredentials

Create the mountpoint --> /mnt/DFSshare

Insert the following string into the file /etc/fstab:

//domain.local/shared /mnt/DFSshare cifs credentials=/.smbcredentials,iocharset=utf8,vers=2.0,gid=1000,uid=1000,file_mode=0777,dir_mode=0777 0 0

Test if the automount works by running this command:

sudo mount -a

If it fails, try manually mounting it in the terminal with this connection string:

sudo mount -t cifs //domain.local/shared /mnt/DFSshare -o credentials=/.smbcredentials

If this works, try rerunning the mount -a command and it should succeed. Reboot and verify it auto mounted
