How do I use a credential file for CIFS in /etc/fstab?
I’m having a problem with fstab on Server 18.04. I’m trying to mount a number of Windows Server network shares. If I put the username and password into each line of fstab and do sudo mount -a, it works fine. However, when I try to use a “credentials” file, it all goes pear-shaped.
So this:
//server/share /mount/point cifs ro,auto,user=user,password=password 0 0
…works fine.
However, if I try this:
//server/share /mount/point cifs ro,auto,credentials=/etc/.smbcredentials 0 0
…with .smbcredentials containing the following:
user=username
password=password
domain=domain
…this does not work. sudo mount -a -v outputs the following:
/ : ignored
/boot/efi : already mounted
none : ignored
domain=mydomain
,prefixpath=Projects/XYZ,pass=********.168.1.10,unc=servershare,user=username
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
168.1.10 is the partial IP address of the server on which the shares that I want to mount are located. It appears that the password is being concatenated onto the IP of the server.
So, what am I doing wrong? Any help would be much appreciated.

Hi welcome to Ask Ubuntu! The credentials file is supposed to useusername=usernamerather thanuser=..though I can't see how that would cause this problem. Was that just a typo in the post?

Hi, I've seen examples that use either user or username. I'm not sure if you can use either or only one or the other. Paul

Yeah, I've just tried it on a 14.04 server and you're correct. Either of them work. I'm afraid I don't have anything else to offer, hopefully someone more knowledgeable will be along to help.

Does your credentials file have the correct (Unix-style) line terminations? or does it use Windows style CRLF?

My working credentials file is located in my ~ folder and looks like this
username=[username]
password=[password]
Its permissions are -rw------- and it is owned by my user.
The corresponding fstab line is
//[URL]/[sharename] /media/[mountpoint] cifs vers=3.0,credentials=/home/[username]/.sharelogin,iocharset=utf8,file_mode=0777,dir_mode=0777,uid=[username],gid=[username],nofail 0 0
I don't use "domain" but that doesn't mean that you don't need it.
