I have been struggling with this for a couple days, I could get to samba shares on an ubuntu 16.04 desktop system with my lubuntu 18.04 new installation using smb4k, but not in fstab. I used some of the parameters listed by 'mount' after mounting a share using smb4k. What I found was the
credentials=/etc/samba/auth.myserver.me did not work like it did with ubuntu 16.04. The following syntax would allow a mount:
//192.168.10.66/servershare /mnt/localdir cifs rw,vers=1.0,sec=ntlmssp,username=USER,password=PASSWORD,domain=YOURDOMAIN,uid=LOCALUSER,gid=LOCALUSER,posixpaths,mapposix,acl 0 0
What I do not know is which of the above options are required. Use your own values for USER, PASSWORD, and YOURDOMAIN.
Whenever I used the
credentials=/etc/samba/auth.myserver.me, I would always get a 'Permission denied' message. Apparently ubuntu 18.04 is not properly accessing the credentials file listed in
fstab or the syntax has changed.
You may have to experiment with the uid and gid. I normally only login as a particular user, which I am calling LOCALUSER, the default group for that login would also be LOCALUSER.
