In Thunar, if you type smb://mainpc/maps into the address bar then it 
automounts to /run/user/1000/gvfs/smb-share:server=mainpc,share=maps, 
this is a built in behaviour of the file manager Thunar on Xubuntu 
(assuming your user account id is 1000)

I am primarily testing the share Maps which should be fully read/write
If I attempt to mount myself using mount.cifs  or the automount in 
Thunar (smb://mainpc/maps) the most I can get is read only access.

Most of the time I am mounting shares in fstab and the usual outcome is 
permission denied error 13 and no mount at all (not even read only)

Title:
  Unable to mount network volume on 17.10 Samba server

Status in samba package in Ubuntu:
  Incomplete

Bug description:
  I have a computer with a new 17.10 installation, and I have network
  resources on it that I want to share to other computers on my network,
  using Samba. I set it up the same way with Samba as I did with the old
  16.04 installation, but all the other computers on the network that
  are running Xubuntu can't connect to it like they did before.

  The following are the user experiences of different computers in my
  network connecting to shared SMB resources on other computers:

  16.04 client mount.cifs to 16.04 server: full access
  16.04 client path run/user/1000/gvfs to 16.04 server: full access
  17.10 client mount.cifs to 16.04 server: full access

  16.04 client mount.cifs to 17.10 server: access denied error
  17.10 client mount.cifs to 16.04 server: access denied error
  16.04 client path run/user/1000/gvfs to 17.10 server: read only access
  Windows 10 client explorer map drive to 17.10 server: full access

  the server used to run 16.04 and is now running 17.10. It is the same
  computer and has the same network resources shared on it that it had
  when it was running 16.04.

  The server installation of 17.10 was a clean install but the home
  folder was existing on a different volume and was remounted after the
  install.

  As you can see a Windows 10 computer is the only computer in the
  network that can connect to the Samba share with full access and no
  apparent difference in the user experience.
