mount -o noperm,unc=\\\\192.168.0.21\\putsharenamehere,username=putusernamehere,password=putpasswordhere -t cifs none /mnt/obb/nas
the mount command has to look like that, in order for it to be seen by apps I had to mount to /mnt/obb/nas (make the nas directory)
that may not be your solution but it should help, I have seen people say they can set up a mounting app to use those parameters.
FYI, if you are going to try the mount out from the command line you need to be in adb shell, not an ssh session.
you can find answers like this in search as well.
dont want to get too off topic but what if you are using NFS. since that doesnt require a username and password what would the command look like?
