Expected Behavior

When mounting a samba share in ubuntu, using the connect to server option in the nautilus gui, then opening a keepassxc database with keepassxc from that share, it should open and be able to be modified and saved.

Current Behavior

When mounting a samba share, via nautilus, in ubuntu, using the "Connect to server" option in the gui, then using keepassxc to open a database on that server, it opens in read only mode.
There is no warning about locking, or asking if you'd like to open anyway, it just opens, with a yellow bar across the top saying it's open in read only mode.
Modifying other files in this share via other tools works fine (text docs via gedit, renaming things, whatever)

Possible Solution

Mounting thusly works as expected:
mount -t cifs -o username=something,password=something //1.2.3.4/foo /mnt

Steps to Reproduce (for bugs)

1.Mount a samba share with nautilus connect to server option
2.open a keepassxc file in the share
3.
4.

Context

I want to have a keepassxc db on a shared location in my network, and access it from a few different computers.
