Bug description

When a file is locked, users are still able to edit it using the desktop client

Steps to reproduce

Scenario:
Two users have access to the same file

• User 1 Locks the file to edit it
• After some seconds the lock is synchronized to user 2
• After that, User2 tries to edit the file and it manages to edit it, even though the file is locked by User1.

Expected behavior

When a user locks a file to edit it, the file should be set as "read-only" for other users.

As far as I remember this was the behaviour some versions ago. I am not sure why this behaviour changed.

@mgallien @allexzander
Do you believe you can bring back the feature which sets the file as read-only when it is locked?

Thank you!
