title: how to lock files and make it read-only in svn
body: <p>I am using VisualSVN Server to store my files in a repository. Then I check them out using TortoiseSVN client. I want to make sure that when one client has locked and started working on a file, the other clients should not be able to make changes to the same file as well. When they check out the repository they should see the file as "read-only". </p>
  
  <p>In order to do this I went to the config file of the TortoiseSVN and added the property <code>"*.* = svn:needs-lock=true"</code> and I also uncommented the line <code>enable-auto-props = yes</code>, both in the server and the client side to be sure. But still after making the lock, the other clients are able to modify the file, though they cannot commit it, since the lock is already made.</p>
  
  <p>Can anyone please take a look at this and tell me what I am doing wrong?</p>
