title: File access permission denied even after setting ACL in linux
body: <p>I've set ACL for an svn folder as follows</p>
  
  <pre><code># file: www
  # owner: aks
  # group: users
  user::rwx
  group::rwx    
  group:users:rwx
  mask::r-x
  other::r-x
  default:user::rwx
  default:group::rwx
  default:other::r-x
  </code></pre>
  
  <p>but despite this, when another user does an svn up, he gets</p>
  
  <pre><code>svn: Can't open file 'www/.svn/lock': Permission denied
  </code></pre>
  
  <p>What am i missing</p>
