title: setfacl remove group permission
body: <p>I am trying to remove group ACL from a certain folder. It has permissions as below</p>
  
  <pre><code>$ getfacl --all-effective public
  # file: public
  # owner: sse02
  # group: apache
  user::rwx
  group::r-x                      #effective:r-x
  mask::r-x
  other::---
  default:user::rwx
  default:group::r-x              #effective:r-x
  default:group:acct:rwx     #effective:rwx
  default:mask::rwx
  default:other::r-x
  $
  </code></pre>
  
  <p>I wanted to remove the access granted to the group 'acct' with the following command, but it is not simply working</p>
  
  <pre><code>setfacl -x g:acct public
  </code></pre>
  
  <p>What could be going on wrong? Any ideas?</p>
  
  <p>This is a RHEL5 box with ext3 file system.</p>
