title: at command throws 'cannot set egid: Operation not permitted error'
body: <p>I'm trying to execute a command using the following command:</p>
  
  <pre><code>/usr/local/bin/php xxx.php | at now + 10 minutes
  </code></pre>
  
  <p>However, terminal throws this error:</p>
  
  <pre><code>cannot set egid: Operation not permitted error
  </code></pre>
  
  <p>I tried adding the user to /etc/at.allow but that doesn't help. I also removed /etc/at.deny, but that also didn't help. Any ideas what is up? How can I give permission to the user to utilize the at command?</p>
