title: moodle authenticate the user by username and password - web service
body: <p>I was looking for a way to authenticate a user on my site against moodle web service.</p>
  
  <p>It seems that there is no web service that recives username and password and returns the user data.</p>
  
  <p>Is it possible to overcome this ? i need to authenticate a user on my wp site against the moodle system</p>
  
  <p>Thanks</p>
