title: Freeradius users operators
body: <p>I faced with one issue, which I can't understand in Freeradius <strong>users</strong> file.
  My goal is just authenticate external user "shad" with password "test".
  I added line in /etc/raddb/users the following line:
  <strong><em>shad    Cleartext-Password == "test"</em></strong>
  Result was Reject. If I change <strong>"=="</strong> operator to <strong>":="</strong> Authentication is successful.
  So my question is the following:
  Why I can't use <strong>"=="</strong> operator while FreeRadius documentation tells:
  <em>"Attribute == Value
  As a check item, it matches if the named attribute is present in the request, AND has the given value."</em></p>
  
  <p>And one more question.
  In some resourses I faced with such lines:
  <strong><em>shad  Auth-Type := Local, User-Password == "test"</em></strong>
  I tried and it doesn't work. Responce is Reject with log:
  [pap] WARNING! No "known good" password found for the user.  Authentication may fail because of this.</p>
