title: Cannot connect to my first User in Oracle (SYSTEM)
body: <p><strong>Hello everyone !</strong></p>
  <p>I'm having trouble to connect to my first user (SYSTEM).
  I just did a fresh install on another computer of mine.</p>
  <p>After the install and the password set for the user SYSTEM, I tried the command : <code>SQLPLUS</code></p>
  <p>Then I put the name of my user and the password.</p>
  <p>But everytime I have this error (I'm 100% sure this is the correct password)</p>

  <p>After further research, a lot of people fixed this problem by changing the line :</p>
  <ul>
  <li><code>SQLNET.AUTHENTICATION_SERVICES= (NTS)</code> ; In the sqlnet.ora</li>
  </ul>
  <p>TO</p>
  <ul>
  <li><code>SQLNET.AUTHENTICATION_SERVICES= (NONE)</code></li>
  </ul>
  <p>But of course, by changing this line another error code appear :</p>

  <p>By making this post I hope someone can help me solve this problem for good !
  I don't want to change things on my own. (Things that I don't truly understand and I feel this will break my Oracle even more.</p>
