title: Oracle Forms App cannot connect to DB (Oracle 10g)
body: <p>I have a legacy application created in Oracle Forms. </p>
  
  <p>It's a 10g Oracle database, and Forms 6i. Database works OK, I've set up TNS names correctly, tnsping works, I can connect using sqlplus and sql developer.</p>
  
  <p>I think that Forms is also OK, since it gives me a form where the user should input credentials.</p>
  
  <p>The problem is Forms users can't connect. That very first form that is being called has line:</p>
  
  <pre><code>LOGON('user','pass@TNS', false);
  </code></pre>
  
  <p>this line gives me form_failure, but I don't know what is the problem. Credentials are definitely correct.</p>
  
  <p>If I try like this:</p>
  
  <pre><code>LOGON('user','pass@TNS', true);
  </code></pre>
  
  <p>then forms gives me an additional generic dialog to login if the former was unsuccessful. That won't let me in also (I've tried a lot of user/pass combos).</p>
  
  <p>I also did some debugging (as much as I know in forms developer) but without success.</p>
  
  <p>I would appreciate very much any help or something that could point me in right direction.</p>
