title: How to define login and password in Firebird based application?
body: <p>I know, this is not a strictly programming error, because I did not wrote this program, but I have a Streamsoft Pro installed on one PC and when I copied all program data to second machine I got error:</p>
  
  <pre><code>Unsuccessful execution caused by a system error that precludes successful execution of subsequent statements.
  unsupported on-disk structure for file c:\STREAM soft\STREAM soft SQL\Baza\SYSTEMST.FB; found 11.2, support 11.1
  </code></pre>
  
  <p>Found <a href="https://stackoverflow.com/questions/43643098/why-do-i-get-an-unsupported-on-disk-structure-error-in-flamerobin">here</a> tat it is Firebird version related error so I updated it to 2.5.8 and now I get other error:</p>
  
  <pre><code>DMSystem.SystemDatabase:
  Unsuccessful execution caused by a system error that precludes successful execution of subsequent statements.
  Your username and password are not defined. Ask your database administrator to set up a Firebird login.
  </code></pre>
  
  <p>And my question is:
  How to set up those?</p>
