  <p>When I try to connect database the below error message is shown.</p>
  
  <p><strong>command</strong>  isql-fb '/var/lib/firebird/2.5/data/employee.fdb' -u firebird -p 'admin'</p>
  
  <p>Statement failed, SQLSTATE = -902
  Your user name and password are not defined. Ask your database administrator to set up a Firebird login.</p>
  
  <p>How can I solve this problem.</p>
