Hi ,

The passwd and usernm should be different from 'spice' and 'sugar' respectively for the error to show ( the both the usernm and passwd should change together from their values then only it shall error) in accordance to the post

     if (($usernm ne 'sugar') || ($passwd ne 'spice')){

         print " the error of authorization       \n";
         #.......

     }

this shall be like the usernm should be sugar and the passwd should be spice, if either one changes the error is shown
