by adding unneeded complexity you've lost what is happening

why you wrote this way: 

my ($dfHost, $dfPort, $dfUser,$dfPassword) 
    = map {$fRight->Entry(    -textvariable=>$_ )->pack(-side=>'top',-
+pady=>3)}
        qw/\$user \$password/;

you assign 2-element list to 4 variables, so last two are undefined.

But more to the point, if you'll write 

$fRight->Entry(    -textvariable=>\$user )->pack(-side=>'top',-pady=>3
+);
$fRight->Entry(    -textvariable=>\$password )->pack(-side=>'top',-pad
+y=>3);

your code works as expected.
I can not explain it, but I know it
:)

(addition) qw/\$user .../ does not do what you want
