Hi,
I have a strange problem. When I run this in the debugger, I see a successful su to the passed user. But when I run this without the debugger, I get the message "Authentication Failed".

I used Net::SSH::Expect for the $ssh.

This is my code to connect and do a su user. 

sub su_login {

     my ($self, $user, $pass) = @_;

     my $ssh = $self->ssh();
     my $log = $self->log();
     my $cmd = '';
     if($user eq 'root') {
         $cmd = 'su -';
     } else {
         $cmd = "su $user";
     }
     $ssh->send($cmd);
     $ssh->waitfor('Password:\s*\z', 3) or return (undef, "Cannot su a
+s $user");
     $ssh->send($pass);
     my $output = $ssh->exec('whoami');
     $log->message($output);
     if ($output =~ /sorry|failure/i )  { 
         $log->error("Cannot su as $user");
         return (undef, "Failed to login as $user");
     } else {
         $log->message("Successfully logged in as $user");
     }
     return ($ssh, "su $user successful");
 }
