Problem with Tie::DBI

[John Mulkerin]

I'm trying to use TicketTool with Tie::DBI to hook to a mysql db.  Every
time I get to this part of the code (sub authenticate), I get a "This page
can't be displayed" error screen on my web browser and nothing in my
httpd-error.log or mysql.log.   Can anyone help me?  I've validated I do
have the right table, key etc.  when I go into this part of TicketTool.

Anyone have an idea how I can troubleshoot this further?

 tie my %DB, 'Tie::DBI', {
                db => $self->{TicketDatabase},
                table => $table, key => $userfield,
                user => $dbuser, password => $dbpass,
        } or return ('TT1', "couldn't open databse", '');


Thanks
