You can accomplish this using version 0.15 of Catalyst::Model::LDAP.

The basic structure goes something like this:

1. In MyApp::Model::LDAP, override ACCEPT_CONTEXT to store the
   username and password from the request.

2. In MyApp::LDAP::Connection, override bind to use the username and
   password from step 1.

If your LDAP server expects just a simple DN and password pair, you
might not even need MyApp::LDAP::Connection.  For example:

package MyApp::Model::LDAP;

use Class::C3;

sub ACCEPT_CONTEXT {
    my $self = shift;
    my $c = $_[0];

    $self{dn} = $c->req->param('username');
    $self{password} = $c->req->param('password');

    $self->next::method(@_);
}
