I am attempting to use Dancer2::Plugin::Auth::Extensible with Dancer2::Plugin::Auth::Extensible::Provider::LDAP and am running into some problems. For my SSCCE I have created a sample ap according to the directions at https://metacpan.org/pod/Dancer2::Cookbook#Using-DBIx::Class ("dancer2 -a bookstore") and created a restricted route called "restricted". I have entered my LDAP configuration information into the config.yml file, using working data from a successful LDAP search conducted from the command line on the same computer. I attempt to load the restricted route in the browser, I am redirected to a login page, I enter valid credentials and click "Login", and it says "Login failed." Expected behavior is that it display the message "You're logged in!". The code and error messages are below. ("a successful bind must be completed on the connection")

It would seem that something must be different between the LDAP search done from the command line, which is successful, and the LDAP operation (presumably it's a search for the information of the user logging in) that's done by the plugin, which fails. I'm not sure where to start or how to troubleshoot what that difference might be.
