Turn on Apache::DBI debugging. From the docs: 
    To enable debugging the variable $Apache::AuthDBI::DEBUG
       must be set. This can either be done in startup.pl or in
       the user script. Setting the variable to 1, just reports
       about a new connect. Setting the variable to 2 enables
       full debug output.
