! This directive allows you to specify a custom SQL-query that
! mod_authn_dbi will use when authenticating users. It is quite flexible
! and can be used to shoot a lot of problems (including your
! foot). Changing its value may also change the behaviour of
! <code>AuthnDbiUsernameField</code>, <code>AuthnDbiPasswordField</code>,
! <code>AuthnDbiIsActiveField</code>, <code>AuthnDbiTable</code> from
! what is documented in here.
! </p>
! <p>
! For <em>each request</em> that is received (not just at configuration
! time), mod_authn_dbi will go through the following steps:
! <ol>
! <li><b>Replace variables in the query string by their corresponding
! values</b><br />
! The query string may contain any number of placeholders for variables
! of the format &{<var>variablename</var>}. For each request, this
! placeholder is replaced by the current value. The Variables supported
! variables come from the configuration of mod_authn_dbi or attributes
! of the current request. See below for a list of supported variables
! and their meaning.
! </li>
! <li><b>Execute the query in the database that was configured</b>
!
! </li>
! <li><b>Select from the result the field with the name configured by
! <code>PasswordField</code> (or its default).</b>
! </li>
! <li><b>Interpret the value according to <code>AuthnDbiPasswordFormat</code> and use it for
! authenticating the request.</b>
