82 The main function of this module is to provide
83 authentification. However the get_template_and_user function has
84 been provided so that a users login information is passed along
85 automatically. This gets loaded into the template.

106 See C<&checkauth> for an explanation of these parameters.

333 Verifies that the user is authorized to run this script. If
334 the user is authorized, a (userid, cookie, session-id, flags)
335 quadruple is returned. If the user is not authorized but does
336 not have the required privilege (see $flagsrequired below), it
337 displays an error page and exits. Otherwise, it displays the
338 login page and exits.
340 Note that C<&checkauth> will return if and only if the user
341 is authorized, so it should be called early on, before any
342 unfinished operations (e.g., if you've opened a file, then
343 C<&checkauth> won't close it for you).
345 C<$query> is the CGI object for the script calling C<&checkauth>.
347 The C<$noauth> argument is optional. If it is set, then no
348 authorization is required for the script.
350 C<&checkauth> fetches user and session information from C<$query> and
351 ensures that the user is authorized to run scripts that require
354 The C<$flagsrequired> argument specifies the required privileges
355 the user must have if the username and password are correct.
356 It should be specified as a reference-to-hash; keys in the hash
357 should be the "flags" for the user, as specified in the Members
358 intranet module. Any key specified must correspond to a "flag"
359 in the userflags table. E.g., { circulate => 1 } would specify
360 that the user must have the "circulate" privilege in order to
361 proceed. To make sure that access control is correct, the
362 C<$flagsrequired> parameter must be specified correctly.
364 The C<$type> argument specifies whether the template should be
365 retrieved from the opac or intranet directory tree. "opac" is
366 assumed if it is not specified; however, if C<$type> is specified,
367 "intranet" is assumed if it is not "opac".
369 If C<$query> does not have a valid session ID associated with it
370 (i.e., the user has not logged in) or if the session has expired,
371 C<&checkauth> presents the user with a login page (from the point of
372 view of the original script, C<&checkauth> does not return). Once the
373 user has authenticated, C<&checkauth> restarts the original script
374 (this time, C<&checkauth> returns).
376 The login page is provided using a HTML::Template, which is set in the
377 systempreferences table or at the top of this file. The variable C<$type>
378 selects which template to use, either the opac or the intranet
379 authentification template.
381 C<&checkauth> returns a user ID, a cookie, and a session ID. The
382 cookie should be sent back to the browser; it verifies that the user
