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

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