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.

104 to C<&checkauth> (in this module) to perform authentification.
105 See C<&checkauth> for an explanation of these parameters.
107 The C<template_name> is then used to find the correct template for

110 C<sessionID> is passed to the template. This can be used in templates

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