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.

103 This call passes the C<query>, C<flagsrequired> and C<authnotrequired>
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
108 the page. The authenticated users details are loaded onto the

110 C<sessionID> is passed to the template. This can be used in templates
111 if cookies are disabled. It needs to be put as and input to every

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