84 authentification. However the get_template_and_user function has
85 been provided so that a users login information is passed along

334 Verifies that the user is authorized to run this script. If
335 the user is authorized, a (userid, cookie, session-id, flags)
336 quadruple is returned. If the user is not authorized but does
337 not have the required privilege (see $flagsrequired below), it
338 displays an error page and exits. Otherwise, it displays the
339 login page and exits.
341 Note that C<&checkauth> will return if and only if the user
342 is authorized, so it should be called early on, before any
343 unfinished operations (e.g., if you've opened a file, then
344 C<&checkauth> won't close it for you).
346 C<$query> is the CGI object for the script calling C<&checkauth>.
348 The C<$noauth> argument is optional. If it is set, then no
349 authorization is required for the script.
351 C<&checkauth> fetches user and session information from C<$query> and
352 ensures that the user is authorized to run scripts that require
355 The C<$flagsrequired> argument specifies the required privileges
356 the user must have if the username and password are correct.
357 It should be specified as a reference-to-hash; keys in the hash
358 should be the "flags" for the user, as specified in the Members
359 intranet module. Any key specified must correspond to a "flag"
360 in the userflags table. E.g., { circulate => 1 } would specify
361 that the user must have the "circulate" privilege in order to
362 proceed. To make sure that access control is correct, the
363 C<$flagsrequired> parameter must be specified correctly.
365 If the GranularPermissions system preference is ON, the
366 value of each key in the C<flagsrequired> hash takes on an additional

377 specified by the hash key.
379 =item specific permission, e.g., 'export_catalog'
381 The user must have access to the specific subfunction list, which
382 must correspond to a row in the permissions table.
384 The C<$type> argument specifies whether the template should be
385 retrieved from the opac or intranet directory tree. "opac" is
386 assumed if it is not specified; however, if C<$type> is specified,
387 "intranet" is assumed if it is not "opac".
389 If C<$query> does not have a valid session ID associated with it
390 (i.e., the user has not logged in) or if the session has expired,
391 C<&checkauth> presents the user with a login page (from the point of
392 view of the original script, C<&checkauth> does not return). Once the
393 user has authenticated, C<&checkauth> restarts the original script
394 (this time, C<&checkauth> returns).
396 The login page is provided using a HTML::Template, which is set in the
397 systempreferences table or at the top of this file. The variable C<$type>
398 selects which template to use, either the opac or the intranet
399 authentification template.

402 cookie should be sent back to the browser; it verifies that the user
