86 The main function of this module is to provide
87 authentification. However the get_template_and_user function has
88 been provided so that a users login information is passed along
89 automatically. This gets loaded into the template.

470 the user is authorized, a (userid, cookie, session-id, flags)
471 quadruple is returned. If the user is not authorized due to
472 insufficent privileges (see $flagsrequired below), it
473 displays an error page and exits. Otherwise, it displays the
474 login page and exits.
476 Note that C<&checkauth> will return if and only if the user
477 is authorized, so it should be called early on, before any
478 unfinished operations (e.g., if you've opened a file, then
479 C<&checkauth> won't close it for you).
481 C<$query> is the CGI object for the script calling C<&checkauth>.
483 The C<$noauth> argument is optional. If it is set, then no
484 authorization is required for the script.
486 C<&checkauth> fetches user and session information from C<$query> and
487 ensures that the user is authorized to run scripts that require
490 The C<$flagsrequired> argument specifies the required privileges
491 the user must have if the username and password are correct.
492 It should be specified as a reference-to-hash; keys in the hash
493 should be the "flags" for the user, as specified in the Members
494 intranet module. Any key specified must correspond to a "flag"
495 in the userflags table. E.g., { circulate => 1 } would specify
496 that the user must have the "circulate" privilege in order to
497 proceed. To make sure that access control is correct, the
498 C<$flagsrequired> parameter must be specified correctly.

501 value of each key in the C<flagsrequired> hash takes on an additional

516 The user must have access to the specific subfunction list, which
517 must correspond to a row in the permissions table.
519 The C<$type> argument specifies whether the template should be
520 retrieved from the opac or intranet directory tree. "opac" is
521 assumed if it is not specified; however, if C<$type> is specified,
522 "intranet" is assumed if it is not "opac".
524 If C<$query> does not have a valid session ID associated with it
525 (i.e., the user has not logged in) or if the session has expired,
526 C<&checkauth> presents the user with a login page (from the point of
527 view of the original script, C<&checkauth> does not return). Once the
528 user has authenticated, C<&checkauth> restarts the original script
529 (this time, C<&checkauth> returns).
531 The login page is provided using a HTML::Template, which is set in the
532 systempreferences table or at the top of this file. The variable C<$type>
533 selects which template to use, either the opac or the intranet
534 authentification template.

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