467 Verifies that the user is authorized to run this script. If
468 the user is authorized, a (userid, cookie, session-id, flags)
469 quadruple is returned. If the user is not authorized but does
470 not have the required privilege (see $flagsrequired below), it
471 displays an error page and exits. Otherwise, it displays the
472 login page and exits.
474 Note that C<&checkauth> will return if and only if the user
475 is authorized, so it should be called early on, before any
476 unfinished operations (e.g., if you've opened a file, then
477 C<&checkauth> won't close it for you).
479 C<$query> is the CGI object for the script calling C<&checkauth>.
481 The C<$noauth> argument is optional. If it is set, then no
482 authorization is required for the script.
484 C<&checkauth> fetches user and session information from C<$query> and
485 ensures that the user is authorized to run scripts that require
488 The C<$flagsrequired> argument specifies the required privileges
489 the user must have if the username and password are correct.
490 It should be specified as a reference-to-hash; keys in the hash
491 should be the "flags" for the user, as specified in the Members
492 intranet module. Any key specified must correspond to a "flag"
493 in the userflags table. E.g., { circulate => 1 } would specify
494 that the user must have the "circulate" privilege in order to
495 proceed. To make sure that access control is correct, the
496 C<$flagsrequired> parameter must be specified correctly.
498 Koha also has a concept of sub-permissions, also known as
499 granular permissions. This makes the value of each key
500 in the C<flagsrequired> hash take on an additional
505 The user must have access to all subfunctions of the module
506 specified by the hash key.
510 The user must have access to at least one subfunction of the module
511 specified by the hash key.
513 specific permission, e.g., 'export_catalog'
515 The user must have access to the specific subfunction list, which
516 must correspond to a row in the permissions table.
518 The C<$type> argument specifies whether the template should be
519 retrieved from the opac or intranet directory tree. "opac" is
520 assumed if it is not specified; however, if C<$type> is specified,
521 "intranet" is assumed if it is not "opac".
523 If C<$query> does not have a valid session ID associated with it
524 (i.e., the user has not logged in) or if the session has expired,
525 C<&checkauth> presents the user with a login page (from the point of
526 view of the original script, C<&checkauth> does not return). Once the
527 user has authenticated, C<&checkauth> restarts the original script
528 (this time, C<&checkauth> returns).
530 The login page is provided using a HTML::Template, which is set in the
531 systempreferences table or at the top of this file. The variable C<$type>
532 selects which template to use, either the opac or the intranet
533 authentification template.
535 C<&checkauth> returns a user ID, a cookie, and a session ID. The
536 cookie should be sent back to the browser; it verifies that the user
