604 ($userid, $cookie, $sessionID) = &checkauth($query, $noauth, $flagsrequired, $type);
606 Verifies that the user is authorized to run this script. If
607 the user is authorized, a (userid, cookie, session-id, flags)
608 quadruple is returned. If the user is not authorized but does
609 not have the required privilege (see $flagsrequired below), it
610 displays an error page and exits. Otherwise, it displays the
611 login page and exits.
613 Note that C<&checkauth> will return if and only if the user
614 is authorized, so it should be called early on, before any
615 unfinished operations (e.g., if you've opened a file, then
616 C<&checkauth> won't close it for you).
618 C<$query> is the CGI object for the script calling C<&checkauth>.
620 The C<$noauth> argument is optional. If it is set, then no
621 authorization is required for the script.
623 C<&checkauth> fetches user and session information from C<$query> and
624 ensures that the user is authorized to run scripts that require
627 The C<$flagsrequired> argument specifies the required privileges
628 the user must have if the username and password are correct.
629 It should be specified as a reference-to-hash; keys in the hash
630 should be the "flags" for the user, as specified in the Members
631 intranet module. Any key specified must correspond to a "flag"
632 in the userflags table. E.g., { circulate => 1 } would specify
633 that the user must have the "circulate" privilege in order to
634 proceed. To make sure that access control is correct, the
635 C<$flagsrequired> parameter must be specified correctly.
637 Koha also has a concept of sub-permissions, also known as
638 granular permissions. This makes the value of each key
639 in the C<flagsrequired> hash take on an additional
644 The user must have access to all subfunctions of the module
645 specified by the hash key.
649 The user must have access to at least one subfunction of the module
650 specified by the hash key.
652 specific permission, e.g., 'export_catalog'
654 The user must have access to the specific subfunction list, which
655 must correspond to a row in the permissions table.
657 The C<$type> argument specifies whether the template should be
658 retrieved from the opac or intranet directory tree. "opac" is
659 assumed if it is not specified; however, if C<$type> is specified,
660 "intranet" is assumed if it is not "opac".
662 If C<$query> does not have a valid session ID associated with it
663 (i.e., the user has not logged in) or if the session has expired,
664 C<&checkauth> presents the user with a login page (from the point of
665 view of the original script, C<&checkauth> does not return). Once the
666 user has authenticated, C<&checkauth> restarts the original script
667 (this time, C<&checkauth> returns).
669 The login page is provided using a HTML::Template, which is set in the
670 systempreferences table or at the top of this file. The variable C<$type>
671 selects which template to use, either the opac or the intranet
672 authentification template.
674 C<&checkauth> returns a user ID, a cookie, and a session ID. The
675 cookie should be sent back to the browser; it verifies that the user
