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