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