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