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