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