657 authorization is required for the script.
659 C<&checkauth> fetches user and session information from C<$query> and
660 ensures that the user is authorized to run scripts that require
663 The C<$flagsrequired> argument specifies the required privileges
664 the user must have if the username and password are correct.
665 It should be specified as a reference-to-hash; keys in the hash
666 should be the "flags" for the user, as specified in the Members
667 intranet module. Any key specified must correspond to a "flag"
668 in the userflags table. E.g., { circulate => 1 } would specify
669 that the user must have the "circulate" privilege in order to
670 proceed. To make sure that access control is correct, the
671 C<$flagsrequired> parameter must be specified correctly.
673 Koha also has a concept of sub-permissions, also known as
674 granular permissions. This makes the value of each key
675 in the C<flagsrequired> hash take on an additional
680 The user must have access to all subfunctions of the module
681 specified by the hash key.
685 The user must have access to at least one subfunction of the module
686 specified by the hash key.
688 specific permission, e.g., 'export_catalog'
690 The user must have access to the specific subfunction list, which
691 must correspond to a row in the permissions table.
693 The C<$type> argument specifies whether the template should be
694 retrieved from the opac or intranet directory tree. "opac" is
695 assumed if it is not specified; however, if C<$type> is specified,
696 "intranet" is assumed if it is not "opac".
698 If C<$query> does not have a valid session ID associated with it
699 (i.e., the user has not logged in) or if the session has expired,
700 C<&checkauth> presents the user with a login page (from the point of
701 view of the original script, C<&checkauth> does not return). Once the
702 user has authenticated, C<&checkauth> restarts the original script
703 (this time, C<&checkauth> returns).
705 The login page is provided using a HTML::Template, which is set in the
706 systempreferences table or at the top of this file. The variable C<$type>
707 selects which template to use, either the opac or the intranet
708 authentification template.
710 C<&checkauth> returns a user ID, a cookie, and a session ID. The
711 cookie should be sent back to the browser; it verifies that the user
