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