581 The C<$flagsrequired> argument specifies the required privileges
582 the user must have if the username and password are correct.
583 It should be specified as a reference-to-hash; keys in the hash
584 should be the "flags" for the user, as specified in the Members
585 intranet module. Any key specified must correspond to a "flag"
586 in the userflags table. E.g., { circulate => 1 } would specify
587 that the user must have the "circulate" privilege in order to
588 proceed. To make sure that access control is correct, the
589 C<$flagsrequired> parameter must be specified correctly.
591 Koha also has a concept of sub-permissions, also known as
592 granular permissions. This makes the value of each key
593 in the C<flagsrequired> hash take on an additional
598 The user must have access to all subfunctions of the module
599 specified by the hash key.
603 The user must have access to at least one subfunction of the module
604 specified by the hash key.
606 specific permission, e.g., 'export_catalog'
608 The user must have access to the specific subfunction list, which
609 must correspond to a row in the permissions table.
611 The C<$type> argument specifies whether the template should be
612 retrieved from the opac or intranet directory tree. "opac" is
613 assumed if it is not specified; however, if C<$type> is specified,
614 "intranet" is assumed if it is not "opac".
616 If C<$query> does not have a valid session ID associated with it
617 (i.e., the user has not logged in) or if the session has expired,
618 C<&checkauth> presents the user with a login page (from the point of
619 view of the original script, C<&checkauth> does not return). Once the
620 user has authenticated, C<&checkauth> restarts the original script
621 (this time, C<&checkauth> returns).
623 The login page is provided using a HTML::Template, which is set in the
624 systempreferences table or at the top of this file. The variable C<$type>
625 selects which template to use, either the opac or the intranet
626 authentification template.
628 C<&checkauth> returns a user ID, a cookie, and a session ID. The
629 cookie should be sent back to the browser; it verifies that the user
