478 Verifies that the user is authorized to run this script. If
479 the user is authorized, a (userid, cookie, session-id, flags)
480 quadruple is returned. If the user is not authorized but does
481 not have the required privilege (see $flagsrequired below), it
482 displays an error page and exits. Otherwise, it displays the
483 login page and exits.
485 Note that C<&checkauth> will return if and only if the user
486 is authorized, so it should be called early on, before any
487 unfinished operations (e.g., if you've opened a file, then
488 C<&checkauth> won't close it for you).
490 C<$query> is the CGI object for the script calling C<&checkauth>.
492 The C<$noauth> argument is optional. If it is set, then no
493 authorization is required for the script.
495 C<&checkauth> fetches user and session information from C<$query> and
496 ensures that the user is authorized to run scripts that require
499 The C<$flagsrequired> argument specifies the required privileges
500 the user must have if the username and password are correct.
501 It should be specified as a reference-to-hash; keys in the hash
502 should be the "flags" for the user, as specified in the Members
503 intranet module. Any key specified must correspond to a "flag"
504 in the userflags table. E.g., { circulate => 1 } would specify
505 that the user must have the "circulate" privilege in order to
506 proceed. To make sure that access control is correct, the
507 C<$flagsrequired> parameter must be specified correctly.
509 Koha also has a concept of sub-permissions, also known as
510 granular permissions. This makes the value of each key
511 in the C<flagsrequired> hash take on an additional
516 The user must have access to all subfunctions of the module
517 specified by the hash key.
521 The user must have access to at least one subfunction of the module
522 specified by the hash key.
524 specific permission, e.g., 'export_catalog'
526 The user must have access to the specific subfunction list, which
527 must correspond to a row in the permissions table.
529 The C<$type> argument specifies whether the template should be
530 retrieved from the opac or intranet directory tree. "opac" is
531 assumed if it is not specified; however, if C<$type> is specified,
532 "intranet" is assumed if it is not "opac".
534 If C<$query> does not have a valid session ID associated with it
535 (i.e., the user has not logged in) or if the session has expired,
536 C<&checkauth> presents the user with a login page (from the point of
537 view of the original script, C<&checkauth> does not return). Once the
538 user has authenticated, C<&checkauth> restarts the original script
539 (this time, C<&checkauth> returns).
541 The login page is provided using a HTML::Template, which is set in the
542 systempreferences table or at the top of this file. The variable C<$type>
543 selects which template to use, either the opac or the intranet
544 authentification template.
546 C<&checkauth> returns a user ID, a cookie, and a session ID. The
547 cookie should be sent back to the browser; it verifies that the user
556 # If Version syspref is unavailable, it means Koha is beeing installed,
