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