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