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