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