87 The main function of this module is to provide
88 authentification. However the get_template_and_user function has
89 been provided so that a users login information is passed along
90 automatically. This gets loaded into the template.

115 if cookies are disabled. It needs to be put as and input to every

480 C<&checkauth> won't close it for you).
482 C<$query> is the CGI object for the script calling C<&checkauth>.
484 The C<$noauth> argument is optional. If it is set, then no
485 authorization is required for the script.
487 C<&checkauth> fetches user and session information from C<$query> and
488 ensures that the user is authorized to run scripts that require
491 The C<$flagsrequired> argument specifies the required privileges
492 the user must have if the username and password are correct.
493 It should be specified as a reference-to-hash; keys in the hash
494 should be the "flags" for the user, as specified in the Members
495 intranet module. Any key specified must correspond to a "flag"
496 in the userflags table. E.g., { circulate => 1 } would specify
497 that the user must have the "circulate" privilege in order to
498 proceed. To make sure that access control is correct, the
499 C<$flagsrequired> parameter must be specified correctly.
501 Koha also has a concept of sub-permissions, also known as
502 granular permissions. This makes the value of each key
503 in the C<flagsrequired> hash take on an additional
508 The user must have access to all subfunctions of the module
509 specified by the hash key.
513 The user must have access to at least one subfunction of the module
514 specified by the hash key.
516 specific permission, e.g., 'export_catalog'
518 The user must have access to the specific subfunction list, which
519 must correspond to a row in the permissions table.
521 The C<$type> argument specifies whether the template should be
522 retrieved from the opac or intranet directory tree. "opac" is
523 assumed if it is not specified; however, if C<$type> is specified,
524 "intranet" is assumed if it is not "opac".
526 If C<$query> does not have a valid session ID associated with it
527 (i.e., the user has not logged in) or if the session has expired,
528 C<&checkauth> presents the user with a login page (from the point of
529 view of the original script, C<&checkauth> does not return). Once the
530 user has authenticated, C<&checkauth> restarts the original script
531 (this time, C<&checkauth> returns).
533 The login page is provided using a HTML::Template, which is set in the
534 systempreferences table or at the top of this file. The variable C<$type>
535 selects which template to use, either the opac or the intranet
536 authentification template.
538 C<&checkauth> returns a user ID, a cookie, and a session ID. The
539 cookie should be sent back to the browser; it verifies that the user
