C4::Auth - Authenticates Koha users
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use CGI;
|
|
use C4::Auth;
|
|
|
|
my $query = new CGI;
|
|
|
|
my ($template, $borrowernumber, $cookie)
|
|
= get_template_and_user(
|
|
{
|
|
template_name => "opac-main.tmpl",
|
|
query => $query,
|
|
type => "opac",
|
|
authnotrequired => 1,
|
|
flagsrequired => {borrow => 1},
|
|
}
|
|
);
|
|
|
|
print $query->header(
|
|
-type => 'utf-8',
|
|
-cookie => $cookie
|
|
), $template->output;
|
|
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The main function of this module is to provide
|
|
authentification. However the get_template_and_user function has
|
|
been provided so that a users login information is passed along
|
|
automatically. This gets loaded into the template.
|
|
|
|

=item get_template_and_user
|
|
|
|
my ($template, $borrowernumber, $cookie)
|
|
= get_template_and_user(
|
|
{
|
|
template_name => "opac-main.tmpl",
|
|
query => $query,
|
|
type => "opac",
|
|
authnotrequired => 1,
|
|
flagsrequired => {borrow => 1},
|
|
}
|
|
);
|
|
|
|
This call passes the C<query>, C<flagsrequired> and C<authnotrequired>
|
|
to C<&checkauth> (in this module) to perform authentification.
|
|
See C<&checkauth> for an explanation of these parameters.
|
|
|
|
The C<template_name> is then used to find the correct template for
|
|
the page. The authenticated users details are loaded onto the
|
|
template in the HTML::Template LOOP variable C<USER_INFO>. Also the
|
|
C<sessionID> is passed to the template. This can be used in templates
|
|
if cookies are disabled. It needs to be put as and input to every
|
|
authenticated page.
|
|
|
|
More information on the C<gettemplate> sub can be found in the
|
|
Output.pm module.

|
|
|
|
Verifies that the user is authorized to run this script. If
|
|
the user is authorized, a (userid, cookie, session-id, flags)
|
|
quadruple is returned. If the user is not authorized but does
|
|
not have the required privilege (see $flagsrequired below), it
|
|
displays an error page and exits. Otherwise, it displays the
|
|
login page and exits.
|
|
|
|
Note that C<&checkauth> will return if and only if the user
|
|
is authorized, so it should be called early on, before any
|
|
unfinished operations (e.g., if you've opened a file, then
|
|
C<&checkauth> won't close it for you).
|
|
|
|
C<$query> is the CGI object for the script calling C<&checkauth>.
|
|
|
|
The C<$noauth> argument is optional. If it is set, then no
|
|
authorization is required for the script.
|
|
|
|
C<&checkauth> fetches user and session information from C<$query> and
|
|
ensures that the user is authorized to run scripts that require
|
|
authorization.
|
|
|
|
The C<$flagsrequired> argument specifies the required privileges
|
|
the user must have if the username and password are correct.
|
|
It should be specified as a reference-to-hash; keys in the hash
|
|
should be the "flags" for the user, as specified in the Members
|
|
intranet module. Any key specified must correspond to a "flag"
|
|
in the userflags table. E.g., { circulate => 1 } would specify
|
|
that the user must have the "circulate" privilege in order to
|
|
proceed. To make sure that access control is correct, the
|
|
C<$flagsrequired> parameter must be specified correctly.
|
|
|
|
The C<$type> argument specifies whether the template should be
|
|
retrieved from the opac or intranet directory tree. "opac" is
|
|
assumed if it is not specified; however, if C<$type> is specified,
|
|
"intranet" is assumed if it is not "opac".
|
|
|
|
If C<$query> does not have a valid session ID associated with it
|
|
(i.e., the user has not logged in) or if the session has expired,
|
|
C<&checkauth> presents the user with a login page (from the point of
|
|
view of the original script, C<&checkauth> does not return). Once the
|
|
user has authenticated, C<&checkauth> restarts the original script
|
|
(this time, C<&checkauth> returns).
|
|
|
|
The login page is provided using a HTML::Template, which is set in the
|
|
systempreferences table or at the top of this file. The variable C<$type>
|
|
selects which template to use, either the opac or the intranet
|
|
authentification template.
|
|
|
|
C<&checkauth> returns a user ID, a cookie, and a session ID. The
|
|
cookie should be sent back to the browser; it verifies that the user
|
|
has authenticated.
