Jonathan Druart 2b90ea2cb0 Bug 17829: Move GetMember to Koha::Patron 
GetMember returned a patron given a borrowernumber, cardnumber or
userid.
All of these 3 attributes are defined as a unique key at the DB level
and so we can use Koha::Patrons->find to replace this subroutine.
Additionaly GetMember set category_type and description.

=head1 NAME
C4::Auth - Authenticates Koha users
=head1 SYNOPSIS
use CGI qw ( -utf8 );
use C4::Auth;
use C4::Output;
my $query = new CGI;
my ($template, $borrowernumber, $cookie)
= get_template_and_user(
{
template_name => "opac-main.tt",
query => $query,
type => "opac",
authnotrequired => 0,
flagsrequired => { catalogue => '*', tools => 'import_patrons' },
}
);
output_html_with_http_headers $query, $cookie, $template->output;
=head1 DESCRIPTION
The main function of this module is to provide
authentification. However the get_template_and_user function has
been provided so that a users login information is passed along
automatically. This gets loaded into the template.
=head1 FUNCTIONS
=head2 get_template_and_user
my ($template, $borrowernumber, $cookie)
= get_template_and_user(
{
template_name => "opac-main.tt",
query => $query,
type => "opac",
authnotrequired => 0,
flagsrequired => { catalogue => '*', tools => 'import_patrons' },
}
);
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.

=head2 checkauth
($userid, $cookie, $sessionID) = &checkauth($query, $noauth, $flagsrequired, $type);
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.
Koha also has a concept of sub-permissions, also known as
granular permissions. This makes the value of each key
in the C<flagsrequired> hash take on an additional
meaning, i.e.,
1
The user must have access to all subfunctions of the module
specified by the hash key.
*
The user must have access to at least one subfunction of the module
specified by the hash key.
specific permission, e.g., 'export_catalog'
The user must have access to the specific subfunction list, which
must correspond to a row in the permissions table.
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.
