David Cook 331af8521b Bug 13779: sessionID declared twice in C4::Auth::checkauth() 
The bug is that $sessionID is declared twice in C4::Auth::checkauth().
At the moment, this doesn't actually create a problem, because no
one seems to be using the $sessionID which is returned by checkauth(),
except in the case of opac/external/overdrive/auth.pl which skips
the second declartion as it doesn't require auth.

This patch removes the redefining of the $sessionID variable.

In terms of testing, try logging in with a username and password
and see if it works. The only risk this patch would pose is breaking
auth I would think, since nothing is actually using the return value
from checkauth() for $sessionID.

NOTE:
It was initially defined near the top of the function (~line 791).
I believe the scoping would mean the correct version of $sessionID
would be used in the latter lines for the unset'ing.
I have skimmed code to see if the sessionID return value is used.
I did not test overdrive, as I do not know how. However, this is
the only area, I think this could possibly break. This change makes
sense to me.

QA: Please test overdrive.
opac/external/overdrive/auth.pl only checks if the value is set, so
   this patch might fix/break something there?
opac/svc/overdrive same kind of check.

This is a (tiny) code improvement. Now we consistently return the session
id that is also stored in the returned cookie. (Which can be an 'anon'
session.)
Fact is that Koha almost everywhere ignores the returned session id and
sometimes gets the session from the cookie (obviously). The session id is
also passed to the template by get_template_and_user but never used in
templates.
As mentioned, the two overdrive scripts are the exception. But since both
test on both $user && $sessionID, they will not choke on an anynonomous
session id without userid. So theoretically fine, but not tested.

=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 logged_in_user variable (which is a Koha::Patron object). 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.

cookie, determine if the user has the privileges specified by C<$userflags>.
C<check_api_auth> is is meant for authenticating users of web services, and
consequently will always return and will not attempt to redirect the user
agent.
If a valid session cookie is already present, check_api_auth will return a status
of "ok", the cookie, and the Koha session ID.
If no session cookie is present, check_api_auth will check the 'userid' and 'password
parameters and create a session cookie and Koha session if the supplied credentials
are OK.
Possible return values in C<$status> are:

=item "failed" -- credentials are not correct; C<$cookie> and C<$sessionid> are undef
