Frédéric Demians 1bf7550a82 Bug 7026 Web installer does not switch language 
Language installer should switch to template files of language selected in
first step. It used to do that, but the feature seems to be broken now. Web
installer remains English after selecting a different language.

To reproduce:

- make sure your database is empty
- run 'perl translate install <some language>
- access web installer
- select language other then en on the first page

=> templates should change to translated templates

Signed-off-by: Katrin Fischer <Katrin.Fischer.83@web.de>

Test plan provided works, correct language and sample files are selected.

In a second test I deleted the staff templates for de-DE and repeated
the steps. de-DE is not offered in the language selection of the web installer
now, but does appear in the opaclanguages list after running the web installer.
(Bug 5660)

=head1 NAME
InstallAuth - Authenticates Koha users for Install process
=head1 SYNOPSIS
use CGI;
use InstallAuth;
use C4::Output;
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},
});
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.
This package is different from C4::Auth in so far as
C4::Auth uses many preferences which are supposed NOT to be obtainable when installing the database.
As in C4::Auth, Authentication is based on cookies.

= 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
Templates.pm module.

=item 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.
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.
