+
+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 $query->header(
+ -type => guesstype($template->output),
+ -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.

+ 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.

+=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.
