Apache/AuthCookieNTLM version 0.06
==================================

As explained in the Apache::AuthenNTLM module, depending on the user's 
config, IE will supply your Windows logon credentials to the web server
when the server asks for NTLM authentication. This saves the user typing in
their windows login and password. 

Apache::AuthCookieNTLM is an interface to Shannon Peevey's 
Apache::AuthenNTLM module. The main aim is to authenticate a user 
using their Windows login and authenticating against the Windows
PDC, but to also store their login name into a cookie. This means
that it can be accessed from other pages and stops the system
having to authenticate for every request.

INSTALLATION

To install this module type the following:

=head1 NAME

Apache::AuthCookieNTLM - NTLM (Windows domain) authentication with cookies

=head1 SYNOPSIS

'WhatEver' should be replaced with the AuthName you choose
for this location's authentication.

    <Location />
        PerlAuthenHandler Apache::AuthCookieNTLM

        # NTLM CONFIG
        AuthType ntlm,basic
        AuthName WhatEver
        require valid-user

        #                   domain          pdc               bdc
        PerlAddVar ntdomain "name_domain1   name_of_pdc1"
        PerlAddVar ntdomain "other_domain   pdc_for_domain    bdc_for_domain"

=head1 DESCRIPTION

As explained in the Apache::AuthenNTLM module, depending on the user's 
config, IE will supply your Windows logon credentials to the web server
when the server asks for NTLM authentication. This saves the user typing in
their windows login and password. 

Apache::AuthCookieNTLM is an interface to Shannon Peevey's 
Apache::AuthenNTLM module. This modules authenticates a user 
using their Windows login against the Windows PDC, but to also 
stores their login name into a cookie. This means that it can be 
accessed from other pages and stops the system having to 
authenticate for every request.

We did consider using Apache::AuthCookie to store the details in a 
cookie but since using NTLM is basicaly there to remove the need
to login and is almost exclusively for intranets (as it needs access
to the PDC), we decided it was feasible not to use it.

=head1 APACHE CONFIGURATION

Please consult the Apache::AuthenNTLM documentation for more details on 
the NTLM configuration.

'WhatEver' should be replaced with the AuthName you choose
for this location's authentication.

=head2 PerlSetVar WhatEverName

Sets the cookie name. This will default to 
Apache::AuthCookieNTLM_WhatEver.

=head2 PerlSetVar WhatEverExpires 

Sets the cookie expiry time. This defaults to being 
a session only cookie.

=head2 PerlSetVar WhatEverPath

Sets the path that can retrieve the cookie. The default is /.

lib/Apache/AuthCookieNTLM.pm  view on Meta::CPAN


The method can be overwritten to set the values stored in the cookie

=head2 Example for overriding

This is an example of how to set your cookie values with whatever 
data you want.

  package MYAuthenNTLM;

  use Apache::AuthCookieNTLM;	
  use base ( 'Apache::AuthCookieNTLM' );
  use MyUserLookup_Package;
  
  sub choose_cookie_values {
    my ($self,$r) = @_;
	
    # Save if it's not already set
    if ($self->check_cookie()) {
		# Look up against other sources
	    my $person = MyUserLookup_Package->new($self->{'username'});

lib/Apache/AuthCookieNTLM.pm  view on Meta::CPAN

'Tools' -> 'Internet Options' -> 'Security' -> 'Local Intranet' ->
'Sites' -> 'Advanced' and add it in there, this must start
with http:// or https://

Once this is working you should be able to just replace

  PerlAuthenHandler Apache::AuthenNTLM

with		
		
  PerlAuthenHandler Apache::AuthCookieNTLM

And have it all just work[tm].

Remember to quit IE and reload as it's crap at implementing
changes on the fly!

=head2 Not setting cookies

IE doesn't seem to alert you (if you've turned prompt on 
for cookies). We guess it's because its from the trusted site.

=head2 access to /test failed in error log - but it works

Because Apache::AuthenNTLM has to go through several loops
the first of which will fail, this will be reported in
your error log, but you can just ignore it.
