Sounds good to me, I went to look at the mod_auth_tkt web site but
it seems to be down at the moment:
This is the wayback machines latest copy:
It looks like a cool module, nice that it does this:
4. Drop-in replacement for Basic Authentication: mod_auth_tkt sets
the Basic Authentication REMOTE_USER environment variable on
authorised requests, so that existing scripts that work with Basic
Authentication should work unchanged in a mod_auth_tkt environment.

Bruno might have some thoughts about the naming of perl modules and
at some point if probably makes sense to look at reorganising all
the naming and in the meantime your suggestion seems fine to me :-)
I'd be happy for this code to be in MKDoc perhaps the way it could
work is for there to be an option when a site is installed to
select cookie or httpd authentication (perhaps the default should
stay with http authentication)?
Or if mod_auth_tkt is installed and detected when the MKDoc site is
being installed then there could then be an option for cookie
authentication to be enabled?
Perhaps it might even be possible to offer HTTP authentication to
clients when cookie authentication is the default but the client's
browser is rejecting cookies? But if it isn't then this doesn't
If there is a variable that we can access in the templates based on
which authentication method is being used they we can serve a login
form via the login template fragment when it's needed for cookie

No problem :-)
The HTTP authentication support in 1.8 is a lot nicer than in 1.6,
only one domain is needed, you can login, logout and also login as
another user and do all this without restarting your web browser,
also there is an article about this here if people want to know how
it works (though it might be a bit out of date):
Some of the templates for the authentication need sorting out
though, by default the templates from the module on CPAN is used and
these don't match the new XHTML / CSS design. I'll look at fixing
this next week.
Another thing that would be good to have in the medium term is
support for HTTP digest authentication, there is this demo module
for doing it with apache 1.3 here:
But it seems that it would probably be better to wait for mod_perl 2
to become more stable, switch MKDoc to use apache 2.1 and then use
this module, it looks very cool:
One for the TODO list I think!
