[pmwiki-users] Pubcookie & pmwiki

Hi Patrick, et al,
I've been poking at the PmWiki source code for a bit in trying to get
PubCookie to work with PmWiki.
Here's some of my discoveries... Any suggestions are appreciated.
My config.php has include_once=('scripts/httpauth.php');
I've placed some markers to log what's happening in some of the PmWiki php
files. I've put an .htaccess file that will redirect the user to the
pubcookie server, and once authentication is successful, the pubcookie
server will send a cookie to the requesting server and the PmWiki page
should show. At the moment it kinda works. I see an incomplete page, but
content is available. I'm not sure, but from what the page looks like, it
might have something to do with http versus https URL's (i.e. the top left
logo.gif is in http?) -- I'm tipped on this because of the missing logo
image. I'm unable to edit. Which might be a good thing.
The behaviour is that everytime a link is clicked, i'm redirected back to
the pubcookie server, then back to the wiki site. I looked at the
UserAuth code, and it seems to have some caching work there. Is caching
necessary for this to work?
The output to what the pubcookie server is forwarding is here:
[UNIQUE_ID] => some_pubcookie_unique_id
[HTTPS] => on
[HTTP_ACCEPT] => */*
[HTTP_ACCEPT_LANGUAGE] => en
[HTTP_ACCEPT_ENCODING] => gzip, deflate
[HTTP_COOKIE] => pubcookie_pre_s=XXXXXX; pubcookie_g=XXX
[HTTP_USER_AGENT] => Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en)
[HTTP_CONNECTION] => close
[HTTP_HOST] => host.utoronto.ca
[PATH] => /sbin:/usr/sbin:/bin:/usr/bin:/usr/X11R6/bin
[SERVER_SIGNATURE] => Apache/2.0.46 (Red Hat) Server at host.ns.utoronto.ca Port 443
[SERVER_NAME] => host.utoronto.ca
[SERVER_ADDR] => 192.168.0.1
[SERVER_PORT] => 443
[REMOTE_ADDR] => 192.168.0.2
[DOCUMENT_ROOT] => /pmwiki
[SERVER_ADMIN] => dky at utcc.utoronto.ca
[SCRIPT_FILENAME] => /pmwiki/index2.php
[REMOTE_PORT] => 64078
[REMOTE_USER] => userid
[AUTH_TYPE] => authUT
[GATEWAY_INTERFACE] => CGI/1.1
[SERVER_PROTOCOL] => HTTP/1.1
[REQUEST_METHOD] => GET
[REQUEST_URI] => /pmwiki/index2.php
[SCRIPT_NAME] => /pmwiki/index2.php
[PHP_SELF] => /pmwiki/index2.php
[PATH_TRANSLATED] => /pmwiki/index2.php
Using httpauth.php, it seems that PmWiki knows the $AuthId, however, no
$AuthFunction is defined.
$AuthId='userid from pubcookie server'
What $AuthFunction should PmWiki be using?
(maybe a new one, i.e. $AuthFunction='pubcookie'?)
Is there enough inside httpauth.php to make pubcookie work?
I looked at UserAuth/HtPasswd.php. I quite like how it works! I was
wondering if it's possible to use HtPasswd.php in some way to authorize
who has access (perhaps with read/edit/admin rights?) to the wiki?
if user_id exists in local/.htpasswd,
then allow access.
Once this works, i'd be happy to help document it. :-)
Many sincere thanks,
