From http://wiki/deki-cp/authentication.php I learn that the domain URI is http://wiki/@api/deki/services/default/10 (and the SID is sid://mindtouch.com/2007/05/BETA/ldap-authentication) [strike]but when I try and open the URI I get the error "This error (HTTP 405 Method Not Allowed) means that Internet Explorer was able to connect to the website, but the site has a programming error."[/strike]
[Later] Once again, I'm proving I can't read. You said "append users/username". The results for that show an empty <group /> like tag.
- <user name="my_ad_shortname" displayname="Matt Wilkie">
<ldap-dn>CN=Matt.Wilkie,OU=users,OU=Environment,OU=Users and Groups,DC=DOMAIN,DC=ca</ldap-dn>
