Hi there ip-rob.
Thanks for your post.
I, however, would like to know how did you manage to make the ldap bind against the AD. I know on the configuration side of the ADI plug in, there is nothing else I should look up. But maybe on the PHP LDAP on the WordPress installation or on the server side of the AD.
I have my AD running on windows 2008 R2 server standard. Im using a self signed certificate and many tools I am using are successfully authenticating against this server using LDAP over SSL (ldaps)
Can you help?
