Just another thing to make sure is correct: edit the user store in User admin tool. Is the ID provider field set to the new provider you’ve installed? Or else the default XP one is used.
What does your logs say? And are you sure the xp instance can access the ldap server?
Server logs does not say anything. No information related to this when I try to log in with an AD user.
Is there another log level I could use to get more information in the log?
(I can browse AD with ldap browser from the xp server)

I created a new user store and selected the LDAP id provider application. I also get the login screen from this app when I change the vhost config to use this userstore so it seems ok.
But I wanted to add because it happened to me last time: since you are using AD, change the “LDAP Dialect” from “Generic” to "Active Directory"
I changed it to active directory as well but no luck.
