I've got a potential use case where I want to authenticate users using their AD credentials, store accounts and permissions in FreeIPA but not have a cross forest trust. One way to do this is to have SSSD talk LDAP to a virtual directory which would route the bind to AD but all other operations to the 389 backing IPA. Kerberos wouldn't work, but if you're interested in password or ssh key based auth it should work, right? Then you'd still get the HBAC benefits?
There is more than just look up in LDAP when talking to AD DCs. Trust ensures we have enough correctly set security descriptors on the objects we use to represent our identity to access AD DCs. If that part is missing, you get all kinds of problems.
Replacing trust by something that is effectively attempting to simulate trust but not being a trust scenario is, of course, possible. However, I don't see this as something we'd like to put any reasonable time to develop because it is a corner case with disproportional amount of development time investment. You may disagree and that's fine, but this doesn't change the fact that somebody needs to invest time into it. -- / Alexander Bokovoy -- Manage your subscription for the Freeipa-users mailing list: https://www.redhat.com/mailman/listinfo/freeipa-users Go to http://freeipa.org for more info on the project
