Hello all,
Apologies for the necromancy here, but there seems to be conflicting information regarding group enumeration within an IPA AD Trust, specifically, these tidbits:

According to this thread and its linked bug reports, this was addressed in SSSD versions >= 1.14.0-43. But, per the URL https://access.redhat.com/solutions/3597701 the following is stated:
"Enumeration is not supported in IPA-AD trust environments." "This is an expected behaviour if SSSD is not enumerating all AD users/groups on IPA server or client after setting enumerate = True and subdomain_enumerate = True in sssd.conf."
&
"Enumeration' is not supported in IPA-AD trust environments. As per confirmation from IPA/SSSD engineering team, there is no plan on supporting enumeration with IPA-AD trusts as it just wouldn't scale with large AD domains."
Our AD domain does permit enumeration as the sssd_nss.log on the IPA master didn't manifest a message stating that the domain does not support enumeration.
Given the aforementioned information, is it correct to assume that current versions of SSSD and IPA do not support enumerating a group which contains trusted AD users who haven't logged in before/been queried via `groups`, `id`, or `getent passwd`?
This is confusing because the enumerate word is overloaded :-)
What is not supported and I guess won't be is "getent passwd" or "getent group" to get all objects from AD. What is supported since 1.14 was to get AD members of an IPA group added through an external group, e.g. "getent group ipagroup" should show both its IPA and AD group members.
