[Freeipa-users] HBAC access denied, all AD groups not detected

[Lachlan Musicman]

FWIW,

We are seeing the issues that are described here:

https://www.redhat.com/archives/freeipa-users/2015-December/msg00046.html

I was about to write when I found this, it explains exactly what I am
seeing - right down to the "impossible to reproduce because it's so
(seemingly) random".


I am about to read up on the SSSD trouble shooting in order to up the logs
&etc, but here is some output I can share - note that this all happened in
~5 minutes. As you can see, clearing the cache has various unpredictable
effects. Both users should return the same list of groups. This was
performed on a FreeIPA client.
