No idea, we do not produce sssd, can I suggest asking on the sssd-users mailing list. Rowland

And can you run "kinit" to ensure you have a valid ticket? One of my favorite failures is when the time settings between the local host, and the Samba or AD server, have drifted from each other. There are a lot of very awkward and inconsistent NTP or chronyd settings out there, exacerbated when people point NTP to only one server and that server is inaccessible to one or more hosts.> > I must precise we use pam_sssd against Samba4/AD to authenticate. > > Here is my /etc/sssd/sssd.conf: > > > Hmm, I wonder if sssd is getting in the way ?

They try to hide a lot of steps away from the user, but the internal interactions are a bit of a "mousetrap" game. When it works, you get the mouse. But if any of the many steps are even slightly worn, it becomes erratic or fails.
