Perfect

OK, pretty easy this one:

And then it finally gives up:

And then it confirms:

This is usually DNS. So, let's us a big hammer:

add:
ad_hostname server1.winnet.local
ad_server server1.winnet.local
to the domain/ section of sssd.conf
and sssd -i -d3 again

If still nothing please post outputs for:
host server1.winnet.local
ping server1
hostname -d
hostname -f
hostname -s

The log of the DC when you start sssd:
easier to start samba as:
samba -i -d3
and watch live

The contents of:
/etc/hosts
/etc/hostname

HTH,
Steve
