Check that SSSD-generated kdcinfo has IPv6 only addresses in
/var/lib/sss/pubconf/. If not, you need to set

lookup_family_order = ipv6_only

in the domain section in sssd.conf (it defaults to ipv4_first) and
restart sssd.
Thank you a lot. This suggestion did the trick and now working nicely.

Regards,
William
