Answer 1

My 2 cents: on server side, disable GSSAPIAuthentication (i.e. SSO backed by Kerberos) unless you are using Active Directory authentication on Linux (with either Centrify or SSSD) inside a corporate firewall.

If you are indeed in a SSO scenario, but Single Sign-On does not work out of the box for some reason, then use client-side options to bypass Kerberos e.g.

ssh -o GSSAPIAuthentication=no -o GSSAPIKeyExchange=no
