ESXI-67-000018 - The ESXi host SSH daemon must not permit GSSAPI authentication.

GSSAPI authentication is used to provide additional authentication mechanisms to applications. Allowing GSSAPI authentication through SSH exposes the system's GSSAPI to remote hosts, increasing the attack surface of the system.

From an SSH session connected to the ESXi host, or from the ESXi shell, add or correct the following line in '/etc/ssh/sshd_config':

GSSAPIAuthentication no
