Configures the service console user authentication options including NIS, LDAP, Kerberos and Active Directory. In the following command, we are configuring authentication for the Active Directory domain called taupoconsulting.com[root@esx1host root]# esxcfg-auth –enablead –addomain=taupoconsulting.com –adddc=dc1.taupoconsulting.comYou can also use this tool to set a password policy for service console user accounts.[root@esx1host root]# esxcfg-auth –maxpassdays=90 –minpassdays=30 –passwarnage=75

In the above example, your service console user account password would expire after 90 days, you would get a warning message after 75 and once changed, you would have to keep that password for a minimum period of 30 days.
