Get the Kerberos ticket and authenticate Vertica

If your organization uses Kerberos as part of the login process, Kerberos tickets are automatically retrieved upon login. Otherwise, you need to run kinit to retrieve the Kerberos ticket.

The following example shows how to retrieve the ticket and authenticate Vertica Analytic Database with the KDC using the kinit command. EXAMPLE.COM is the realm name. You must use the realm name with your username to retrieve a Kerberos ticket. See Specify KDC information and configure realms.

$ kinit
Password for principal_user@EXAMPLE.COM: kpasswd

You are prompted for the password of the principal user name created when you created the principals and keytabs (see Create the Vertica principals and keytabs on Linux KDC).

The Kerberos ticket gets cached for a pre-determined length of time. See Ticket Management in the Kerberos documentation for more information on setting expiration parameters.

Upon expiration, you need to run the kinit command again to retrieve another Kerberos ticket.
