Kerberos clients need to send UDP and TCP packets on port 88 and receive replies from the Kerberos servers.

What is a Kerberos Keytab?

A keytab is a file containing pairs of Kerberos principals and encrypted keys (which are derived from the Kerberos password). … Keytab files are commonly used to allow scripts to automatically authenticate using Kerberos, without requiring human interaction or access to password stored in a plain-text file.
