How to Manually Propagate the Kerberos Database to the Slave KDCs

  1. Become superuser on the master KDC.
  2. (Optional) Back up the database by using the kdb5_util command. # /usr/sbin/kdb5_util dump /var/krb5/slave_datatrans.
  3. Propagate the database to a slave KDC by using the kprop command.

Is Kerberos still used today?

Is Kerberos Obsolete? Kerberos is far from obsolete and has proven itself an adequate security-access control protocol, despite attackers’ ability to crack it. The primary advantage of Kerberos is the ability to use strong encryption algorithms to protect passwords and authentication tickets.
