Destroy the Kerberos services (KDC, Administration server, and Password server).
Stop the daemon (krb5kdc, kadmind, or kpasswdd)
Destroy the service object as follows:
kdb5_util [-D user_dn [-w passwd]] [-h ldap_server] [-p ldap_port] [-t trusted_cert] destroy_service [-f stashfilename] service_dn
For example:
kdb5_util -D cn=admin,o=mit -w secret destroy_service -f /usr/local/var/krb5kdc/servicepasswd cn=kdc-service,o=mit
IMPORTANT: If you destroy a Kerberos service without stopping the daemon, the service still continues to service the incoming requests, as it has an active connection with the LDAP server.
