Destroy the Kerberos services (KDC, Administration server, and Password server).
Stop the daemon (krb5kdc, kadmind, or kpasswdd)
Destroy the service object as follows:
kdb5_ldap_util [-D user_dn] [-H ldapuri] [-t trusted_cert] destroy_service [-f stashfilename] service_dn
For example:
kdb5_ldap_util -D cn=admin,o=mit destroy_service -f /opt/novell/kerberos/keyfile cn=kdc-service,o=mit
IMPORTANT:If you destroy a Kerberos service without stopping the daemon, the service continues to serve the incoming requests because it has an active connection with the LDAP server.
