**Adding SPN's and Generating keytabs** ====== Generating Keytabs ====== ---- Active directory requires kerberos service principle names to be mapped to a user account before a keytab can be generated. You can add spn names using the "samba-tool" provided with your Samba 4 installation. samba-tool spn add host/fdqn@KerberosRealm sAMAccount To then generate a keytab for that principle again using the "samba-tool" run the following: samba-tool domain exportkeytab name.keytab --principal=host/fdqn@KerberosRealm This should then produce the keytab for the principle that you have exported and this can then be copied to your target machine or service.
