**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.
<code>
 samba-tool spn add host/fdqn@KerberosRealm sAMAccount
</code>

To then generate a keytab for that principle again using the "samba-tool" run the following:
<code>
 samba-tool domain exportkeytab  name.keytab  --principal=host/fdqn@KerberosRealm
</code>

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.
