Note: When using Microsoft Active Directory for authentication, Kerberos keys are managed automatically. For other directory servers, it's necessary to import keytabs manually.
A Kerberos keytab is a file that contains pairs of Kerberos principals and encrypted keys. By importing and using Kerberos keytabs, The Smoothwall services, such as authentication, can use the interoperability features provided by Kerberos.
To generate keytabs, refer to the documentation delivered with your directory server.
To understand more about how to get a keytab from Active Directory, see Microsoft support documentation, http://technet.microsoft.com/en-us/library/cc753771%28v=WS.10%29.aspx.
To create authentication policies using Kerberos as the authentication method, see the help topic, Creating authentication policies.
Kerberos keytabs are turned on by default. You can turn off a Kerberos keytab, for example, when troubleshooting.
