By encapsulating this information into a Controller Service and allowing other components to make use of it (as opposed to specifying the principal and keytab directly in the processor) an administrator is able to choose which users are allowed to use which keytabs and principals. This provides a more robust security model for multi-tenant use cases.</description><tags><tag>Kerberos</tag><tag>Keytab</tag><tag>Principal</tag><tag>Credentials</tag><tag>Authentication</tag><tag>Security</tag></tags><properties><property><name>Kerberos Keytab</name><displayName>Kerberos Keytab</displayName><description>Kerberos keytab associated with the principal.
