Configuring Stateful Kerberos Authentication
The Stateful Kerberos Authentication profile requires that you specify a server group which includes the Kerberos
servers and the role to be assigned to users who are successfully authenticated. For details on defining a windows
server used for Kerberos authentication, see "Configuring a Windows Server" on page 174.
When the user logs off or shuts down the client machine, the user remains in the authenticated role until the user
ages out, that is, until the user has sent no traffic for the amount of time specified in the User Idle Timeout setting
in the Configuration > Security > Authentication > Advanced page.
