When you select this from the Options menu, Leash will display a
tabbed window. The box within this window has four tabs:
Default Realm Configuration:
There are two groups, the Kerberos Realm/Host Server and the Computer Host/Domain Name.
Kerberos Realm/Host Server: In the Your Kerberos Realm field, select a Kerberos realm from the dropdown list. The list is editable using the Realm/Server Mapping tab. Leash automatically fills in your Kerberos server with the first server in the "Servers Hosting a KDC" list on the Realm/Server Mappings tab.
Computer Host/Domain Name: The field labeled Your Computer's Host Name displays
the name of your local machine. The Your Computer's Domain Name field
displays the domain to which your local machine currently belongs.
Ticket Lifetime:
There are two expiration times associated with Kerberos
tickets. The first specifies the length of the time period during
which the tickets are valid for use. The second specifies the
length of the renewable lifetime. Valid Kerberos tickets may have
their valid use lifetime repeatedly extended up until the renewable
lifetime expires. The settings on this page are used to configure
default lifetime values for Leash to use when requesting Kerberos
tickets from the Kerberos server (key distribution center). The
Kerberos server may issue tickets with shorter lifetimes than were
requested.
The minimum and maximum values are used by the ticket initialization
dialog box when constructing the Lifetime and Renewable Lifetime
sliders. These sliders can be used to modify the requested ticket
lifetimes when Kerberos tickets are initialized.
Realm/Server Mapping:
DNS/Realm Mapping:
Each entry here consists of two portions: the domain name (such as .mit.edu) or hostname (such as dialup.athena.mit.edu) followed by a space and the Kerberos realm (such as ATHENA.MIT.EDU) which is used by that domain or machine. You can insert new entries, edit existing ones, or delete old entries.
