Configure the domain realm name, the key distribution centers for the realm, and the KDC timeout.
About this task
The realm is the name of an administrative entity that maintains authentication data. Selecting a descriptive name for the Kerberos authentication realm is important. Configure the realm, also known as the domain name, and the corresponding KDC service in Unified Access Gateway. When a UPN request comes to a specific realm, Unified Access Gateway internally resolves the KDC to use the Kerberos serviced ticket.
The convention is to make the realm name the same as your domain name, entered in uppercase letters. For example, a realm name is EXAMPLE.NET. The realm name is used by a Kerberos client to generate DNS names.
Starting with UAG 3.0, you can delete previously defined realms.
A server with Kerberos enabled with the realm names for the Key Distribution Centers to use identified.
