Description

Krb5 Config uses a singleton and once initialized it does not refresh automatically. Without refresh, there are failures if you are using MiniKDCs with different configurations (such as different realms) within the same test run or if the Krb5 Config singleton is called before the MiniKDC is started for the first time.
