Cascading Authentication

When you specify multiple authentication mechanisms for a Caché Service, Caché uses cascading authentication to manage user access to the system. Caché attempts to authenticate using the specified mechanisms in turn until one succeeds or until they all fail. The cascade depends upon the particular scenario.

Scenario 1: A Password user exists in the Caché system.

1. Kerberos.

2. OS-based.

3. Caché Login

Scenario 2: An LDAP or Delegated user exists

• No other authentication mechanism is tried.

Scenario 3: User name does not exist in Caché System

1. LDAP.

2. Delegated.

3. Unauthenticated.
