Update Knowledge Base Pages affected by JOC-437 (Shiro Multi-Realm Handling)

Current Situation

• Shiro Multi-Realm Handling changes with Release 1.12.4 and, in particular, the use of alternative Shiro authentication strategies for combined ini and LDAP realms is not documented.

Changes Required

• Shiro Multi-Realm Handling should be added to the JOC Cockpit Authentication and Authorization articles.
• A matrix should be provided showing behaviour (i.e. are Authentication and Authorization successful in a mult-irealm environment?) for the different Shiro authentication strategies and the SOSFirstSuccessAuthenticator.
• Implicit & explicit realm ordering should also be documented.
