You can create multiple authentication realms on your application
server. For each authentication realm that you create, you must also
create a corresponding directory configuration in Content Platform Engine so that the users and
groups in the authentication realm can be authorized.
About this task
Content Platform Engine requires
that all directory services be accessible at runtime. If one becomes
inaccessible,
Content Platform Engine will
not function correctly, even though other directory services are still
running. For example, if a system is configured for dc1.com and dc2.com,
and dc1.com becomes unavailable, then all users, including the users
in dc2.com, will be unable to access
FileNet P8. It is therefore a best
practice to configure LDAP failover for each directory service.
