FAQ’s on DeploymentThis section provides answers to some frequently asked questions.
What is the purpose of Single Sign-on?
Single Sign-on is required to seemlessly interoperate between calendar, address book, and mail.
When should I use Messaging Single Sign-On?
If the Messaging Server has already been setup to use Sun Java System LDAP Schema1 without Access Manager support, enable Messaging Single Sign-On to authenticate.
To enable Single Sign-on in Communications Express using Messaging Single Sign-On, refer to the section on Setting up Messaging Single Sign-On, in Chapter 4 of this guide.
When should I use Identity Server Single Sign-On?
If you have an existing setup with Sun Java System LDAP Schema 2 configured, enable the Identity Server Single Sign-on.
To enable Single Sign-on in Communications Express using Identity Server Single Sign-On, refer to the section Setting up Identity Server Single Sign-On, in Chapter 4 of this guide.
What are the deployment requirements for Communications Express?
- If mail is enabled, Messenger Express should be installed and configured on the same host.
- If Access Manager is enabled, Install Access Manager on the same machine as Communications Express, or install Access Manager SDK and configure it to point to the remote Access Manager.
To configure remote Access Manager SDK, refer to the steps mentioned under the procedure To Deploy Identity Server and Communications Express in Different Web Container Instance in Chapter 4 of this guide.
Can PAB entries from an existing Messaging Server, for example, Messaging Server 5.2 or Messaging Server 6.0, be migrated to Communications Express?
Yes. Refer to Chapter 7, "Migrating PAB Data to Addressbook Server," for migration details.
Can any of the application in Communications Express be disabled?
You can disable Calendar and Mail application, but cannot disable the Address book Application.
