About Configuring SSSE for Multiple Active Directory Forest Environments

SSSE provides support for Microsoft Exchange environments that include more than one Active Directory forest, provided you enable SSSE to use fully qualified email addresses. For information on using fully qualified email addresses with SSSE, see Using Fully Qualified Email Addresses.

The Exchange Connector acts as an intermediary for all communications between the PIMSI engine and the Exchange Server. The Exchange Connector runs using the credentials of a specific user account that has access to the mailboxes of Active Directory (AD) users who have been enabled for synchronization.

The Siebel Server or Servers on which the PIMSI Dispatcher and the PIMSI Engine are located can be in a different AD forest to the domain in which the Exchange Connector(s) server is located, provided there is a trust relationship between the domains. Each Exchange Connector can also reside in a different AD forest to any other Exchange Connectors. If an Exchange Connector is configured to process communications with a specific Microsoft Exchange Server, the Exchange Connector must run as a user account in the same domain as the Microsoft Exchange Server, or in a domain that is a trusted domain of the Microsoft Exchange Server.

Figure 4 illustrates the SSSE multiforest architecture (each domain is in a separate AD forest).

Requirements for Using SSSE with Multiple Active Directory Forests

To run SSSE in a multiple AD forest Microsoft Exchange environment, the following requirements must exist:

• You must be using Microsoft Exchange 2003 SP1 or later, or Microsoft Exchange 2007 or later
• There must be a trust relationship between the domain in which the Siebel Servers run (for example, Domain_A) and each of the other domains (for example, Domain_B and Domain_C). There does not necessarily have to be a trust relationship between the other domains, that is, between Domain_B and Domain_C, each of which contains an Exchange Connector and Exchange Server.
