In order to implement the Resource Kit, a mail server is required. It is required for things such as events from an Identity Manager driver policy, password change notification, or workflow events for the Identity Manager User Application.
Instead of setting up a complete e-mail server, the Resource Kit has a secure mail relay that allows an authorized Identity Manager User Application user to send e-mail when required. The secure mail relay uses the postfix smtpd MTA agent as a secure e-mail relay with cyrus-sasl-sasauthd, using LDAP authentication against eDirectory™ for smtp_auth.
To set up a secure mail relay, the Server Base System install for SUSE® Linux Enterprise Server (SLES) 10 SP2 needs to contain cyrus-sasl, cyrus-sasl-saslauthd, and postfix. If you followed the steps in Identity Manager Resource Kit 1.2 Installation Guide for SUSE Linux Enterprise Server 10 SP2, these options were installed.
