Example 2 — User Login with inetCanonicalDomainName

Assume the two organization nodes, o=sesta and o=sesta2, are decorated as shown in Example 1. The user jdoe logs in to Messaging Server with the following user ID:

jdoe@sesta2.com

In this example, there can be only one LDAP entry for the user jdoe.

In this case, Messaging Server performs one or more lookups to determine jdoe's canonical user ID, which consists of the user's uid followed by @ and the user's canonical domain name.

Messaging Server looks up the value of the inetCanonicalDomainName attribute in the sesta2 organization entry. It then replaces the original domain name in the login ID, sesta2, with the canonical domain name, sesta.

Using the canonical user ID, Messaging Server opens jdoe's correct mailbox, which displays all of jdoe's messages, including messages sent to jdoe@sesta2.com, to jdoe@sesta.com, and to any other domain or alias domain associated with jdoe.
