Configure the default referral to point to a Directory Server that has more information about the distribution of the directory service. Default referrals for the server are set by the nsslapd-referralattribute. Default referrals for each database in the directory installation are set by the nsslapd-referralattribute in the database entry in the configuration. These attribute values are stored in the dse.ldif file.

For information on configuring default referrals, refer to the HP-UX Directory Server administrator guide.

5.3.1.3 Smart referrals

The Directory Server can also use smart referrals. Smart referrals associate a directory entry or directory tree to a specific LDAP URL. This means that requests can be forwarded to any of the following:

•The same namespace contained on a different server.

•Different namespaces on a local server.

•Different namespaces on the same server.

Unlike default referrals, smart referrals are stored within the directory service itself. For information on configuring and managing smart referrals, see the HP-UX Directory Server administrator guide.

For example, the directory service for the American office of the Example Corp. contains the ou=people,dc=example,dc=com directory branch point.

Redirect all requests on this branch to the ou=people branch of the European office of Example Corp. by specifying a smart referral on the ou=people entry itself. The smart referral is ldap://europe.example.com:389/ou=people,dc=example,dc=com.

Any requests made to the people branch of the American directory service are redirected to the European directory. This is illustrated below:
