The same mechanism can be used to redirect queries to a different server that uses a different namespace. For example, an employee working in the Italian office of Example Corp. makes a request to the European directory service for the phone number of an Example Corp. employee in America. The directory service returns the referral

ldap://europe.example.com:389/ou=US employees,dc=example,dc=com.

Figure 5-8 Redirecting a query to a different server and namespace

Finally, if multiple suffixes are served on the same server, queries can be redirected from one namespace to another namespace served on the same machine. For example, to redirect all queries on the local machine for o=example,c=us to dc=example,dc=com, then put the smart referral ldap:///dc=example, dc=com on the o=example,c=us entry.

NOTE:

The third slash in this LDAP URL indicates that the URL points to the same Directory Server.

Creating a referral from one namespace to another works only for clients whose searches are based at that distinguished name. Other kinds of operations, such as searches below ou=people,o=example,c=US, are not performed correctly.

For more information on LDAP URLS and on how to include smart URLs on Directory Server entries, see the HP-UX Directory Server administrator guide.
