To achieve the merger of the two data sets, create proxy transformations that map the Sample Corporation's source attributes to Example.com target attributes.
The Example.com schema already defines an attribute to contain the relative distinguished
name (RDN) of user entries, called uid. However, Example.com chooses to
create two new attributes within its exampleAccount object class to
accommodate two attributes in the Sample Corporation schema for representing the region and
the distinguished name (DN) of linked accounts.
During the merger, Example.com decides to re-parent the Sample Corporation's customer
entries, which are defined under two different subtrees, ou=east,o=sample
and ou=west,o=sample, placing them under Example.com’s
ou=people,dc=example,dc=com subtree. Associated proxy
transformations are described in the DN Mappings table below. In this process, Example.com
collapses the Sample Corporation tree, moving entries from the east and west region under a
single DN, dc=example,dc=com. The DN proxy transformations assume that all
the Sample Corporation users have been co-located under this single Example.com
subtree.
| Sample Attribute | Example.com Attribute | Description |
|---|---|---|
|
|
|
RDN of user entries |
|
|
|
String value representing the region |
|
|
|
DN value |
Legacy Sample LDAP applications searching for entries in either the Sample Corporation base DN ou=east,o=sample or ou=west,o=sample will be successfully serviced, though there will be one or more differences in the user entries seen by the Sample Corporation legacy applications.
Because the Example.com Directory Server has no knowledge of
the Sample Corporation user’s former ou=east or ou=west
association, search results for client searching under o=sample will
return a DN that might differ from the original search base. For instance, a search for
sampleID=abc123 under ou=west,o=sample might return
the user entry for abc123 with the DN of
sampleID=abc123,ou=east,o=sample.
The following table illustrates the mapping DNs.
