Using a Correlation Rule
In a MetaLink agreement, correlation rules are used to link
entries in two directory servers. It is an important part of the
synchronization process, because it determines which entry in the
destination server corresponds to which entry in the source server.
entries in two directory servers. It is an important part of the
synchronization process, because it determines which entry in the
destination server corresponds to which entry in the source server.
Only one correlation rule needs to give a match for a destination
entry to correlate with a source entry. Each rule consists of at least
one attribute mapping, where each source and destination
attribute needs to be the same value in order for the rule to
correlate.

You can consider a correlation rule to be part of a logical OR
statement, and the attribute mappings within the correlation rule
part of a logical AND statement.

part of a logical AND statement.
A correlation rule accommodates both simple and complex
correlations. The directory server may have a natural correlator
(e.g. unique employee number) or a combination of correlators
(e.g. first name, last name, and department number) that establish
a correlation rule.

You can combine a number of correlation rules to create complex
rules which include logical AND operators, string constants and
equality tests.
rules which include logical AND operators, string constants and

It is important to consider which attributes to use when creating a
correlation rule. The value, or combination of values, must be
unique in both MeetingPlace and your corporate directory server.
If the value of these attributes is not unique, multiple entries
could correlate into a single entry. Also, the attributes used in the
correlation rule must exist in all entries in both MeetingPlace and
your corporate directory server.

Additionally, it is important to remember that if correlation can’t
be made between entries in MeetingPlace and your corporate
directory server, then a new entry will be created using BootStrap
attribute mapping. Therefore, a correlation rule must be defined
properly to ensure this doesn’t happen if there are corresponding
