The LDAP source and target definitions represent metadata for LDAP entries. An LDAP source or target definition can contain single-valued and multi-valued attributes. A single-valued attribute can store one value at a time, and a multi-valued attribute can store more than one value at a time.

A multi-group source or target contains groups for single-valued and multi-valued attributes. All the single-valued attributes are part of a single group that is the parent group. The multi-group source or target contains a group for each multi-valued attribute.

The first group in a multi-group source or target is a parent group for all the groups in that source or target. The other groups are child groups of the parent group.

When the PowerCenter Integration Service extracts data from the source or loads data into the target, it converts the data based on the datatypes associated with the source or the target.
