You can use an LDAP data object read operation to look up data in an LDAP object. You add an LDAP data object read operation to a mapping as an LDAP lookup. You can look up data from LDAP in a mapping based on a lookup condition.
For example, you can look up the profile details of the user object when you add the LDAP data object read operation as a lookup in a mapping. The Data Integration Service queries the lookup source based on the properties and conditions that you specify in the LDAP lookup.
