Test, validate and match regular expressions
This regex parses LDIF entries from one directory service (DS A) to extract key attributes such as CN, OU, domain components, description, displayName, hwObjectGUID, extensionAttribute7, mail, and objectClass. It is designed to handle the specific tab-delimited formatting of LDIF lines, enabling the transformation and migration of directory data into another directory service (DS B). Use cases include automated LDIF conversion, data cleanup, and mass attribute extraction during directory migrations.
