Mastering Active Directory - Second Edition

The ntds.dit file

This is the actual AD database file. This database contains three main tables. The schema table includes data regarding the object classes, attributes, and the relationship between them. The link table includes data about values referring to another object. Group membership details are a good example of this. The data table includes all the data about users, groups, and any other data integrated with AD. In the table, rows represent the objects and columns represent the attributes.
