P6 Professional provides support for the following authentication modes to validate user logins.
- Native: Native mode is the default user authentication scheme for all Oracle Primavera P6 Professional applications. When a user attempts to log on to a Primavera application, native mode confirms the user’s identity in the database.
- LDAP (Lightweight Directory Access Protocol): LDAP mode confirms a user's identity in the designated directory server database when a user attempts to log on to an application.
