M-Business Server supports external authentication of users by either NT domain controllers or a Lightweight Directory Access protocol (LDAP) server. With external user authentication, user IDs and passwords are maintained in the external system. This means that NT domain or LDAP user accounts are reused by M-Business Server.

The M-Business database then mirrors the user ID and password information in the external system. When a user password is changed in the external system, M-Business Server uses the new password automatically. Adding and deleting users is also handled by the external system.

• With NT domain integration, add and delete users from the User Manager for Domains (in NT) or from the Active Directory Users and Computers snap-in (in Windows 2000), not from the M-Business Server Administrator Console.
• With LDAP, you add and delete users from through the LDAP server instead of the M-Business Server Administrator Console.
