About Windows Authentication
The Windows Authentication feature allows your users to log in to the Email
Continuity portal using their regular network passwords. To accomplish this, an
Authentication Manager installed on a local machine in your environment
validates a user’s credentials with the local Windows subsystem using New
Technology LAN Manager (NTLM). If the user’s credentials are correct according
to the local Windows subsystem, the Authentication Manager reports this to the
data center, and the user is allowed to log in to the Email Continuity portal.
MessageLabs does not synchronize users’ passwords from Active Directory.
If the Windows subsystem determines the login credentials are invalid, Email
Continuity (and Windows, if applicable) increments the failed login count by one,
and access to Email Continuity is denied.
