Authentication Modes
Authentication is the process of identifying a user or a server to the directory server and granting access to legitimate users based on user name and password information provided when users log in. VMware Zimbra Collaboration Server offers the following three authentication mechanisms:
*
Internal. The Internal authentication uses the Zimbra directory server for authentication on the domain. When you select Internal, no other configuration is required.
*
External LDAP. The user name and password is the authentication information supplied in the bind operation to the directory server. You must configure the LDAP URL, LDAP filter, and to use DN password to bind to the external server.
*
External Active Directory. The user name and password is the authentication information supplied to the Active Directory server. You identify the Active Directory domain name and URL.
On the administration console, you use an authentication wizard to configure the authentication settings on your domain.
