Note: The default admin account is always authenticated locally, regardless of the
authentication method setting. (See Chapter 37 on page 573 for more
information about authentication methods.)
Ext-User Accounts
Set up an ext-user account if the user is authenticated by an external server and
you want to set up specific policies for this user in the ZyWALL. If you do not want
to set up policies for this user, you do not have to set up an ext-user account.
All ext-user users should be authenticated by an external server, such as AD,
LDAP or RADIUS. If the ZyWALL tries to use the local database to authenticate an
ext-user, the authentication attempt always fails. (This is related to AAA servers
and authentication methods, which are discussed in Chapter 37 on page 573 and
Chapter 38 on page 583, respectively.)
Note: If the ZyWALL tries to authenticate an ext-user using the local database, the
attempt always fails.
Once an ext-user user has been authenticated, the ZyWALL tries to get the user
type (see Table 151 on page 539) from the external server. If the external server
does not have the information, the ZyWALL sets the user type for this session to
User.
For the rest of the user attributes, such as reauthentication time, the ZyWALL
checks the following places, in order.
1 User account in the remote server.
2 User account (Ext-User) in the ZyWALL.
3 Default user account for AD users (ad-users), LDAP users (ldap-users) or
RADIUS users (radius-users) in the ZyWALL.
