34.1.2 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.
Ext-User users should be authenticated by an external server, such as 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 38 on page 531 and Chapter 39 on page 541, respectively.)
" 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 155 on page 503) 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 LDAP users (ldap-users) or RADIUS users (radius-users) in
the ZyWALL.
See Section 34.1.2.1 on page 504 for a list of attributes and how to set up the attributes in an
external server.
