Chapter 35 User/Group

Table 170 Types of User Accounts (continued)

TYPE	ABILITIES	LOGIN METHOD(S)

guest	Access network services	WWW
ext-user	External user account	WWW

Note: The default admin account is always authenticated locally, regardless of the

authentication method setting. (See Chapter 39 on page 617 for more information about authentication methods.)

Ext-User Accounts

Set up an ext-useraccount 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-useraccount.

All ext-userusers 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 39 on page 617 and Chapter 40 on page 627, respectively.)

Note: If the ZyWALL tries to authenticate an ext-userusing the local database, the attempt always fails.

Once an ext-useruser has been authenticated, the ZyWALL tries to get the user type (see Table 170 on page 583) 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.

1User account in the remote server.

2User account (Ext-User) in the ZyWALL.

3Default user account for AD users (ad-users), LDAP users (ldap-users) or RADIUS users (radius-users) in the ZyWALL.
