Chapter 44 User/Group
Note: The default admin account is always authenticated locally, regardless of the
authentication method setting. (See
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 ISG50. 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 ISG50 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 48 on page 631
Note: If the ISG50 tries to authenticate an ext-user using the local database, the
attempt always fails.
Once an ext-user user has been authenticated, the ISG50 tries to get the user type (see
on page 599) from the external server. If the external server does not have the information, the
ISG50 sets the user type for this session to User.
For the rest of the user attributes, such as reauthentication time, the ISG50 checks the following
places, in order.
User account in the remote server.
1
User account (Ext-User) in the ISG50.
2
Default user account for AD users (ad-users), LDAP users (ldap-users) or RADIUS users (radius-
3
users) in the ISG50.
See Setting up User Attributes in an External Server on page 610
set up the attributes in an external server.
Ext-Group-User Accounts
Ext-Group-User accounts work are similar to ext-user accounts but allow you to group users by
the value of the group membership attribute configured for the AD or LDAP server. See
48.2.1 on page 635
User Groups
User groups may consist of user accounts or other user groups. Use user groups when you want to
create the same rule for several user accounts, instead of creating separate rules for each one.
Note: You cannot put access users and admin users in the same user group.
Note: You cannot put the default admin account into any user group.
The sequence of members in a user group is not important.
