Authentication
214 IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0
Authentication
In the Authentication window, you can select up to two methods of authentication made up of
external authentication options and/or the local user database.
Configure the following parameters:
Primary
Authentication
Method
Secondary
Authentication
Method
Settings Button
Only use as backup
Only authenticate
admin user in the
local database
The first authentication method that the IOLAN attempts.
Data Options: Local, RADIUS, Kerberos, LDAP, TACACS+, SecurID, NIS
Default: Local
If the Primary Authentication Method fails, the next authentication method
that the IOLAN attempts. You can choose to use authentication methods in
combination. For example, you can specify the
Primary Authentication
Method
as Local and the Secondary Authentication Method as RADIUS.
Therefore, some users can be defined in the IOLAN (
Local) others in RADIUS.
Data Options: None, Local, RADIUS, Kerberos, LDAP, TACACS+, SecurID,
NIS
Default: None
Click this button to configure the authentication method.
The secondary authentication method will be tried only when the IOLAN
cannot communicate with the primary authentication host.
Default: Disabled
When enabled, the IOLAN will only authenticate the admin user in the local
user database, regardless of any external authentication methods configured.
When disabled, a user called admin must exist when only external
authentication methods are configured, or you will not be able to access the
IOLAN as the admin user, except through the console port.
Default: Enabled
