Both sponsor and administrator account permissions are assigned using admin profiles. An admin profile is a set of permissions that defines what actions an administrator or a sponsor can perform on FortiAuthenticator. An admin profile can be assigned to an admin group or an individual admin user. A sponsor is a special type of admin user who can create and manage guest accounts on behalf of other users.

 To enable guest portal services on FortiAuthenticator, you need to configure a portal policy that defines the conditions for presenting the guest portal to users and the authentication methods to use. You also need to configure at least one post-login service that defines what actions to take after a user logs in successfully, such as sending an email confirmation, assigning a VLAN, or creating a user account. Configuring a RADIUS client or an external authentication portal are optional steps that depend on your network setup and requirements.

Online activation of the tokens through the FortiGuard network is the most secure way of delivering FortiToken data once the token has been seeded because it eliminates the risk of seed files being compromised during transit or storage. The other methods involve physical or manual delivery of seed files which can be intercepted, lost, or stolen.

Adaptive Authentication is a feature that allows administrators to bypass the need for two-factor authentication for users accessing from specific secured networks. Adaptive Authentication uses geolocation information from IP addresses to determine whether a user is accessing from a trusted network or not. If the user is accessing from a trusted network, FortiAuthenticator can skip the second factor of authentication and grant access based on the first factor only.

When deploying FortiAuthenticator for portal services, such as guest portal, sponsor portal, user portal or FortiToken activation portal, the network configuration must allow specific ports to be open between FortiAuthenticator and the authentication clients. These ports are:

TCP 80 for HTTP access

TCP 443 for HTTPS access

TCP 389 for LDAP access

TCP 636 for LDAPS access

UDP 1812 for RADIUS authentication

UDP 1813 for RADIUS accounting

Guest accounts are associated with the sponsor that creates the guest account. A sponsor is a user who has permission to create and manage guest accounts on behalf of other users3. A sponsor can create guest accounts using the sponsor portal or the REST API3. The sponsor’s username is recorded as a field in the guest account’s profile3.

FortiAuthenticator is a user and identity management solution that provides strong authentication, wireless 802.1X authentication, certificate management, RADIUS AAA (authentication, authorization, and accounting), and Fortinet Single Sign-On (FSSO). It also offers portal services for guest management, self-service password reset, and device registration. It is not a log server or an RSSO server.

To monitor FortiAuthenticator system information and receive FortiAuthenticator traps through SNMP, two configurations must be performed after enabling SNMP access on the FortiAuthenticator interface:

Set the thresholds to trigger SNMP traps for various system events, such as CPU usage, disk usage, memory usage, or temperature.

Upload management information base (MIB) files to SNMP server to enable the server to interpret the SNMP traps sent by FortiAuthenticator.

The screenshot shows that the account registration feature is enabled for the guest portal and that the guest group is set to Guest_Portal_Users. This means that all guest accounts created using this feature will be placed under that group1. The screenshot also shows that email validation is enabled for the guest portal and that the email validation link expires after 24 hours. This means that all accounts registered through the guest portal must be validated through email within that time frame1.

FortiAuthenticator can be configured as a SAML identity provider (IdP) or a SAML service provider (SP). As an IdP, FortiAuthenticator authenticates users and issues SAML assertions to SPs. As an SP, FortiAuthenticator receives SAML assertions from IdPs and grants access to users based on the attributes in the assertions. Principal and assertion server are not valid SAML roles.
