Fortinet Single Sign On – FortiAuthenticator 4.0

Fortinet Single Sign-On

FSSO is a set of methods to transparently authenticate users to FortiGate and FortiCache devices. This means that the FortiAuthenticator unit is trusting the implicit authentication of a different system, and using that to identify the user. FortiAuthenticator takes this framework and enhances it with several authentication methods:

Users can authenticate through a web portal and a set of embeddable widgets. l Users with FortiClient Endpoint Security installed can be automatically authenticated through the FortiClient SSO Mobility Agent.
Users authenticating against Active Directory can be automatically authenticated. l RADIUS Accounting packets can be used to trigger an FSSO authentication. l Users can be identified through the FortiAuthenticator API. This is useful for integration with third party systems.

The FortiAuthenticator unit must be configured to collect the relevant user logon data. After this basic configuration is complete, the various methods of collecting the log in information can be set up as needed.

Domain controller polling

When the FortiAuthenticator runs for the first time, it will poll the domain controller (DC) logs backwards until either the end of the log file or the logon timeout setting, whichever is reached first.

When the FortiAuthenticator is rebooted, the memory cache is written to the disk, then re-read at startup, allowing the previous state to be retained. Windows DC polling restarts on boot, then searches backwards in the DC log files until it reaches either the log that matches the last known serial number found in the login cache file, the log that is older than the last recorded read time, or the end of the log file, whichever is reached first.

The currently logged in FSSO users list is cached in memory and periodically written to disk. In an active-passive HA cluster, this file is synchronized to the slave device.

Windows management instrumentation polling

The FortiAuthenticator supports Windows Management Instrumentation (WMI) polling to detect workstation log off. This validates the currently logged on user for an IP address that has been discovered by the DC polling detection method.

Remote WMI access requires that the related ports are opened in the Windows firewall, and access to a domain account that belongs to the Domain Admin group.

To open ports in the Windows firewall in Windows 7, run gpedit.msc, go to Computerconfiguration >

Administrative Templates > Network > Network Connections > Windows Firewall > Domain Profile, go to Allow remote admin exception, then enable remote admin exception and, if necessary, configure an IP subnet/range.

General settings

The FortiAuthenticator unit listens for requests from authentication clients and can poll Windows Active Directory servers.

To configure FortiAuthenticator FSSO polling:

Go to Fortinet SSO Methods > SSO > General to open the Edit SSO Configuration The Edit SSO Configuration window contains sections for FortiGate, FSSO, and user group membership.
In the FortiGate section, configure the following settings:

Listening port	Leave at 8000 unless your network requires you to change this. Ensure this port is allowed through the firewall.
Enable authentication	Select to enable authentication, then enter a secret key, or password, in the Secret key field.
Login Expiry	The length of time, in minutes, that users can remain logged in before the system logs them off automatically. The default is 480 minutes (8 hours).
Extend user session beyond logoff by	The length of time, in seconds, that a user session is extended after the user logs off, from 0 (default) to 3600 seconds.
Enable NTLM authentication	Select to enable NTLM authentication, then enter the NETBIOS or DNS name of the domain that the login user belongs to in the Userdomain field.

In the Fortinet Single Sign-On (FSSO) section, configure the following settings:

Maximum concurrent user sessions

Enter the maximum number of concurrent FSSO login sessions a user is allowed to have. Use 0 for unlimited.

Select Configure Per User/Group to configure the maximum number of concurrent sessions for each user or group. See Fine-grained controls on page 112.

Log Level

Select one of Debug, Info, Warning, or Error as the minimum severity level of events to log from the drop- down list.

Select Download all logs to download all FSSO logs to your management computer.

General settings

Enable Windows Active

Directory domain controller polling

Select to enable Windows AD polling.

Select to enable polling additional logon events, including from devices using Kerberos authentication or from Mac OS X systems, and from event IDs 672, 680, 4776, and 4768.

Enable polling additional logon events

When additional active directory logon event IDs is enabled, event IDs 528, 540, and 4624 are also polled. These event are generated when a user attempts to access a domain service or resource. When a user logs off from the workstation, such an event will be generated.

Enter the additional logon event timeout time in the Additional logon event timeout field, from 1 to 480 minutes, with 5 minutes being the default time.

Note: After a user logs off, their SSO session will stay active for the above configured period of time. During this time, if another user changes to the previous user’s IP address, they may be able to bypass the necessary authentication. For this reason, it is strongly recommended that the timeout time be kept short.

Enable DNS

lookup to get IP

from workstation name

Select to use DNS lookup to get IP address information when an event contains only the workstation name.

This option is enabled by default.

Directly use domain DNS

suffix in lookup

Select to use the domain DNS suffix when doing a DNS lookup.

This option is disabled by default.

Enable reverse DNS lookup to get workstation name from IP

Select to enable reverse DNS lookup. Reverse DNS lookup is used when an event contains only an IP address and no workstation name.

This option is enabled by default.

Do one more DNS lookup to get full list of IPs after reverse lookup of workstation name

Reverse DNS lookup is used when an event contains only an IP address and no workstation name. Once the workstation name is determined, it is used in the DNS lookup again to get more complete IP address

information. This is useful in environments where workstations have multiple network interfaces.

This option is disabled by default.

Include account name ending

with $ (usually computer account)

Accounts that end in “$” used to exclusively denote computer accounts with

no actual user, but in some cases, valid accounts imported from dated systems can feature them.

This option is disabled by default.

Enable Radius Accounting SSO clients

Select to enable the detection of users sign-ons and sign- offs from incoming RADIUS accounting (Start, Stop, and Interim-Update) records.

Port Based Network Access Control – FortiAuthenticator 4.0

1 Reply

Port-based Network Access Control

Port-based Network Access Control (PNAC), or 802.1X, authentication requires a client, an authenticator, and an authentication server (such as a FortiAuthenticator device).

The client is a device that wants to connect to the network. The authenticator is simply a network device, such as a wireless access point or switch. The authentication server is usually a host that supports the RADIUS and EAP protocols.

The client is not allowed access to the network until the client’s identity has been validated and authorized. Using 802.1X authentication, the client provides credentials to the authenticator, which the authenticator forwards to the authentication server for verification. If the authentication server determines that the credentials are valid, the client device is allowed access to the network.

FortiAuthenticator supports several IEEE 802.1X EAP methods.

EAP

The FortiAuthenticator unit supports several IEEE 802.1X EAP methods. These include authentication methods most commonly used in WiFi networks.

EAP is defined in RFC 3748 and updated in RFC 5247. EAP does not include security for the conversation between the client and the authentication server, so it is usually used within a secure tunnel technology such as TLS, TTLS, or MS-CHAP.

The FortiAuthenticator unit supports the following EAP methods:

Method	Server Auth	Client Auth	Encryption	Native OS Support
PEAP (MSCHAPv2)	Yes	Yes	Yes	Windows XP, Vista, 7
EAP-TTLS	Yes	No	Yes	Windows Vista, 7
EAP-TLS	Yes	Yes	Yes	Windows (XP, 7), Mac OS X, iOS, Linux, Android
EAP-GTC	Yes	Yes	Yes	None (external supplicant required)

In addition to providing a channel for user authentication, EAP methods also provide certificate-based authentication of the server computer. EAP-TLS provides mutual authentication: the client and server authenticate each other using certificates. This is essential for authentication onto an enterprise network in a BYOD environment.

For successful EAP-TLS authentication, the user’s certificate must be bound to their account in Authentication >

UserManagement > Local Users (see Local users on page 58) and the relevant RADIUS client in Authentication > RADIUS Service > Clients (see RADIUS service on page 91) must permit that user to authenticate. By default, all local users can authenticate, but it is possible to limit authentication to specified user groups.

Port-based Network Access Control EAP

The FortiAuthenticator unit and EAP

A FortiAuthenticator unit delivers all of the authentication features required for a successful EAP-TLS deployment, including:

Certificate Management: create and revoke certificates as a CA. See Certificate Management on page 132.
Simple Certificate Enrollment Protocol (SCEP) Server: exchange a Certificate Signing Request (CSR) and the resulting signed certificate, simplifying the process of obtaining a device certificate.

FortiAuthenticator unit configuration

To configure the FortiAuthenticator unit, you need to:

Create a CA certificate for the FortiAuthenticator unit. See Certificate authorities on page 140.

Optionally, you can skip this step and use an external CA certificate instead. Go to Certificate Management > Certificate Authorities > Trusted CAs to import CA certificates. See Trusted CAs on page 147.

Create a server certificate for the FortiAuthenticator unit, using the CA certificate you created or imported in the preceding step. See End entities on page 133.
If you configure EAP-TTLS authentication, go to Authentication > RADIUS Service > EAP and configure the certificates for EAP. See Configuring certificates for EAP on page 102.
If SCEP will be used:
1. Configure an SMTP server to be used for sending SCEP notifications. Then configure the email service for the administrator to use the SMTP server that you created. See E-mail services on page 46.
2. Go to Certificate Management > SCEP > General and select Enable SCEP. Then select the CA certificate that you created or imported in Step 1 in the Default CA field and select OK. See SCEP on page 147.
Go to Authentication > Remote Auth. Servers > LDAP and add the remote LDAP server that contains your user database. See LDAP on page 88.
Import users from the remote LDAP server. You can choose which specific users will be permitted to authenticate. See Remote users on page 65.
Go to Authentication > RADIUS Service > Clients to add the FortiGate wireless controller as an authentication client. Be sure to select the type of EAP authentication you intend to use. See RADIUS service on page 91.

Configuring certificates for EAP

The FortiAuthenticator unit can authenticate itself to clients with a CA certificate.

Go to Certificate Management > Certificate Authorities > Trusted CAs to import the certificate you will use. See Trusted CAs on page 147.
Go to Authentication > RADIUS Service > EAP.
Select the EAP server certificate from the EAP ServerCertificate drop-down list.
Select the trusted CAs and local CAs to use for EAP authentication from their requisite lists.
Select OK to apply the settings.

Configuring switches and wireless controllers to use 802.1X authentication

The 802.1X configuration will be largely vendor dependent. The key requirements are:

Device self-enrollment Port-based Network Access Control

l RADIUS Server IP: This is the IP address of the FortiAuthenticator l Key: The preshared secret configured in the FortiAuthenticator authentication client settings l Authentication Port: By default, FortiAuthenticator listens for authentication requests on port 1812.

Device self-enrollment

Device certificate self-enrollment is a method for local and remote users to obtain certificates for their devices. It is primarily used in enabling EAP-TLS for BYOD. For example:

l A user brings their tablet to a BYOD organization. l They log in to the FortiAuthenticator unit and create a certificate for the device. l With their certificate, username, and password they can authenticate to gain access to the wireless network. l Without the certificate, they are unable to access the network.

To enable device self-enrollment and adjust self-enrollment settings, go to Authentication > Self-service Portal > Device Self-enrollment and select Enable userdevice certificate self-enrollment.

SCEP enrollment template	Select a SCEP enrollment template from the drop-down list. SCEP can be configured in Certificate Management > SCEP. See SCEP on page 147 for more information.
Max. devices	Set the maximum number of devices that a user can self-enroll.
Key size	Select the key size for self-enrolled certificates (1024, 2048, or 4096 bits). iOS devices only support two key size: 1024 and 2048.
Enable self-enrollment for Smart Card certificate	Select to enable self-enrollment for smart card certificates. This requires that a DNS domain name be configured, as it is used in the CRL Distribution Points (CDPs) certificate extension.

Port-based Network Access Control Non-compliant devices

Select OK to apply any changes you have made.

Non-compliant devices

802.1X methods require interactive entry of user credentials to prove a user’s identity before allowing them access to the network. This is not possible for non-interactive devices, such as printers. MAC Authentication Bypass is supported to allow non-802.1X compliant devices to be identified and accepted onto the network using their MAC address as authentication.

This feature is only for 802.1X MAC Authentication Bypass. FortiGate Captive Portal MAC Authentication is supported by configuring the MAC address as a standard user, with the MAC address as both the username and password, and not by entering it in the MAC Devices section.

Multiple MAC devices can be imported in bulk from a CSV file. The first column of the CSV file contains the device names (maximum of 50 characters), and the second column contains the corresponding MAC addresses (0123456789AB or 01:23:45:67:89:AB).

To configure MAC-based authentication for a device:

Go to Authentication > User Management > MAC Devices. The MAC device list will be shown.
If you are adding a new device, select Create New to open the Create New MAC-based Authentication Device

If you are editing an already existing device, select the device from the device list.

Enter the device name in the Name field, and enter the device’s MAC address in the MAC address
Select OK to apply your changes.

To import MAC devices:

In the MAC device list, select Import.
Select Browse to locate the CSV file on your computer.
Select OK to import the list.

The import will fail if the maximum number of MAC devices has already been reached, or if any of the information contained within the file does not conform, for example if the device name too long, or there is an incorrectly formatted MAC address.

Configuring Policies

Configuring policies

The Policy menu lets you create policies that use profiles to filter email.

It also lets you control who can send email through the FortiMail unit, and stipulate rules for how it will deliver email that it proxies or relays.

• What is a policy?

How to use policies
Controlling SMTP access and delivery
Controlling email based on recipient addresses
Controlling email based on IP addresses

What is a policy?

A policy defines which way traffic will be filtered. It may also define user account settings, such as authentication type, disk quota, and access to webmail.

After creating the antispam, antivirus, content, authentication, TLS, or resource profiles (see “Configuring profiles” on page 482), you need to apply them to policies for them to take effect.

FortiMail units support three types of policies:

Access control and delivery rules that are typical to SMTP relays and servers (see

“Controlling SMTP access and delivery” on page 456)

Recipient-based policies (see “Controlling email based on recipient addresses” on page 468)
IP-based policies (see “Controlling email based on IP addresses” on page 475)

Recipient-based policies versus IP-based policies

Recipient-based policies

The FortiMail unit applies these based on the recipient’s email address or the recipient’s user group. May also define authenticated webmail or POP3 access by that email user to their per-recipient quarantine. Since version 4.0, the recipient-based policies also check sender patterns.

IP-based policies

The FortiMail unit applies these based on the SMTP client’s IP address (server mode or gateway mode), or the IP addresses of both the SMTP client and SMTP server (transparent mode).

Page 453

Incoming versus outgoing email messages

There are two types of recipient-based policies: incoming and outgoing. The FortiMail unit applies incoming policies to the incoming mail messages and outgoing policies to the outgoing mail messages.

Whether the email is incoming or outgoing is decided by the domain name in the recipient’s email address. If the domain is a protected domain, the FortiMail unit considers the message to be incoming and applies the first matching incoming recipient-based policy. If the recipient domain is not a protected domain, the message is considered to be outgoing, and applies outgoing recipient-based policy.

To be more specific, the FortiMail unit actually matches the recipient domain’s IP address with the IP list of the protected SMTP servers where the protected domains reside. If there is an IP match, the domain is deemed protected and the email destined to this domain is considered to be incoming. If there is no IP match, the domain is deemed unprotected and the email destined to this domain is considered to be outgoing.

For more information on protected domains, see “Configuring protected domains” on page 380.

If the FortiMail unit uses the same FQDN as your mail server, it may become difficult to distinguish the two devices during troubleshooting. Note: You should use a different host name for each FortiMail unit, especially when you are managing multiple FortiMail units of the same model, or when configuring a high availability (HA) cluster. This will let you to distinguish between different members of the cluster. If the FortiMail unit is in HA mode, the FortiMail unit will add the host name to the subject line of alert email messages. For details, see “Configuring alert email” on page 682.
Local domain name	Enter the local domain name to which the FortiMail unit belongs. The local domain name is used in many features such as email quarantine, Bayesian database training, quarantine report, and delivery status notification (DSN) email messages. Displays the FortiMail unit’s fully qualified domain name (FQDN) is in the format: <host-name>.<local-domain-name> such as fortimail-400.example.com, where fortimail-400 is the Host name and example.com is the Local domain name. Note: The IP address should be globally resolvable into the FQDN of the FortiMail unit if it will relay outgoing email. If it is not globally resolvable, reverse DNS lookups of the FortiMail unit’s domain name by external SMTP servers will fail. For quarantine reports, if the FortiMail unit is operating in server mode or gateway mode, DNS records for the local domain name may need to be globally resolvable to the IP address of the FortiMail unit. If it is not globally resolvable, web and email release/delete for the per-recipient quarantines may fail. For more information on configuring required DNS records, see “Setting up the system” on page 25. Note: The Local domain name is not required to be different from or identical to any protected domain. It can be a subdomain or different, external domain. For example, a FortiMail unit whose FQDN is fortimail.example.com could be configured with the protected domains example.com and accounting.example.net.
SMTP server port number	Enter the port number on which the FortiMail unit’s SMTP server will listen for SMTP connections. The default port number is 25.
GUI item	Description
SMTP over SSL/TLS	Enable to allow SSL- and TLS-secured connections from SMTP clients that request SSL/TLS. When disabled, SMTP connections with the FortiMail unit’s built-in MTA must occur as clear text, unencrypted. Note: This option must be enabled to receive SMTPS connections. However, it does not require them. To enforce client use of SMTPS, see “Configuring access control rules” on page 456.
SMTPS server port number	Enter the port number on which the FortiMail unit’s built-in MTA listens for secure SMTP connections. The default port number is 465. This option is unavailable if SMTP over SSL/TLS is disabled.
SMTP MSA service	Enable let your email clients use SMTP for message submission on a separate TCP port number from deliveries or mail relay by MTAs. For details on message submission by email clients as distinct from SMTP used by MTAs, see RFC 2476 .
SMTP MSA port number	Enter the TCP port number on which the FortiMail unit listens for email clients to submit email for delivery. The default port number is 587.
POP3 server port number	Enter the port number on which the FortiMail unit’s POP3 server will listen for POP3 connections. The default port number is 110. This option is available only if the FortiMail unit is operating in server mode.
Default domain for authentication	If you set one domain as the default domain, users on the default domain only need to enter their user names without the domain part for webmail/SMTP/IMAP/POP3 authentication, such as user1. Users on the non-default domains must enter both the user name part and domain part to authentication, such as user2@example.com.

Webmail access Enable to redirect HTTP webmail access to HTTPS.

Configuring DSN options

Use this section to configure mail server delivery status notifications.

For information on failed deliveries, see “Managing the deferred mail queue” on page 179 and “Managing undeliverable mail” on page 181.

For more information on DSN, see “Managing the deferred mail queue” on page 179.

GUI item	Description
DSN (NDR) email generation	Enable to allow the FortiMail unit to send DSN messages to notify email users of delivery delays and/or failure.
GUI item	Description
Sender displayname	Displays the name of the sender, such as FortiMail administrator, as it should appear in DSN email. If this field is empty, the FortiMail unit uses the default name of postmaster.

Sender address Displays the sender email address in DSN.

If this field is empty, the FortiMail unit uses the default sender email address of postmaster@<domain_str>, where <domain_str> is the domain name of the FortiMail unit, such as example.com.
