SAML admin authentication

SAML can be enabled across devices, enabling smooth movement between devices for the administrator. FortiManager can play the role of the identity provider (IdP) or the service provider (SP) when an external identity provider is available.

Devices configured to the IdP can be accessed through the Quick Access menu which appears in the top-right corner of the main menu. The current device is indicated with an asterisk (currently only supported between FAZ/FMG).

Logging into an SP device will redirect you to the IdP login page. By default, it is a Fortinet login page. After successful authentication, you can access other SP devices from within the same browser without additional authentication.

When FortiManager is registered to FortiCloud, you can enable Allow admins to login with FortiCloud. This feature allows administrators to log in to FortiManager using their FortiCloud SSO account credentials. See FortiCloud SSO admin authentication .

The admin user must be created on both the IdP and SP, otherwise you will see an error message stating that the admin doesn't exist. Alternatively, you can configure the ADOM and profile names in the SP to match the IdP. When this is done, you can create one SAML SSO wildcard admin user on the SP to match all users on the IdP server.

When accessing FortiGate from the Quick Access menu, if FGT is set up to use the default login page with SSO options, you must select the via Single Sign-On button to be automatically authenticated.

To configure FortiManager as the identity provider:

1. Go to System Settings > Admin > SAML SSO.
2. Select Identity Provider (IdP).
3. In the IdP Certificate dropdown, choose a certificate where IdP is used.
4. Select Download to get the IdP certificate, used later to configure SPs.
5. (Optional) A custom login page can be created by moving the Login Page Template toggle to the On position and selecting Customize.
6. In the SP Settings table, select Create New to add a service provider.
7. In the Edit Service Provider window, configure the following information:

   Name	Enter a name for the service provider.
   IdP Prefix	Copy the IdP prefix. This will be required when configuring your service providers.
   SP Type	Select Fortinet as the SP Type. If the SP is not a Fortinet product, select Custom as the SP Type and copy the SP Entity ID, SP ACS (Login) URL, and SP SLS (Logout) URL from your SPs configuration page.
   SP Address	Enter the IP address of the service provider.
   SAML Attributes	SAML attributes can be added to a service provider to specify ADOM and/or profile names. FortiManager acting as IdP supports the following SAML attributes: Type: Username, Attribute: username Type: Profile Name, Attribute: profilename Type: ADOM, Attribute: adoms SAML SSO Wildcard users As long as the SP has the same user profile and ADOM names as the IdP, you do not need to re-create each user from the IdP on the SP. Instead, you can create one SAML SSO wildcard admin user on the SP with the Match all users on remote server setting enabled to match all users on the IdP server. When logging in as an SSO user on the SP, the user is assigned the same profile and ADOMs as are configured on the IdP. See Creating administrators.

8. Select OK to save changes to the service provider.
9. Click Apply to save the IdP configuration.

To configure FortiManager as a service provider:

Go to System Settings > SAML SSO.

Select Service Provider (SP).

Enter the Server Address which is the browser accessible address for this device.

Optionally, configure the signing options:

• Authentication Request Signed: Enable this setting to require that all authentication requests sent by the FortiManager service provider are signed. A valid SP certificate is required to enable this option.
• Require Assertions Signed from IdP: Enable this setting to require that all assertions received from the IdP are signed.

Configure the IdP Settings:

1. Select the IdP type as Fortinet or Custom.
2. Enter the IdP Address and the Prefix that you obtained while configuring the IdP device.
3. Select the IdP certificate. If this is a first-time set up, you can import the IdP certificate that you downloaded while configuring the IdP device.

Confirm that the information is correct and select Apply.

Repeat the steps for each FAZ/FMG that is to be set as a service provider.

Supported SAML attribute overrides

The following SAML attributes are accepted by FortiManager SAML service provider.

SAML Attribute	Description
username	The username of the local/SSO user. This attribute is mandatory. Example: <Attribute Name="username"> <AttributeValue>user1</AttributeValue> </Attribute>
profilename	The Profile assigned to the user. If a matching profile exists on the FortiManager, it will be assigned to the user. This attribute is optional. Example: <Attribute Name="profilename"> <AttributeValue>SSOPROFILE</AttributeValue> </Attribute>
adoms	The ADOM(s) to which the user will have access. Multiple ADOMs can be specified in the SAML assertion if supported by the IdP. This attribute is optional. Example: <Attribute Name="adoms"> <AttributeValue>ADOM1</AttributeValue> <AttributeValue>ADOM2</AttributeValue> </Attribute>

You can use the following command in the CLI to verify the correct adoption of the SAML attributes by FortiManager.
