Set Up SAML Authentication
Security Assertion Markup Language (SAML) is an XML-based, open-standard data format used to exchange authentication and authorization data between parties, specifically between an identity provider (IdP) and a service provider. SAML is a product of the OASIS Security Services Technical Committee.
- Create a server profile.The server profile identifies the external authentication service and instructs the firewall on how to connect to that authentication service and access the authentication credentials for your users.The following steps describe how you can import a SAML metadata file from the IdP so that the firewall can automatically create a server profile and populate the connection, registration, and IdP certificate information. If the IdP does not provide a metadata file, select, and thenDeviceServer ProfilesSAML Identity ProviderAdda server profile manually.
- Export the SAML metadata file from the IdP to an endpoint that the firewall can access.Refer to your IdP documentation for instructions on how to export the file.
- Select.DeviceServer ProfilesSAML Identity Provider
- Importthe metadata file onto the firewall.
- Enter aProfile Nameto identify the server profile, such asGP-User-Auth.
- Browsefor the metadata file.
- (Recommended) SelectValidate Identity Provider Certificate(default) so that the firewall validates the IdP certificate.Validation occurs only after you assign the server profile to an authentication profile andCommitthe changes. The firewall uses the certificate profile within the authentication profile to validate the certificate.
- Enter theMaximum Clock Skew, which is the allowed system time difference (in seconds) between the IdP and the firewall when the firewall validates IdP messages. The default value is 60 seconds, and the range is 1 to 900 seconds.If the difference exceeds this value, authentication fails.
- ClickOKto save the server profile.
- (Optional) Create an authentication profile.The authentication profile specifies the server profile that the portal or gateways use when they authenticate users. On a portal or gateway, you can assign one or more authentication profiles to one or more client authentication profiles. For more information on how an authentication profile within a client authentication profile supports granular user authentication, see Configure a GlobalProtect Gateway and Set Up Access to the GlobalProtect Portal.
- Select, and thenDeviceAuthentication ProfileAdda new authentication profile.
- Enter aNamefor the authentication profile.
- Set theAuthenticationTypetoSAML.
- Select the SAMLIdP Server Profilethat you created in step 1.
- Configure the following options to enable certificate authentication between the firewall and the SAML identity provider. Refer to SAML 2.0 Authentication for more details.
- TheCertificate for Signing Requeststhat the firewall uses to sign messages that it sends to the IdP.
- TheCertificate Profilethat the firewall uses to validate the IdP certificate.
- Specify the username and admin role formats.
Unlike other external authentication types, the SAML authentication profile does not have aUser Domainattribute.
- Specify theUsername AttributeandUser Group Attribute.
- (Optional) If you plan to use this profile to authenticate the administrative accounts that you manage in the IdP identity store, specify theAdmin Role AttributeandAccess Domain Attribute.
- On theAdvancedtab,AddanAllow Listto select the users and groups that are allowed to authenticate with this profile. Thealloption allows every user to authenticate with this profile. By default, the list has no entries, which means no users can authenticate.Make sure the username in theAllow Listmatches the username returned from the SAML IdP server.
- Committhe configuration.
- (For Chromebooks only) Install theLaunch the ChromeWeb Storeand install theSAML SSO for Chrome Appsextension.
- (For Chromebooks only) Configure SAML Single Sign-On for Chrome apps.In order for GlobalProtect to support SAML SSO, the GlobalProtect application ID (nicidmbokaedpmoegdbcebhnchpegcdc) must be added to the allow list configuration file for theSAML SSO for Chrome Appsextension.
