ThoughtSpot integrates with SAML for authentication.

SAML SSO authentication

ThoughtSpot supports the Single Sign-On (SSO) authentication method with the Security Assertion Markup Language (SAML) authentication and authorization framework. With SAML SSO, users can authenticate to the SAML identity provider (IdP) at your federation to access the ThoughtSpot application, or the embedded ThoughtSpot content in an external web application. It also allows them to navigate seamlessly between different application interfaces with their existing credentials.

By default, local authentication is enabled. Use this article to learn how to configure a SAML integration with an external IdP. To configure SAML in an embedded environment, refer to SAML SSO authentication.

SAML authentication with multiple IDPs

You may have multiple groups of users who need to log into ThoughtSpot but are managed by separate IDPs. You can configure SAML SSO login for more than one Identity Provider. To configure this, contact ThoughtSpot Support.

About SAML authentication

The SAML SSO authentication involves several entities and components.

SAML entities

SAML is an XML standard that allows secure exchange of user authentication and authorization data between trusted partners. It enables the following entities to exchange identity, authentication, and authorization information:

  • Identity Provider (IdP)

    The Identity Management system that maintains the user identity information. IdP acts as a SAML authority and authenticates SSO users. ThoughtSpot supports SAML authentication framework with popular Identity Providers such as Okta, Azure Active Directory, PingFederate, Microsoft AD FS, and Onelogin. This is not an exhaustive list. To determine if ThoughtSpot supports your preferred IdP, talk to your ThoughtSpot contact.

    After you complete the SAML configuration in ThoughtSpot that this article describes, refer to your Identity Provider’s SAML documentation for specific information on setting up SAML with that IdP.

  • Service Provider (SP)

    The provider of a business function or application service; for example ThoughtSpot. The SP relies on the IdP to authenticate users before allowing access to its services.

  • Federated user

    A user whose identity information is managed by the IdP. The federated users have SSO credentials and authenticate to IdP to access various application services.

SAML assertion and attributes

Both SP-initiated and IdP-initiated authentication workflows rely upon assertions that are exchanged between the SAML endpoints through a web browser.

Some of the most commonly used elements are:

  • SAML assertion

    The user authentication and authorization information issued by the IdP. SAML assertions contain all the information necessary for a service provider to confirm if the user identity is valid.

    ThoughtSpot supports 2 methods to increase the duration of validity for your SAML assertion: the SessionNotOnOrAfter attribute and the maxAuthenticationAge parameter. You can ask ThoughtSpot to disable either one of these checks. If you use both, and either check fails, ThoughtSpot does not authenticate the user. Some IDPs do not support use of SessionNotOnOrAfter. If your IDP does not support use of SessionNotOnOrAfter, remove that attribute from your IDP assertion and ask ThoughtSpot Support to enable maxAuthenticationAge.

  • Metadata

    Data in the XML format to establish interoperability between the IdP and SP. It contains the URLs of the endpoints, entity ID, and so on.

  • Assertion Services Consumer (ACS) URL

    The endpoint URL to which the user’s browser sends the SAML response received from the IdP after authenticating a user.

  • Entity ID

    A unique service name to identify the client application from which the SSO login request originates.

  • SAML attributes

    The attributes associated with the user; for example, username and email address.

Enable SAML authentication

You need admin privileges to enable SAML SSO authentication.

  1. Configure the ThoughtSpot application instance on your IDP server.

  2. Log into your ThoughtSpot application instance.

  3. From the top navigation bar, select the Admin tab.

  4. Select SAML from the side navigation bar that appears.

  5. Click the Configure button in the middle of the screen.

  6. Fill in the following parameters:

    Configure SAML

    ThoughtSpot Service Address
    A fully qualified and resolvable domain name for the ThoughtSpot service. This must be in the format <cluster-name>.thoughtspot.com.
    Port
    Enter 443 in this box. This is the port of the server where your ThoughtSpot instance is running.
    Unique Service Name
    The unique key used by your Identity Provider to identify the client. For example, urn:thoughtspot:callosum:saml. You may know this as the Entity ID.
    Skew Time in Seconds
    The allowed skew time, after which the authentication response is rejected and sent back from the IDP. 86400 is a popular choice. The default is 3600.
    Protocol
    The connection protocol for ThoughtSpot. Use https.
    IDP Metadata XML File

    The absolute path to your Identity Provider’s metadata file. This file is provided by your IDP. You need this file so that the configuration persists over upgrades. It is a best practice to set it up on persistent/HA storage (NAS volumes) or in the same absolute path on all nodes in the cluster. For example, idp-meta.xml. If your IDP needs an Assertion Consumer Service URL to create the metadata file, use https://<hostname_or_IP>:443/callosum/v1/saml/SSO. Note that this URL is case-sensitive.

    If your IdP does not allow you to import the IdP metadata XML file, you must map values between ThoughtSpot and your IDP manually. This allows the ThoughtSpot system to automatically pick up certain attributes and subjects, such as a user's email address, display name, and username. Map the username attribute value in your IDP (userPrincipalName in Okta, for example) to NameId, map the email attribute value to mail, and map the display name subject value to displayName. Attributes and subjects appear in separate sections of your SAML assertion. It is mandatory to fill out the mail field. If your company cannot meet this requirement, contact ThoughtSpot Support.

    For additional support with the attribute statements, refer to your IDP's SAML documentation. ThoughtSpot supports SAML authentication framework with popular Identity Providers such as Okta, Azure Active Directory, PingFederate, Microsoft AD FS, and Onelogin. This is not an exhaustive list. To determine if ThoughtSpot supports your preferred IdP, talk to your ThoughtSpot contact.
    Automatically add SAML users to ThoughtSpot upon first authentication
    Choose whether or not to add SAML users to ThoughtSpot when they first authenticate. If you choose 'yes', then new users will be automatically created in ThoughtSpot upon first successful SSO login. If you choose 'no', then SAML users will not be added in ThoughtSpot upon first successful SSO login. Instead, you must add users manually.

  7. After you fill in all parameters, click OK.

  8. When the configuration is complete, download ThoughtSpot’s metadata file, spring_saml_metadata.xml. This file contains the public key you need if you want to encrypt your SAML assertions. To download this file, navigate to https://<hostname-or-IP>/callosum/v1/saml/metadata/. The file automatically downloads.

Configure the IdP

To enable the IdP to recognize your host application and ThoughtSpot as a valid service provider, you must configure the IdP with required attributes and metadata.

ThoughtSpot supports SAML authentication with several identity and access management providers, such as Okta, Azure Active Directory, PingFederate, Microsoft AD FS, Onelogin and so on. If you want to use one of these providers as your IdP, make sure you read the SAML configuration steps described in the Identity provider’s documentation site.

To determine if ThoughtSpot supports your preferred IdP, contact ThoughtSpot support.

Complete your configuration of the IdP using the IdP’s SAML documentation. Upload or copy the contents of the spring_saml_metadata.xml to your IdP server. This file contains the public key you need if you want to encrypt your SAML assertions. If you did not download the spring_saml_metadata.xml file, navigate to https://<your_ThoughtSpot_hostname-or-IP>/callosum/v1/saml/metadata/. The file automatically downloads.

SAML group mapping

You can map your SAML groups from your IDP to your ThoughtSpot groups. This means that you do not have to manually recreate your groups in ThoughtSpot, if they are already present in your IDP. Refer to Configure SAML group mapping.
