SAML Integration (Enterprise Edition)

Determined EE provides a SAML integration to allow users to use single sign-on (SSO) with their organization’s identity provider (IdP) and to provide system administrators better control over access to resources. Currently, the only officially supported identity provider is Okta.

Configuring your IdP

When configuring your IdP to allow users to SSO to Determined, you will need to specify the location of Determined’s SSO URL and the audience URL. The audience URL should be set to the Determined master’s base URL and the SSO endpoint is at that base URL with a path of /saml/sso.

Determined also requires an additional attribute named userName with name format unspecified set to the username of the user attempting SSO (e.g., for Okta, this is the attribute value user.login).

Configuring Determined

Determined requires your IdP’s SSO URL, descriptor SSO URL, public certificate, and name as well as the hostname your IdP intends to use to communicate with Determined. These are all supplied in the master.yaml.

Example Setup with Okta

In this example, we assume the Determined master will run at https://determined.example.com.

First, in Okta, you’ll need to create a new SAML application and specify the following options:

Field

Example Value

Single sign on URL

https://determined.example.com/saml/sso

Audience URI (SP Entity ID)

https://determined.example.com

Name ID format

Unspecified

Application username

Okta username

Determined also requires an attribute statement named userName with the name format unspecified and a value user.login.

Okta will show that more steps are required to complete the configuration and link to a page with their IdP SSO URL, IdP Issuer URL (synonymous to IdP Descriptor URL), and public certificate. Use these to configure the Determined master in master.yaml. The cert will need to be saved and mounted into the master’s container.

saml:
  enabled: true
  provider: "Okta"
  idp_recipient_url: "https://determined.example.com/saml/sso"
  idp_sso_url: "https://myorg.okta.com/app/.../sso/saml"
  idp_sso_descriptor_url: "http://www.okta.com/..."
  idp_cert_path: "okta.cert"

Once the master is started with this configuration, users should be able to login to Determined from Okta by clicking the Determined tile after they have been provisioned.
