Setting up Active Directory Roles sync with SAML SSO

Active Directory (AD) synchronization ensures that user identities and permissions are consistent and secure across on-premises and Snorkel Flow environments.

Prerequisites​

  • Working single sign-on (SSO) install. See Configure SAML SSO. If SSO is configured to be required, no user should be able to log in via username/password and bypass the AD roles sync.
  • Use Active Directory as an identity provider (IdP).
  • Have ability to configure additional role information and provide these roles via SAML attributes.
  • Snorkel Flow platform installed via Helm on Kubernetes.

Set up AD roles in identity provider​

Set up the identity provider (IdP) so that when a certain scope is requested, the userinfo response returns a claim that lists the AD roles or a comma-separated set of AD roles.

  1. In Admin settings, select Authentication Settings.
  2. Optional: Enter a specific admissions role.
  3. Enter the scope and claim for your role.
  4. Assign the specific permissions to the defined roles. Users have access to the resources based on their assigned roles.
    AD roles from the claim are a comma-separated string containing all roles or a list of strings. The list of AD roles should be formatted as<PREFIX><SEPARATOR><WORKSPACE><SEPARATOR><SF-ROLE> or <WORKSPACE><SEPARATOR><SF-ROLE>:
  • PREFIX: Set in Helm template. If not defined, can be left empty.
  • SEPARATOR: Character(s) to separate components of AD role. For example, _ or -.
  • WORKSPACE: Specific workspace to which role applies. For superadmin roles, define as ALL_WORKSPACE. You cannot set a role in the default workspace.
  • SF-ROLE: The Snorkel Flow role, such as ANNOTATOR.

Enabling AD Roles sync​

To enable AD Roles sync for SAML, enable authorization.adRoles like the following:

authorization:
  adRoles:
    enabled: 1
    saml:
      attributeName: csgroups
    prefix: DTCA_CFG_DTI_EA_AIDLP
    separator: _$
  • authorization.adRoles.enabled: Enables the feature. Notice that this is 1 and not true.
  • authorization.adRoles.saml.attributeName: Specifies which custom attribute to look for the roles in the SAML response.
  • authorization.adRoles.prefix: Specifies the expected prefix of the role.
  • authorization.adRoles.separator: Specifies the expected separator between the prefix, workspace, and user role.

All of these parameters except authorization.adRoles.prefix must be set if AD roles sync is enabled.
