Seldon Deploy integrates with Single Sign-On (SSO) providers for authentication.
The SSO system may also host the identities, or it may integrate to an IdP. The IdP is often a source of truth for users across the organisation.

In order for group-based filtering to be used, groups need to be available. These come from an IdP but not all IdPs support groups or support groups in integration to SSO.

If groups are to be used, we suggest integrating either keycloak or dex to LDAP. See, for example:
Or search the official documentation of those products for the latest details.
