Hi,
DSS can authenticate users using any SAML v2 Identity Provider (like Azure AD, Okta, PingFederation, Google, ...).
When a user tries to login to DSS, he will be redirect to the centralized login page, where he can login (if not already done) and he will then be redirected to DSS with the proper identity
We do not have specific videos on this (it's really not a very visual feature), but we do have more documentation on that https://doc.dataiku.com/dss/latest/security/sso.html
