Every new security platform faces the same architectural question on day one: where do its users come from? A PAM deployment that answers "from its own local user store" has, in the act of centralising privileged access, created one more island of identities - one more password to manage, one more MFA enrolment to run, one more place where a leaver's account can linger. The platform guarding the most sensitive access in the enterprise should not be the place where identity discipline starts over from scratch.
The enterprise challenge: the control plane's own identities
The identities that access a PAM platform are, by definition, the most consequential in the estate - administrators, operators, vendors. Managing them locally reproduces every familiar failure at the worst possible location: onboarding lag means engineers share PAM logins "temporarily"; offboarding lag means a departed administrator's portal account survives; a separate password and factor set means the organisation's carefully built authentication policy - conditional rules, phishing-resistant factors, lockout behaviour - simply does not apply at the door to production. And the audit picture splits: the identity team attests one authentication regime, while privileged access quietly runs another.
Why federation is the structural answer
Federation resolves the question by refusing to duplicate: the PAM platform delegates authentication to the identity provider the enterprise already operates, over a standard protocol. Authentication policy, factor enforcement and account lifecycle remain where they already live and are already governed - and privileged access inherits all of it automatically. One identity, one authentication posture, one leaver-disablement that ends everything at once.
The Tanflow approach: SAML 2.0 federation as a built-in
Tanflow PAM federates with SAML 2.0 identity providers as a native capability - Tanflow names the Tanflow IAM Suite itself, Azure AD / Entra ID, Okta, Keycloak, ADFS and Google Workspace, alongside any SAML 2.0-compliant IdP. In Tanflow's own framing, privileged access inherits your existing authentication and MFA posture: the administrator reaching for a production shell authenticates exactly the way your identity architecture says administrators authenticate.
Federation composes cleanly with the platform's own controls rather than replacing them. The gateway's own MFA options - TOTP, OTP, FIDO2 - remain available where policy wants an additional factor at the privileged boundary specifically. Inside the platform, Tanflow PAM's roles and access control still govern which targets, accounts and protocols each federated identity may use; the IdP answers who you are, PAM answers what you may touch. And every session retains the full chain regardless of authentication origin: vault injection, recording, command control, audit.
For organisations running the Tanflow IAM Suite, the pairing closes the loop entirely: the suite's Identity Directory and lifecycle automation govern the identity; SAML federation carries it into PAM; and a leaver processed once in the directory loses application access and privileged access in the same instant.
The federated login flow
- An engineer browses to the PAM portal, which redirects to the corporate IdP.
- The IdP authenticates them under enterprise policy - password, factors, conditions - and returns a signed SAML assertion.
- Tanflow PAM maps the asserted identity to its roles and shows the targets that identity is authorised for.
- Sessions proceed under the standard chain - injection, recording, command policy - attributed to the federated identity throughout.
Enterprise scenario
Consider an enterprise standardised on Entra ID with FIDO2 keys enforced for its infrastructure team. Federating Tanflow PAM means that posture extends to production access on the day federation is configured - no re-enrolment, no parallel factor rollout. When an infrastructure engineer resigns, the standard leaver process disables one Entra ID account; the PAM portal, and every target behind it, stops accepting that identity in the same action. The access review that used to reconcile two user lists now reads one.
Security and audit implications
Federation makes the enterprise's authentication attestation whole: one policy, demonstrably applied everywhere including the privileged boundary. It removes the orphaned-PAM-account failure mode at its root, and it simplifies the evidence - the IdP's authentication log and PAM's session record join into a single, coherent story per access. Tanflow's comparison table lists SAML 2.0 SSO federation as built-in, against DIY integration work in open-source assemblies.
Conclusion
A privileged access platform should strengthen the identity architecture, not fork it. By federating with the enterprise's existing SAML 2.0 identity provider - or with the Tanflow IAM Suite as the natural pairing - Tanflow PAM lets privileged access inherit the authentication posture the organisation has already built, and reserves its own machinery for what happens after the login: the targets, the sessions, the commands and the record.
