Identity provider

As explained in Architecting an Apache Iceberg Lakehouse

An identity provider is a system that authenticates users or services and supplies their identities and authorization context to other systems.

An identity provider (IdP) authenticates users or services and supplies identities and authorization context to applications, catalogs, and storage systems. Centralizing authentication decouples security policy from individual applications, reducing password sprawl while enabling consistent monitoring and access enforcement. section 5.4.9 section 7.2.2

Identity providers support architecture across hybrid and multicloud environments by:

  • Integrating cloud applications, third-party services, and enterprise systems through SSO, multifactor authentication, and conditional access. section 5.4.9
  • Bridging LDAP directories and cloud identity systems so legacy applications and modern SaaS platforms share governed access. section 5.4.9
  • Supplying identities to catalogs, which can apply RBAC, ABAC, and scoped credentials to tables and namespaces. section 7.2.2

Lakehouse access control

An enterprise can connect a catalog to OAuth, LDAP, SAML, or enterprise SSO, then restrict table access by role or attributes such as department. Storage platforms may likewise integrate with an IdP for fine-grained enforcement. section 5.5.2 section 7.2.2

How Architecting an Apache Iceberg Lakehouse covers it

How deep it goes
Explains federation, policy integration, and authorization patterns, but stops short of protocol or provider implementation detail.
Examples
Names Azure Active Directory, Okta, Auth0, Google Identity, Active Directory, OpenLDAP, and 389 Directory Server.
What you can do after
Operate/configure centralized access policies across storage and catalogs using federated identities and role or attribute controls.
How it connects
Connects LDAP, single sign-on, multifactor authentication, OAuth, SAML, OpenID Connect, RBAC, ABAC, catalogs, and lineage.
