Who Can See This File? Bringing SSO-Grade Access Control to Enterprise Documents

This post explains the "permission gap" between centralized identity/SSO systems and how documents are shared or stored, describing risks such as stale shared links, detached audit trails, and compliance failures; it recommends applying SSO principles to files by tying document permissions to the IdP and implementing role-based permissions, field-level visibility, expiring access, and integrated audit logs so deprovisioning and role changes automatically propagate to document access.
