Engineering focus

A shared identity layer. Rules for each application.

AD API Center brings repeated domain-authentication work into a central gateway. Application profiles keep access rules specific to each system, while a common interface connects internal applications, tools, and scripts to the same identity foundation.

01 / Context

Repeated authentication work becomes integration overhead.

Internal applications often need the same domain identity foundation while enforcing different access rules. Implementing that foundation separately in every application creates repeated work across tools, services, and scripts.

02 / The system

One gateway, with a profile for every application.

AD API Center separates common domain integration from application-specific access decisions. Each application receives a profile and an endpoint for checking the current domain user’s access. An administration interface manages rules, and origin binding ties each profile to the application that owns it. Active Directory lookups and authentication behavior sit behind the shared gateway.

03 / Capabilities

Central identity integration with application-specific rules.

Application-specific policy

Profiles define access rules for individual applications, tools, and scripts.

Origin-bound profiles

Each application profile is tied to the origin that owns it, making that relationship part of the access model.

Central domain integration

Active Directory lookups and authentication behavior are brought behind a shared gateway for internal HTTP and HTTPS systems.

04 / System map

An application request meets its access policy.

This conceptual sequence explains how the project’s main capabilities connect.

  1. Define the application

    An application profile captures the system’s access rules.

  2. Connect the request

    The internal application calls its assigned access endpoint.

  3. Check domain identity

    The gateway handles the user’s domain identity and applicable rules.

  4. Return the decision

    The application receives the result for its own access workflow.

05 / Scope & status

Current project scope.

Built for internal HTTP and HTTPS applications, tools, and scripts.
