Description of federated authentication and authorization for Municipal Users using SEB and KOMBIT ConcextHandler.

 

Authorization Flow

When a client starts an OIDC Authorization Code Flow for a municipal user, it uses SEB and KOMBIT Context Handler and goes through the following federation process.

Federation of Authentication and Authorization for Municipal Users (return of OIDC Tokens and use of eHealth Infrastructure omitted)

The sequence diagram for clinicians' logins, explained in Client Application Login and Logout to eHealth Infrastructure | Clinical logins, shows how the OIDC Authorization Code Flow is redirected through a series of steps involving OIOSAML-based AuthNRequest and AuthNResponse.

Here's a summary of the responsibilities of the services involved:

  1. The KOMBIT Context Handler created a SAML AuthnResponse based on registrations stored in the KOMBIT user administration system KOMBIT STS Administration (STS Admin or DK Admin for short).

  2. The eHealth Infrastructure-hosted SAML Proxy - This service does tasks like substituting and translating KOMBIT-flavor SAML Attributes to ensure uniform OIOSAML OIO-BPP Attributes are provided to SEB. It also enhances OIOSAML Attributes by adding the employee's CPR number, obtained from the KOMBIT FK Organisation system.

  3. Sundhedsvæsenets Elektroniske Brugerstyring (SEB) - This is the shared user administration platform for the Danish healthcare sector.

  4. The eHealth Authorization Service (KeyCloak) - When the KOMBIT NSIS Context Handler can connect directly with SEB, the SAML-proxy is removed from the flow. The KeyCloak service shall then modify and adapt KOMBIT-style SAML Attributes to ensure they match the uniform OIOSAML OIO-BPP Attributes used.

KOMBIT Terms and Concepts

The English terms used in the following do not constitute official, KOMBIT translations of the Danish terms used throughout KOMBIT documentation and systems. The Danish terms stem from section 3 in Brugervejledning til Administrationsmodulerne for leverandører.

The following terms are used in registrations in “Fælleskommunalt Administrationsmodul” (KOMBIT STS Admin):

Term

Description

User system

(Danish: Brugervendt system)

An IT system that provides an access-controlled user interface,
accessed via a browser. That is, a system directly used by an end-user.

A user system registered in the KOMBIT STS admin enables it to use KOMBIT systems for access control of end-users.

User system role

(Danish: Brugersystemrolle)

Grouping of rights or permissions that define access and access restrictions to a specific user-facing system

Data constraint

(Danish: Dataafgrænsning)

Restriction of a “user system role”, which narrows the system role's field of action

Job function role

(Danish: Jobfunktionsrolle)

Grouping of user system roles for an authority (e.g. municipality) used by the authority to assign access to the user.

Each municipality shall maintain a set in KOMBIT STS Admin.

Concerning eHealth Infrastructure, the job function role should comprise:

  • A collection of user system roles

  • An Organisation identifier

  • A possible CareTeam identifier

Registrations Required in Municipal KOMBIT Systems

eHealth Infrastructure as User-systems

The eHealth test environments use KOMBIT Context Handler for access control and therefore are registered as user-facing systems in the FK Administration system

The following eHealth environments are registered as user-facing systems in the KOMBIT external test:

“T-SEB”

They are being used in the future when SEB and ContextHandler are directly connected. The name is not known by Systematic.

T-SEB for all eHealth test (incl. pre-prod) environments.

FUT-S has created similar registrations in the KOMBIT FK Admininistratino in the KOMBIT production environment. This only has the SAML Proxy for the eHealth Infrastructure production environment (PROD).

Data constraints (Danish: “data afgrænsninger”)

The data constraints narrow the user system role. In eHealth Infrastructure, there are two data constraints in use:

  • CareTeam - a system-specific data constraint identifying a CareTeam. The optional for some user system roles, required for others (see below)

  • Organisation—This is a cross-cutting (data constraint) identifying Organisation from KOMBIT FK Organisation. This data constraint is defined and maintained outside eHealth.

The following screenshot shows the “Fælleskommunalt Administrationsmodul” user interface for creating data constraints and mandatory fields.

Getting municipal employee CPR

To allow regional and municipal employees to access national healthcare solutions from the FUT Infrastructure their CPR information is required. The Infrastructure receive CPR for regional employees directly from SEB, however, for municipal employees, CPR must be obtained from Kombit FK Org. This is done through the internal OS2Sync service* running on the Infrastructure. OS2Sync uses BrugerService and PersonService version 6 of Kombit FK Org Version 3.2.

*The image used on the FUT Infrastructure can be found on dockerhub and the source code on GitHub OS2Sync.
