Introduction

• The JS7 - Identity Services offer management of user accounts for authentication and authorization.
• The OIDC Identity Service integration is available from JOC Cockpit:
  • As a prerequisite JOC Cockpit has to be set up for JS7 - JOC Cockpit HTTPS Connections.
  • OIDC compliant Identity Providers can be used for authentication, for example Microsoft Azure®.
  • JS7 implements a client for use with OIDC Identity Providers. JS7 does not ship with an OIDC Identity Provider.
• FEATURE AVAILABILITY STARTING FROM RELEASE 2.5.0
  • JOC-1525 - Getting issue details... STATUS

Terminology

The OIDC protocol knows of the following roles involved in authentication:

• The Identity Provider is a system external to JS7 that provides authentication services for user accounts.
• The Client is the JOC Cockpit GUI that performs login/logout with the Identity Provider and that receives tokens from the Identity Provider in case of successful login.
• The Application is the JS7 - REST Web Service API that is handed over a token by the Client and which verifies the token with the Identity Provider.

Identity Service Type

The following integration level is available from the OIDC Identity Service Type:

Explanation:

• Service Type: OIDC-JOC
  • Management of user accounts with passwords is performed by the OIDC Identity Provider
  • The assignment of roles to user accounts is performed by the JOC Cockpit Application.
    • This is provided by the Accounts View where the a the roles are assigned to the known accounts .
  • The JOC Cockpit stores user accounts and role assignments: in the JS7 - Database.
  • The JOC Cockpit does not know passwords of user accounts or the access tokens of successful authentication.
• Service Type: OIDC
  • Management of user accounts with passwords is performed by the OIDC Identity Provider
  • The assignment of roles to user accounts is performed by the JOC Cockpit Application.
    • The accounts view is not provided when using OIDC 
    • The assignment of roles to accounts is provided by the group roles mapping editor in the "Manage Settings View" of the OIDC Identity Service.
  • The JOC Cockpit does not store user accounts and role assignments. This is done by the the OIDC Identity Provider
  • The JOC Cockpit does not know passwords of user accounts or the access tokens of successful authentication.

Group roles mapping

Roles are assigned to accounts via the editor for assigning group roles in the "Manage settings" view of the OIDC identity service.

A list of claims containing the groups configured in the OIDC provider can be defined. The available claims can be checked by checking the JW token during registration.

During assignment, the groups from the OIDC provider are assigned to the roles defined in the identity service. Any number of roles can be assigned to each group. 

Identity Service Configuration

The  icon in the JOC Cockpit main menu is used to select the Manage Identity Services page:

Add Identity Service

To add an Identity Service use the button Add Identity Service from the page shown above, listing the available Identity Services:

The remaining input fields for the popup window look like this:

Explanation:

• The Identity Service Name is a unique identifier that can be freely chosen.
• The Identity Service Type can be selected as available from the above matrix.
• The Ordering specifies the sequence in which a login is performed with available Identity Services.
• The Disabled attribute specifies if the respective Identity Service should not be considered by JOC Cockpit.
• The Identity Service Authentication Scheme allows to select
  • single-factor authentication: user account and password are specified for login with the Identity Service.
  • two-factor authentication: in addition to user account and password a Client Authentication Certificate is required - see the JS7 - Certificate based Authentication article for more information.

Identity Service Settings

Having added an OIDC Identity Service, it is necessary to add settings for the OIDC integration from the Identity Service's Manage Settings action menu item:

For use with the OIDC Identity Service Type:

• the OIDC Identity Provider product has to be accessible for JOC Cockpit and
• a number of settings have to be specified

Example for Keycloak

Example for Azure

Explanations:

OIDC Login

Once OIDC Identity Services have been configured they are displayed in JOC Cockpit's login screen like this: 

Explanation:

• OIDC Identity Services are displayed in alphabetical order.
• If a users clicks the Identity Service in the login screen then the Identity Provider will show a popup window that asks for credentials or the user will be immediately authenticated in case of single sign-on.

OIDC Flows

Register Client

It is necessary for a Client to be registered with the Identity Provider. The Client specifies the given Client ID and Client Secret during authentication. To achieve this, the token endpoint is called with:

• client-id: The Client ID which is configured in the JOC Cockpit Identity Service.
• client-secret: The Client Secret which is configured in the JOC Cockpit Identity Service.
• redirect-urls: The list of allowed URLs for redirection after authentication by the Client. Note that the URL of each JOC Cockpit instance has to be specified for clustered JOC Cockpit instances. For JOC Cockpit, the protocol (HTTP, HTTPS), host and port is specified as the URL, for example https://joc-2-0-primary:4446.

Registration of the Client is performed once in the lifetime of an OIDC Identity Service.

Authenticate Client

When authentication is performed with an Identity Provider then:

• no additional required Identity Services will be considered by JOC Cockpit. Authentication is performed with the given OIDC Identity Service only.
• OIDC Identity Services cannot be set to be required.

If the Client has previously authenticated with the Identity Provider and an active session exists then the Client immediately receives tokens from the Identity Provider. Without previous authentication the Client specifies credentials for authentication with the Identity Provider and creates a session in the Identity Provider. This mechanism allows Single Sign-On for Clients.

The Identity Provider returns the following to the Client after successful authentication:

• Access Token: The Client stores this token in a locker for later token renewal.
• Refresh Token: The Client stores this token in a locker for later token renewal.
• ID Token: This token is used by the Application to verify the Client's authentication. 

Verify Token

During login the following tokens are returned to the Client:

• Access Token: A token returned after successful authentication by the Identity Service Provider.
• ID Token: A JWT Token with Header.Payload.Signature is expected that is used by the Application to verify the Client's authentication.
• Refresh Token: A token used by the Client to renew the Access Token.

After successful login of the Client the OIDC Token Verification URL is called by the Application with the following settings:

• Client ID
• Client Secret
• ID Token

Processing of the response and verification of the token is performed by the following steps:

• Checking if the response contains the field "active". The value of the field is expected to be "true".
• Checking if the ID Token has not expired.
• Checking if the Client  ID (aud) stored in the ID Token is the same as in the configuration of the Identity Service.
• Checking if the issuer (iss) stored in the ID Token is the same as the OIDC Authentication URL in the configuration of the Identity Service.
• Checking if the account (e-mail) stored in the ID Token is the same as in the field "email" in the answer of the userinfo endpoint.
• Checking if the signature is valid for the given public key. The certs endpoint is the value of jwks_uri  in the response to the /.well-known/openid-configuration call. The response of the certs endpoint includes a number of keys. The public key is calculated from the key entry using the value for n and e of the corresponding array element where the kid value matches the kid in the token header. 

Renew Token

Access Tokens and ID Tokens include an expiration date. The tokens will be renewed by the Client 20s before expiration. 

If the tokens cannot be renewed, for example if the underlying session in the Identity Provider is terminated, then the JOC Cockpit session will be terminated and the user is forced to login. This occurs in case that:

• the session has been terminated in the Identity Provider. 
• no valid Access Token is returned from the Identity Provider.

The Client will use the following configuration items for token renewal:

• client-id: The Client ID that is configured in the JOC Cockpit Identity Service.
• client-secret: The Client Secret that is configured in the JOC Cockpit Identity Service.
• grant-type: refresh_token
• refresh-token: The Refresh Token that was previously returned by the Identity Provider after successful authentication..

The JOC Cockpit Session Idle Timeout is configured in the JOC Cockpit global settings for Identity Services. If the session in the Identity Provider is no longer valid then the JOC Cockpit session will terminate at the point in time of the next token renewal.

Single Sign-On

The OIDC Identity Service allows single sign-on for the underlying Identity Provider:

• Users who previously have been authenticated with the same Identity Provider as used by the OIDC Identity Service can access JOC Cockpit from their browser without specifying credentials.
• Users who initially authenticate with an Identity Provider by use of JOC Cockpit can open additional tabs in their browser without specifying credentials.
  • If a session is created for a user in the Identity Provider by authentication with JOC Cockpit then this session will last as long as the JOC Cockpit session.
  • If the user's Access Token is revoked in the Identity Provider then the underlying session in the Identity Provider will be continued until the JOC Cockpit session has been terminated either by a logout operation or by reaching the Idle Session Timeout.
  • If the user performs a logout operation from the JOC Cockpit session that was used to authenticate with the Identity Provider then the underlying session in the Identity Provider will be terminated.
