Single Sign On (SSO) allows an end-user to interact with multiple services without logging in more than once.

This page shows how to integrate UBIK^® into such an SSO environment.

Client

Instructions

The customer's Identity Provider must know UBIK^® as a Service Provider. In case of SAML, we need to provide an SSO mediator server in order to relay SAML responses for the client; this is our ACS (Assertion Consumer Service). In case of OIDC, the client app interacts with the OIDC provider directly.

There are two major use-cases for SSO:

Authentication: Establishing or re-using an SSO session (logging in)
Authorization: Interaction with external systems (interfacing)

In order to configure UBIK^® for SSO integration, we need to address both.

Authentication

In the UBIK^® client profile, adjust the SSO relevant settings (enabling SSO and specifying the Identity Provider Endpoint URL for an IdP-initiated flow).
On the server side, make sure that an SSO Processor is configured able to process the responses from the Identity Provider.

Authorization

When a UBIK^® object is synchronized between client and server, the UBIK^® customizing can interact with external systems. There, we might require authorization, and we need to make sure the client provides a respective token. In order to do so, we have to identify the specific authorization use-cases:

For which types of objects (meta classes) do I need to interact with external systems, requiring SSO authorization?
For which synchronization operations (e.g., update, commit, create, etc.) do I need authorization?
Which SSO client configurations (identity provider base URL, scopes, etc.) are used in this case?

For each resulting combination we have to create an External Auth Config object and give it to the client in the infrastructure list.

Further, we have to make sure the authorization tokens can be transported to the server. Therefore, add the External Entity Classification to all meta classes of objects that need external authorization.

Studio

Authentication

Install the Auth Processor plugin (SAMLProcessor or OIDCProcessor plugin) in your web service's injection folder
Customize your UBIK Context, overriding the method "GetSSOProcessor" so it returns an instance of the authentication processor:

public override UBIK.Kernel.SSO.ISSOProcessor GetSSOProcessor(System.String token)

	{
		string jwks = "...";
		return new UBIK.SSO.OIDCProcessor.OIDCProcessorExt(Environment, token, jwks);
	}
	return base.GetSSOProcessor(token);
}

You will need to insert the correct jwks from your OIDC Provider instead of "...".

public override UBIK.Kernel.SSO.ISSOProcessor GetSSOProcessor(System.String token)
{
	if (this.Name == "MyContextName")
	{
		byte[] certificate= null; // load from file
		return new UBIK.SSO.SAMLProcessor.SAMLProcessorExt(Environment, token, certificate);
	}
	return base.GetSSOProcessor(token);
}

You will need to load the correct certificate from your SAML Identity Provider instead of null. It's recommended to save the certificate on the server and load it from file storage. The certificate must be the one the IdP uses to sign its SAML responses with.

Authorization

Add External Auth Config objects to the client's infrastructure
Add the External Entity Classification to all affected meta class scopes

An external auth config object specifies for which meta class and sync action (e.g., when uploading instruction documents), which SSO configuration should be used. The result of a correct configuration will be, that the client sends an SSO token to the server when performing the sync action for an instance of the meta class. On the server side, you can use that token to interact with the external system. This only works if there is a scope with the external entity classification for that meta class, because it provides the means to transport the token.

Client

OIDC

Set up an identity provider if necessary
Assemble a client configuration JSON string, .e.g.:

{'AuthorityURL' : 'https://xamarinoidc-app.azurewebsites.net',
'ClientID' : 'gnabbermobileclient',
'ClientSecret' : null,
'RedirectURL' : 'oidcxamarin101:/authenticated',
'Scope' : 'openid profile',
'IsPivotEnabled' : 'false'}

Integrate client configuration in profile:

SAML

Set up an identity provider if necessary
Set up an SSO mediator backend server to relay SSO responses to the client

To set up an Authentication Mediator Server first go to http://release.augmensys.com/ and download the provided Zip File. After you downloaded the Zip create a new IIS applicatio (https://docs.microsoft.com/en-us/iis/configuration/system.applicationhost/sites/site/application/). Open the just created app in your file explorer, unpack the downloaded ZIP file and copy all files of that ZIP into the app-folder. If IIS prohibites you to copy files you need to first stop the server. After successfully copying the Files you need to Restart/Start the IIS server again. Now you have set up the Authentication-Backend and it is ready to use.

Assemble a client configuration JSON string, .e.g.:

{"AuthUser": "user", "AuthUserPw": "test", "BackendURL": "https://ubik.test.com/UBIK/DEV/AUTH_SERVICE/", "IdpURL": "https://idp.com/idpssoinit?metaAlias=ubik;spEntityID=ubik", "IdpLogoutURL": "", "IsPivotEnabled": false, "Env_Broadcast" : null, "Env_Data": null}
