Mendix Sso User Login Again After Refresh

IAM(Identity Access Management)

IAM or IdM(Identity Management) is a framework used to authenticate the user identity and privileges. It checks whether the users have admission to necessary files, networks and other resources that the user has requested. It too checks how and by whom the information can be accessed and modified past the management of descriptive information of users. IAM systems provide tools and some technologies to the administrators to modify a user's office, keeping rails on user activities etc.

Identity Management has four main basic functions:

The pure identity part: Without regard to admission or entitlements for identity creation, management, and deletion.
The user access(log-on) function: For example, to log-on to a service or services(a traditional view) the customer uses a smart menu and its associated information.
The service part: For user and their devices a system delivers personalized, role-based, online, on-need, multimedia(content) and presence-based services.
Identity Federation: To authenticate a user without knowing his/her password can be done by a organization using federated identity.

Single Sign-On

Single sign-on (SSO) is a property of access control for multiple related and contained software systems where user login with unmarried ID and password to gain access to a connected system/s without different usernames or passwords. SSO is typically achieved on Lightweight Directory Admission Protocol(LDAP) and stored LDAP databases on (directory) servers, an SSO can be achieved over IP networks using cookies but simply if the sites share a mutual DNS parent domain. Shared authentication schemes include OAuth, OpenID, OpenID Connect and Facebook Connect. All the authentication schemes which nosotros are using need user to log in their credentials every time they access a site or application, just we no need to get confused with SSO, in this single sign-on is enough to sign into dissimilar applications. By using SSO users tin enter their credentials in one case just always when they are signed.

Benefits of using SSO

Reduce risk for 3rd political party sites to access.
Reduce password debility from the different username and password combinations.
Reduce time spent for re-entering passwords for the same identity.
Reduce IT help desk-bound calls for passwords, therefore, IT costs are also reduced.

Keycloak

Keycloak is an open source identity and access management solution which mainly aims at applications and services. Users tin can authenticate with Keycloak rather than private applications. So, the applications don't accept to deal with login forms, authenticating users and storing users. Once logged-in to Keycloak, users don't have to login once again to access different applications. Aforementioned thing is applicative to sign-out. Keycloak offers everything a sophisticated user management tool needs – without having to log on repeatedly with every login and into every system-also equally arrangement security, social logins, support for mobile apps and integration into other solutions. Keycloak have implementations to LDAP and Active Directory every bit well.

Countersign Policies

Each new realm created has no password policies associated with information technology while users can create as short, as long, every bit complex, as insecure a password, equally they want. Simple settings are fine for development or learning Keycloak, but unacceptable in production environments.

OTP

Keycloak has a number of policies you can set up upwards for your FreeOTP or Google Authenticator One-Fourth dimension Password generator. There are 2 types:

TOTP(Time based OTP)
HOTP(Counter based OTP)

Customer Certificate

A client authentication certificate is a document used to authenticate clients during an SSL handshake, users who access a server by exchanging the client authentication certificate. A client certificate would typically incorporate pertinent data similar a digital signature, expiration date, name of customer, name of CA (Certificate Authority), revocation status, SSL/TLS version number, series number, and mayhap more, all structured using the X.509 standard. Very popular web browsers like Firefox, Chrome, Safari, and Internet Explorer can readily support client certificates.
If an awarding is enabled with client document hallmark, only users who try to connect from clients loaded with the correct client certificates will succeed. Even if a legitimate user attempts to connect with the right username and password, if that user isn't on a client application loaded with the right client document, that user will not exist granted admission. In fact, if that user's connecting from a Spider web browser, the login folio (where he's supposed to enter his username and password) might not even load at all like the ane shown below.
A server document is sent from the server to the customer at the start of a session and is used past the customer to authenticate the server. A client document, on the other hand, is sent from the client to the server at the start of a session and is used by the server to cosign the client.

Keycloak Working Procedure

On a complete organisation secured with keycloak:
A user clicks from a public page to navigate to protected area within the application. The link to this protected surface area is in the application settings in keycloak admin console.

The user will be redirected indeed to the keycloak authentication page. After providing username and password, keycloak redirects the user back to the application once more with a lawmaking that is valid to a very short span of time.
The application communicates this code to keycloak along with the application ID and the awarding hole-and-corner, and so keycloak replies with the Admission token, ID token, and a Refresh token. Your awarding will need only one of these tokens to run across which claims the user has, and according to the claims, the user will be granted or denied access to the requested protected URL(s).

Keycloak With OpenID Connect(OIDC)

OIDC is an hallmark protocol that is an extension of OAuth 2.0. OAuth 3.0 is merely a framework for building potency protocols, but OIDC is a full-fledged hallmark and dominance protocol. OIDC authentication menstruum when integrated with keycloak:

Browser visits application. The application notices the user is not logged in, so it redirects the browser to keycloak to exist authenticated. The application passes along a call-back URL(a redirect URL) equally a query parameter in this browser redirect that keycloak will utilise when it finishes authentication.
Keycloak authenticates the user and creates a one-time, very short lived, temporary code. Keycloak redirects back to the application using the call-back URL provided before and additionally adds the temporary lawmaking every bit a query parameter in the call-dorsum URL.

The awarding extracts the temporary code and makes a background out of band REST invocation to keycloak to exchange the code for an identity, admission and refresh token. Once this temporary lawmaking has been used to obtain the tokens, it tin never be used again. This prevents potential replay attacks.

Requirements
The tools that nosotros crave are mentioned below:
Operating systems: Windows, Docker
Tools: Maven
Single-Sign-On: Keycloak
Development environments: Eclipse
Programming Language : Java

Integrating multiple applications with keycloak

Add docker-compose.yml file and salve information technology in a binder.

Add keycloak and jump-boot dependencies.

CreateSecurityConfig.coffee file to your project.

Create applications.backdrop file.

Open control prompt and run docker-compose up to run keycloak.

Open browser and enter the keycloak url. Click on Administration Panel.

Default username and password is 'admin' , 'admin'.

Click on Add Realm. Give a proper name to the realm.

Add a customer.

Give the URL path of your awarding in valid redirect URL .

Add role.

Add user.

Go to credentials tab and reset password by giving new countersign.

Go to part mappings tab and add a office to the user.

Similarly create another application and add all the necessary files. In keycloak nosotros will use the aforementioned realm just we demand to add new customer, office and user.

At present run 2 applications

Open browser enter the url for showtime application.

When I click on products button, it will redirect to keycloak. Give username and password.

Now you lot will exist redirected to the application.

Now open up another tab and requite the URL for some other awarding. Yous will be redirected to the awarding without going to the keycloak login screen.
