Basic HybridRealm authentication. The PASOE validates the provided credentials (username & password) directly, through HybridRealm, using the ISwatAuthenticationService.

...

Front-end - Back-end interaction:

Logic-flow:

1. The client sends POST request with AD credentials to the "/web/Login/Login.html" access-point on the PASOE (swat-backend).
2. PASOE forwards AD credentials to the "/auth/ad/login" on the NodeJS (node-main).
3. NodeJS handles AD authentication, using passport with passport-ldapauth strategy. Then responds with ssoSessionId & ssoUserId.
4. PASOES passes back to Client the ssoSessionId & ssoUserId.
5. Client logins into PASOE, with ssoUserId & ssoSessionId, through HybridRealm.
6. PASOE HybridRealm handles login using ISwatAuthenticationService, which sends POST request to "/sessions", with ssoSessionId & ssoUserId, on the NodeJS.
7. NodeJs responds back to PASOE with the session's validity.
8. PASOE finalizes authentication process.
9. Client is authenticated.

In order to use HybridRealm as the authentication provider of spring.security, the following configuration settings must be set:

oeablSecurity.properties

• http.all.authmanager - Authentication manager to use, in our case: oerealm
• client.login.model - Authentication model to use, in our case: form
• OERealm.UserDetails.realmClass - OERealm (HybridRealm) class to use, in our case: Akioma.Security.HybridRealm 

Unauthenticated routes

To define routes that do not require authentication, by-passing altogether HybridRealm, modify the oeablSecurity.csv configuration file and set the desired URIs to permitAll():

Example for LoginWebHandler /web/Login/ routes:

# "url-pattern","<method>","<spring-access-expression>"
??
# Permit unauthenticated access to /web/Login/**
"/web/Login/**","*","permitAll()"
??
# Authentication for /web/**
"/web/**","*","hasAnyRole('ROLE_PSCUser')"
??
# Best practice - deny anything not explicitly granted
"/**","*","denyAll()"
