Introduction
Blueriq (exposed) flows can be protected by setting allowed roles on them. When a flow is started that requires the user to have an explicit role, this (by default) will redirect the user to the Blueriq login page. This article describes how to configure the authentication mechanism in the runtime that is 'behind' the login page. The Java and .NET runtime have similar functionality but are configured in a different way.

The Blueriq Runtime deliveres an out-of-the-box in-memory authentication provider in Java and a DefaultProvider in .NET. These default implementations should be used for development purposes as they store the credentials in plain text on the filesystem. |
Java Runtime configuration
The Java Runtime reads the authentication configuration from Spring environment properties, under the covers Spring Security is used. In the Java Runtime one Spring Security AuthenticationManager bean named blueriqAuthenticationManager
is registered, defined in com.aquima.web.boot.SecurityConfiguration
. An anonymous authentication provider is added by default (hardcoded), this is used for anonymous access.
Blueriq supports an in-memory
authentication provider type and a customBean
authentication provider type for custom authentication needs. Multiple authentication providers can be chained. Every authentication provider must have a unique name, this name is also used in the auth-providers-chain
property to determine the order of the authentication providers in the chain.
Properties
Like all security properties, the authentication properties are prefixed with blueriq.security
. For every authentication provider a type must be specified, it can be in-memory
or customBean
.
Defining an in-memory
authentication provider
In the application.properties
file two properties are expected for an in-memory
authentication provider:
...
Code Block |

# format: USERNAME=PASSWORD,ROLE1,ROLE2 admin=welcome,dcm,administrator jane=welcome02,dcm,operator john=welcome03,dcm |
Defining a customBean
authentication provider
In the application.properties
file only one property is expected for a customBean
authentication provider:
...
Code Block |
---|
@Component public class MyCustomAuthenticationProvider implements AuthenticationProvider { @Override public Authentication authenticate(Authentication authentication) throws AuthenticationException { String name = authentication.getName(); String password = authentication.getCredentials().toString(); if (shouldAuthenticateAgainstThirdPartySystem()) { // use the credentials and authenticate against the third-party system return new UsernamePasswordAuthenticationToken(name, password, new ArrayList<>()); } else { return null; } } @Override public boolean supports(Class<?> authentication) { return authentication.equals(UsernamePasswordAuthenticationToken.class); } } @Configuration public class SecurityConfigurationMyAuthProviderConfig { @Bean public AuthenticationProvider myAuthProvider01() { return new MyCustomAuthenticationProvider(); } } |
Specifying which authentication providers to use
Only authentication providers specified in the blueriq.security.auth-providers-chain
property will be used by the Blueriq Runtime. The providers will be tried in the order they are specified in the chain. A warning will appear in the Blueriq Runtime log when no authentication providers are specified in the chain.

.NET Runtime configuration
The .NET Runtime reads the authentication configuration from Web.config
using the ASP.NET standard mechanisms for membership and role services. Blueriq has a DefaultMembershipProvider
and DefaultRoleProvider
that will read its users and roles from Web.config
sections.
