[BUG] Cannot configure "azure" authorization client

[sgraca]

Describe the bug
In Spring Boot Starter for Azure, when the application is configured as web_application_and_resource_server it's not possible to configure scopes for azure authorization client.

Exception or Stack Trace

To Reproduce

• Include following dependencies in a Spring Boot application:

  implementation 'com.azure.spring:spring-cloud-azure-starter-active-directory:4.3.0'
  implementation 'org.springframework.boot:spring-boot-starter-oauth2-resource-server'
  implementation 'org.springframework.boot:spring-boot-starter-oauth2-client'
  

• Create a minimal application

  @SpringBootApplication
  public class WebAppApplication {
      public static void main(String[] args) {
          SpringApplication.run(WebAppApplication.class, args);
      }
  
      @EnableWebSecurity
      public class AzureSecurityConfiguration extends AadWebSecurityConfigurerAdapter {
      }
  }
  

• Add configuration properties in application.yml

  spring:
    cloud:
      azure:
        credential:
          client-id: <YOUR CLIENT ID>
          client-secret: <YOUR CLIENT SECRET>
        profile:
          tenant-id: <YOUR TENANT>
        active-directory:
          enabled: true
          application-type: web_application_and_resource_server
          app-id-uri: ${spring.cloud.azure.credential.client-id}
          authorization-clients:
            azure:
              authorization-grant-type: authorization_code
              scopes:
                - test-scope
  

Code Snippet
Given in the previous section.

Expected behavior
Application starts without errors.

Setup (please complete the following information):

• OS: macOs
• IDE: IntelliJ
• Library/Libraries:com.azure.spring:spring-cloud-azure-starter-active-directory:4.3.0
• Java version: 11
• App Server/Environment: Tomcat
• Frameworks: Spring Boot

Additional context
The issue seems to be caused by invalid value comparison in this line where the grantType property is compared by reference instead of using equals.

Hi @sgraca thank you for reaching out to us via this GitHub issue. Someone from the Azure Spring team will follow up with you shortly.

[yiliuTo]

Thanks @joshfree for helping triage it and @chenrujun could you help to take a look?

Hi, @sgraca

Thanks for reaching out.

I can't reproduce the problem by this sample.

The issue seems to be caused by invalid value comparison in this line where the grantType property is compared by reference instead of using equals.

No. For Enum type. equals and == are the same. Refs: https://stackoverflow.com/questions/1750435/comparing-java-enum-members-or-equals

Could you please debug your code, and check the actual value of grantType?

[sgraca]

Hi @chenrujun

Thanks for looking into this.

This might be related to the Spring version then. I'm using Spring Boot 2.7.1 with Spring Security 5.7.2. In this version AuthorizationGrantType is not an enum (see https://github.com/spring-projects/spring-security/blob/5.7.2/oauth2/oauth2-core/src/main/java/org/springframework/security/oauth2/core/AuthorizationGrantType.java).

The instance that is obtained from the configuration properties is not the same as the one defined as the constant in the class itself as it's created by calling the constructor with the value specified in the configuration. The values are the same and equals returns true but they are different instances.

@sgraca

I see. AadAuthorizationGrantType is enum, but AuthorizationGrantType is not enum. In #29471, AadAuthorizationGrantType is deprecated, use AuthorizationGrantType instead. So this problem happens. I'll fix this.

Thanks!
