title: Azure AD B2C with Spring 4
body: <p>I have Spring application with Spring Security version 3.2.5 and spring version 4.3.7.</p>
  <p>I want to remove the old fashioned login page and integrate it with Azure AD B2C. For the B2C part, I have the B2C tenant and necessary policies in place. I tried finding something on this for Spring, but all the examples and samples I found were based on spring boot.</p>
  <p>Is it feasible to achieve B2C authentication &amp; authorization integration with Spring?</p>
