title: Web App Azure AD Authentication Sign Out going to No Page Found 404
body: <p>I am using a Web App for which I have implemented AD Authentication from the Authentication Tab in App Service. I have followed below link for Sigin and Signout functionality.</p>
  <p><a href="https://docs.microsoft.com/en-us/azure/app-service/configure-authentication-customize-sign-in-out" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/azure/app-service/configure-authentication-customize-sign-in-out</a></p>
  <p>I dont have any issues for Redirect URL : /.auth/login/aad/callback</p>
  <p>But when I use /.auth/logout for Signout, I am navigating to page Not found error.</p>
  <p>References I am using is Microsoft.Identity.Web</p>
  <p>(Based on my company Audit, we have to enable Authentication in App Service, while doing so it is expecting redirect url to be /.auth/login/aad/callback. So I have followed above url for this implementation).</p>
