I am developing an application on Google App Engine in java using spring boot to test IDP SSO.
I am using saml2 with spring security. Google App Engine will act as an service provider and for IDP we will use another provider. I have a working demo on my localhost. https://localhost:8443/ takes to index.html. It has text (Hello world, guys!) and "launch SSO" button. When you click the button it redirects to IDP select page - https://localhost:8443/saml/discovery/alais/{keystore.key}?entityID={entityId}; where we can select the IDP and click login. When I deployed the app in Google App Engine flexible, the application loads correctly at https://{appTest}.appspot.com/ But when I click "launch SSO" button on the page, it is not redirecting to IDP select page - https://{appTest}.appspot.com/saml/discovery/alais/{keystore.key}?entityID={entityId} Instead it is redirecting to *http*://*ip Address*/saml/discovery/alais/{keystore.key}?entityID={entityId}. In logs, I see that it is getting redirected to http and port 80. Are there any properties I need to set for redirect to work properly on cloud? Please let me know if you have any suggestions. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
