Logoff from identity provider in sapui5 application in Sap cloud platform

Hello All,

I am using one identity provider for login service in Sap ui5 app in SCP. But, when iam trying to logout from the ui5 app, it is directly redirecting again to app without asking user credentials. I have tried the following approaches but they didn't work.

1) Maintaining logout Page in neo-app.json so that SCP will automatically take care of logout behavior- didn't work.

2) Tried with logout endpoint in user api service - didn't work.

3) Used below method (only from clear authentication Cache process and modifying url link to SAP CLOUD PLATFORM odata Services)-- didn't work.

Could you please provide your help here.

Thank you.

Are you testing it from WEB IDE or deployed cloud application?

I am testing the deployed application. I am also testing from web ide and it seems working fine in webide except that it is not displaying logout.html page and directly giving 503 error.

In deployed cloud app, it is displaying the logout page, but when I click log in again, it is directly starting the app without asking for credentials.

Use the following Approach:

1. Maintain the logout.html page in under webapp folder.

<!DOCTYPE HTML>
<html>
    <head>
        <script type="text/javascript">
          window.location.href = "./index.html"
        </script>
        <title>Page Redirection</title>
    </head>
    <body>
        <h4>Logging out...</h4>
    </body>
</html>

2. in neo-app.json, mention:

"logoutPage": "/logout.html",

3. In Controller, on the event, trigger logout page (Assuming your controller is also under controller folder in webapp folder):

sap.m.URLHelper.redirect("/logout.html", false);

Hi Anmol,

I have tried the above approach. Still, it is directly logging into the app after the logout page. I want to manually enter the credentials again when the user logs off.

Below is my logoff screen. when the user clicks on 'Log back on' button, it should redirect to IDP Providers login page. Yes, logout.html is under webapp folder only.

Strange. Working absolutely fine for me. You are using standalone app only? It is not on the Portal site right?

In my case, it is logging out and asking for the credentials again.

Yes. I am using standalone app only. No idea on why it is not working. Exploring the web to find any other solutions.

Can you share the snippet of your project structure, neoapp and controller code.

For a test purpose, can you try replacing your logout.html code with my given code once. I think there might be some issue with it. Secondly is it a HAT application? I can see the mobile folder in the project structure.

Yes. I have tried with the logout file you have. Still the behavior is same. Now, when click logout, it is directly starting the app as we have modified window.href

Yes. It is hybrid app. We are implementing app logout part separately.

Hi Anmol,

It is working now after deploying to cloud platform but not working when testing with webide.Not sure on why.

It is working fine with both the logout files(Your's and mine).

Thanks for your support here. Anything to say on not working in webide part?

Yes it won't work in webide because the path of logout file in webide is in webapp folder. If you want to make it work in webide, you need to mention the path with /webapp/ but as per the scenario, we will be using the deployed app in the production environment, not in webide.

Hope it helps.

Please upvote and mark the answer as correct if it helped.

Anmol

ok. Thank you. I have tried replacing with /webapp/logout.html and tested in webide. Still, it is directly redirecting into app.

Give a try by removing /webapp from neo-app only.

Maybe this will help: sap.ushell.Container.logout();
