In your identity provider (IdP) configuration, there is an advanced section with the setting Post logout redirect URI. By using the post logout setting, you can redirect a user who is logging out from the IdP to a URI of your choice. Without a post logout redirect, a user who logs out normally ends up on the home page of the identity provider.
In the following procedure, it is assumed that you are editing an existing IdP configuration.
Do the following:
In the Management Console, open the section Identity provider.
Select your identity provider and click Edit.
The page for editing the IdP configuration opens.
Scroll down to the bottom and open the section Advanced options.
For Post logout redirect URI, enter the URI to which you want to redirect the user after they have logged out from the IdP.
Allowlist the logout URI in your identity provider. The name may be Allowed Logout URLs, Logout redirect URIs, or something similar.
