1. In Salesforce, from the App Launcher, choose the Dropbox application. If you configured the Dropbox logo and icon for the connected app, the App Launcher displays them. If identity provider–initiated SSO is configured properly, Salesforce creates an application session.
2. To test service provider–initiated SSO, enter the URL that you saved when you configured SSO, for example, https://www.dropbox.com/sso/11272027. When you are redirected to the Salesforce login page, enter your credentials. If SSO is successful, you are logged in to your Dropbox account.
