If you want to call the administration in the integration using single sign-on (SSO), you must configure the appropriate settings in the internet options of your operating system (individually or with group policies). You must add the d.velop documents base address in the internet options for the Local intranet security zone.
This is how it works
Open the Windows control panel and select Internet Options.
Go to Security and select Local intranet.
Click Sites > Advanced.
Under Add this website to the zone, add the d.velop documents base address and choose Add to confirm.
You can choose Custom level and go to User Authentication to define whether the login data is sent from the client PC to the server (SSO) or whether the user is asked for his or her user name and password. Automatic log in only in Intranet zone is enabled by default, which means that single sign-on should be enabled.
