The setting Show the System Domain on Login Page is enabled by default in the Identity & Access Management > Setup > Preferences page. Users are presented with the domain drop-down selection menu that lists all Active Directory domains integrated with the Workspace ONE Access server and the local System domain.
If you deselect the Show the System Domain on Login Page setting, the System Domain entry is removed from the domain drop-down menu. When the Workspace ONE Access service contains a single Active Directory domain, users do not see the drop-down menu. They are prompted for their credentials to log in.
When the system domain is not displayed in a drop-down menu, Workspace ONE Access admin users enter the following URL to log in to the Workspace ONE Access console, <example.com>/SAAS/login/0. The user name and password screen is displayed.
