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 VMware Identity Manager 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 VMware Identity Manager 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, VMware Identity Manager admin users enter the following URL to log in to the VMware Identity Manager console, <example.com>/SAAS/login/0. The user name and password screen is displayed.
