The following example will show you how to update it for AD User objects.
Open ADSIEdit
Click “Connect to” under the actions menu
Leave the defaults except select the well known naming context “Configuration”
Expand the Configuration Branch and select CN=DisplaySpecifiers container
Expand your language code CN=407 (for de-DE) other languages codes could be found at: https://support.microsoft.com/en-us/help/324097/list-of-language-packs-and-their-codes-for-windows-2000-domain-control
Click on CN=user-Display
Double click AdminPropertyPages and add the following value: 11,{c7436f12-a27f-4cab-aaca-2bd27ed1b773}
If you want to see the attribute flag on other objects you have to add 12,{c7436f12-a27f-4cab-aaca-2bd27ed1b773} to the AdminPropertyPages, like CN=organizationalUnit-Display or CN=computer-Display.
