The ADFS agent includes a custom WatchGuard theme to set the appearance of the ADFS login page. The ADFS agent does not use this theme by default in case you have already set a custom theme.
To use the WatchGuard theme, run this PowerShell command :
Set-AdfsWebConfig -ActiveThemeName WatchGuardTheme
When you uninstall the AuthPoint ADFS agent, the theme that defines the appearance of the ADFS login page is set to the default. If you use a custom theme, you must run this PowerShell command to set your theme as active:
Set-AdfsWebConfig -ActiveThemeName <your theme name>
