SFAuthorizationPluginView in the system.login.fus scenario.

Hello,

Regarding authorization plugins, I am trying to display a user interface in the fast user switching (fus) scenario. I have implemented the SFAuthorizationPluginView class that theoretically would help me show a user interface in this context. doing tests, I see that my plugin window is displayed behind the fus background screen. This window in screen lock scenario is displayed correctly. Is there any limitation in fus that prevents displaying a UI above the background screen where the user enters the password?

I show how I have system.login.fus configured(My plugin is MyTestPlugin):

... <key>mechanisms</key> <array>

<string>builtin:smartcard-sniffer,privileged</string>
<string>loginwindow:login</string>
<string>builtin:reset-password,privileged</string>
<string>builtin:auto-login,privileged</string>
<string>builtin:authenticate-nocred,privileged</string>
<string>MyTestPlugin:invoke</string>
<string>loginwindow:success</string>		
<string>loginwindow:done</string>

</array> ...

I have tried placing my puglin in a different order compared to other mechanisms and it did not get the window to display above the background screen. Another option I've tried is to place my plugin on top of loginwindow:login. In this case, my plugin interface is displayed correctly but I do not have username information. Is there a way to obtain this information?

All the best.
