I'm doing this one on one project, and it works well:
// provide a readable user name, if there isn't one
HMI.currentUser := WSTRING_TO_STRING( VisuElems.CurrentUserName );
IF ( LEN( HMI.currentUser ) <= 0 ) THEN
HMI.currentUser := 'None';
END_IF
_loggedIn := ( HMI.currentUser <> 'None' );
Use _loggedIn as a Boolean variable driving a lamp/indicator state.
Good luck,
Mark

Don't forget to set the checkbox "Use CurrentVisu variable" in the General Settings of the Visualization Manager!
The UserGroupID's are shown in the Visualization Manager:
