Hi Adam,

 

I've confirmed that it's as follows:

 

    Public Overrides Function GetUserInfo(ByVal loginName As String, ByRef nickName As String, ByRef isAdmin As Boolean) As Boolean
        'return false , if the loginName is invalid.
        'otherwise set the nickName and isAdmin , and return ture
        nickName = "test"
        isAdmin = True
    End Function
