我们有一个用MVC4编写的现有系统，它使用SimpleMembershipProvider。它是使用WebSecurity.InitializeDatabaseConnection()方法初始化的。
我们需要使用单点登录方法将“又一个论坛”整合到我们的系统中。我们设法让它工作但现在我们遇到错误，特别是下面的错误，不支持ApplicationName（）方法。

根据Microsoft的文档http://msdn.microsoft.com/en-us/library/webmatrix.webdata.simplemembershipprovider.applicationname(v=vs.111).aspx，如果您使用此方法，则ApplicationName属性不可用。
是否可以在“其他”模式下使用SimpleMembershipProvider，或者迁移到ASP.NET成员资格提供程序，但仍保留系统中的现有用户？
