By default, a new MVC project is configured to use the Membership Provider with SQLExpress using a file called aspnetdb.mdf in your App_Data folder. When you published, did that file make it to the destination?

To verify this is the issue, check your web.config. Look for the membership tag and the providers tag underneath that. Locate the AspNetSqlMembershipProvider provider and check its connection string. It will likely say ApplicationServices if you haven't changed it from the default. Then, check the ConnectionStrings node in your web.config to verify what database the Membership Provider is trying to use and where it's located.
