First of all, you are using legacy Membership Provider. Here is the new ASP.NET Universal Providers which is backward compatible with legacy Membership Provider.
If you want the latest Membership Provider, you want to look at ASP.NET Identity which is not backward compatible with legacy Membership Provider.
Login failed for user 'admin'.
According to the error message, login credential for the SQL Server is not correct.
