The Business Data List Connector for SharePoint connects almost any on-premise or cloud-based data source, e.g. ODBC, OLEDB, OData, Microsoft .NET based providers, Files (Excel, XML, CSV), SQL databases like SQL Server, Oracle, MySQL, IBM DB2, IBM AS/400, IBM Informix, Notes, SharePoint, Exchange, Active Directory, Navision, SAP and many more directly to native SharePoint lists - in just minutes without any programming. But often there are issues to connect via web services (e.g. CSOM, OData) using SSL/HTTPS. This FAQ shows how to solve these general SharePoint (not BDLC related) issue.
