Having an issue with the way that SharePoint External Content Types are authenticating to a SQL server table. Currently we have to enable NT Authority\Anonymous Login in the SQL database to allow the content to be loaded. Due to having Foundation, I can not set up a Secure Store. Is there another way to allow a particular SharePoint Group to have access to reading and writing to a connected database? We want this to be as secure as possible.
2 SharePoint Foundation 2010 SP2 w/ February CU Servers
1 External Database Server running SQL 2008R2
