Connecting Microsoft SQL Server with SSL protection and Kerberos authentication to propagate user ID without the need to reenter the password multiple times.
Secure Sockets Layers (SSL) is a standard that provides confidentiality and integrity to a TCP/IP transport, such as the one that the ODBC driver uses to communicate with an SQL Server instance.
Kerberos is a protocol that is devised by MIT to allow resources to be secured through a trusted third party (The Kerberos KDC). When the protocol is implemented by Microsoft, it can be used only to secure access within a complete active directory domain.
