1.5 Prerequisites/Preconditions

This protocol can be used after the client has discovered the server and established a network transport connection for use with TDS.

In the TDS 7.x version family, no security association is assumed to have been established at the lower layer before TDS begins functioning. In the TDS 8.0 version, such a security association is assumed.

For Security Support Provider Interface (SSPI) [SSPI] authentication to be used, SSPI support needs to be available on both the client and server machines. For channel encryption to be used, TLS/SSL support needs to be present on both client and server machines, and a certificate suitable for encryption has to be deployed on the server machine.

For federated authentication to be used, a library that provides federated authentication support or an equivalent needs to be present on the server, and the client needs to be able to generate a token for federated authentication.
