When using Adaptive Server on NT, you can enable the security services provided by NT LAN Manager to authenticate users, clients, and servers to one another.
Figure 8-1 shows a client application that is using LAN Manager to ensure a secure connection with Adaptive Server.
Figure 8-1: Establishing secure connections between LAN Manager and Adaptive Server
The secure connection between LAN Manager and a server can be used to provide a unified login to Adaptive Server. Through this login, the LAN Manager authenticates users once and does not require them to supply a name and password every time they log into Adaptive Server.
The secure connection also can support one or more of the following security services:
Message integrity to verify that data communications have not been modified
Replay detection to verify that data has not been intercepted by an intruder
Out-of-sequence check to verify the order of data communications
