Integrated Mode

In Integrated mode, SAP ASE uses Windows-based authentication mechanisms for all connections.

This is done by:

Allowing only trusted connections, using Named Pipes, to connect to SAP ASE.
Ignoring any SAP ASE login name and password that is submitted in the login request. Instead, it checks the mapped Windows network user name against the information in the syslogins table.

If no matching login name exists, and the login process includes a default user name, SAP ASE substitutes the default login name, for example, “guest”, to complete the connection.
Providing authorized users, when they log in, with permissions and roles.
Following the Windows Domain structure for the use of computers. Windows must authenticate each user, either through trust relationships or through explicitly assigned permissions on each server.

Note: If you bypass Windows login security for SAP ASE authentication, that is, if you opt for SAP ASE security only, it does not matter to which user or group you assign the computers. The only requirement is that the protocol you use allows the client and server to communicate.
