Description
When you access an SAP Adaptive Server Enterprise database in PowerBuilder through Open Client, Sec_Channel_Bind is one of several parameters that support login authentication for network-based security services. (For other login authentication parameters, see the See Also section.)
Sec_Channel_Bind controls whether your connection's security mechanism performs channel binding. When Sec_Channel_Bind is set to 1, both SAP Sybase Open Client Client-Library (CT-Lib) and the server provide a network channel identifier to the security mechanism before connecting. The channel identifier contains the network addresses of the client and server.
When Sec_Channel_Bind is set to 0 (the default), no channel binding is performed.
You must specify a value for Sec_Channel_Bind before connecting to the database.
Using third-party security mechanisms
For information about the third-party security mechanisms and operating system platforms that has been tested with Open Client security services, see the Open Client documentation.
