Sec_Channel_Bind

database parameter

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.
