Sec_Delegation
database parameter
Description
When you access an SAP Adaptive Server Enterprise database in
PowerBuilder through Open Client, Sec_Delegation is one of several
parameters that support login authentication for network-based security
services. (For other login authentication parameters, see the See Also
section.)
For applications that are using network-based login authentication
to connect to an SAP Sybase Open Server gateway, Sec_Delegation controls
whether the gateway server is allowed to connect to a remote SQL Server
using delegated credentials. When Sec_Delegation is set to 1, the
gateway can connect to a remote server using the client’s delegated
credentials. The remote server must also be using network-based
authentication and an identical security mechanism.
When Sec_Delegation is set to 0 (the default), the gateway server
cannot connect to a remote server using delegated credentials.
You must specify a value for Sec_Delegation before connecting to
the database in PowerBuilder.
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.

security services in your PowerBuilder application. For details, see
the section called “Requirements for using Open Client security services” in Connecting to Your Database.
Corresponding CT-Lib connection
