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 a 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 Sybase has tested
with Open Client security services, see the Open Client documentation.

Set Release parameter
For this parameter to take effect, you must also
set the Release parameter to 11or higher to specify that your application
should use the appropriate version of Sybase Open Client Client–Library
(CT-Lib) behavior. See the description of the Release parameter
for more information.
Requirements for use
To use Sec_Delegation or any other parameter supporting
Open Client security services, you must meet certain requirements for
using security services in your PowerBuilder application. For details,
see “Requirements for using Open Client security services” in Connecting
to Your Database.
Corresponding CT-Lib connection property
Specifying a value for Sec_Delegation sets the corresponding
Sybase CT-Lib connection property named CS_SEC_DELEGATION.
Examples
To allow the Open Server gateway to connect to a
remote server using delegated credentials:
-
Database profile
Select the Use Delegated Credentials check box on the Security
page in the Database Profile Setup dialog box. -
