When you access a Sybase 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.
ASE, SYC Sybase Adaptive Server Enterprise
Sec_Delegation=value
Sec_Delegation=0
Not supported with CyberSafe Kerberos Sec_Delegation is not supported if your security mechanism is CyberSafe Kerberos.
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.
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.
Application Type the following in code:
SQLCA.DBParm="Sec_Delegation=1;Release=15"
