DS_Principal database parameter
Description
When you access an SAP Adaptive Server Enterprise database
in PowerBuilder through Open Client, DS_Principal is one
of several parameters that you can set to enable network-based directory
services in your application. (For other directory services parameters,
see the See Also section.)
Some directory service providers and drivers require an authenticated
principal (user ID) name to control an application’s access
to directory entries. For those providers and drivers, DS_Principal
and DS_Password specify the principal name and password
your application should use to identify you to the directory service
provider.
You must specify a value for DS_Principal before connecting
to the database in PowerBuilder.
Using third-party directory service providers
For information about the third-party directory
service providers and operating system platforms that Sybase has
tested with Open Client directory services, see the Open Client
documentation.

Default

PowerBuilder does not set DS_Principal or the corresponding
Sybase Open Client Client–Library (CT-Lib) connection parameter
CS_DS_PRINCIPAL if you do not specify a value.
Usage
When to use
If your directory service provider requires an authenticated principal
name for directory access, set DS_Principal to the principal
(user ID) name that goes with your directory service password.
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 DS_Principal or any other parameter supporting Open
Client directory services, you must meet certain requirements for
using directory services in your PowerBuilder application. For details,
see “Requirements for using Open Client directory services” in Connecting
to Your Database.
Corresponding CT-Lib connection property
Specifying a value for DS_Principal sets the corresponding
Sybase CT-Lib connection property named CS_DS_PRINCIPAL.
