When you access a Sybase Adaptive Server Enterprise database in DataWindow Designer 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 DataWindow Designer.
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.
SYC Sybase Adaptive Server Enterprise
DS_Principal = 'principal_name'
Parameter |
Description |
|---|---|
principal_name |
The principal (user ID) name your application should use to identify you to the directory service provider. |
None
DataWindow Designer 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.
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 DataWindow Designer 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.
To specify JSMITH as your application's principal name:
Database profile Type the following in the Principal Name box on the Directory Services tab in the Database Profile Setup dialog box:
JSMITH
Application Type the following in code:
SQLCA.DbParameter = "DS_Principal = 'JSMITH'"
