Description
When you access an SAP Adaptive Server Enterprise database in PowerBuilder through Open Client, Sec_Server_Principal is one of several parameters that support login authentication for network-based security services. (For other login authentication parameters, see the See Also section.)
Sec_Server_Principal specifies the principal name of the server that you want to access. The server principal name is the name by which your security mechanism identifies each server.
If the server name (specified in the database profile or Application) is different from the server principal name for the server you want to access, you must set Sec_Server_Principal to the correct server principal name in order to connect.
You must specify a value for Sec_Server_Principal 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.
Applies to
ASE, SYC SAP Adaptive Server Enterprise
Syntax
Sec_Server_Principal='server_principal_name'
|
Parameter |
Description |
|---|---|
|
server_principal_name |
Specifies the principal name of the server you want to access |
Default value
None
If you do not specify a value, the security mechanism uses the server's directory entry name, which is the same as the server name specified in the database profile or Application.
Usage
When to use
When you use Open Client security services with PowerBuilder, the server's directory entry name (which you specify as the server name in the database profile or Application) might differ from the server principal name. In this case, you must set Sec_Server_Principal to the correct server principal name so that the security mechanism can identify the server you want to access.
Set Release parameter
For this parameter to take effect, you must also set the Release parameter to 11 or higher to specify that your application should use the appropriate version of SAP Sybase Open Client Client-Library (CT-Lib) behavior. See the description of the Release parameter for more information.
Requirements for use
To use Sec_Server_Principal 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 the section called “Requirements for using Open Client security services” in Connecting to Your Database.
Corresponding CT-Lib connection property
Specifying a value for Sec_Server_Principal sets the corresponding SAP Sybase CT-Lib connection property named CS_SEC_SERVERPRINCIPAL.
Examples
To specify SYS12NT as the principal name of the server you want to access:
-
Database profile
Type SYS12NT in the Server Principal Name box on the Security page in the Database Profile Setup dialog box.
-
Application
Type the following in code:
SQLCA.DBParm="Sec_Server_Principal='SYS12NT';Release=12"
