When you access a Sybase Adaptive Server Enterprise database in PowerBuilder through Open Client, Sec_Network_Auth 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_Network_Auth controls whether your connection uses network-based login authentication. When Sec_Network_Auth is set to 1, your connection uses network-based authentication when connecting to a secure SQL Server. Network-based authentication means that the security mechanism—not the application—confirms that the specified user name represents the authenticated user running the application.
Since the security mechanism rather than the application authenticates your user name (login ID), you need not supply a login password for authentication purposes in the database profile or Application if Sec_Network_Auth is set to 1.
When Sec_Network_Auth is set to 0 (the default), your connection does not use network-based login authentication to connect to the server. You must specify a value for Sec_Network_Auth before connecting to the database in PowerBuilder.
Using third-party security mechanisms

mechanisms and operating system platforms that Sybase has tested

When to use Setting Sec_Network_Auth to 1 to enable network-based login authentication provides three important benefits for PowerBuilder users, because you do not have to specify a login password in the database profile or Application to authenticate the login ID when Sec_Network_Auth is set to 1:
Password not stored in registry file Since you do not specify a login password, no login password is stored in the Windows registry.
Password not transmitted across network Since you do not specify a login password, no login password is transmitted across the network to Adaptive Server.
Same user ID and password for different servers You can use the same network user ID and password to connect to many different Adaptive Server database servers. You can change your password for the network security mechanism and have this change apply on all servers to which your application connects.
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_Network_Auth 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_Network_Auth sets the corresponding Sybase CT-Lib connection property named CS_SEC_NETWORKAUTH.
To specify that your connection uses network-based login authentication when connecting to the server:
Database profile Select the Network Based Authentication check box on the Security page in the Database Profile Setup dialog box.
Application Type the following in code:
SQLCA.DBParm="Sec_Network_Auth=1;Release=15"
