When you access a Sybase Adaptive Server Enterprise database in PowerBuilder through Open Client, Sec_Cred_Timeout is one of several parameters that support login authentication for network-based security services. (For other login authentication parameters, see the See Also section.)
Some security mechanisms allow applications to set credential timeout values for connections that use network-based login authentication. Sec_Cred_Timeout specifies the number of seconds remaining before a user’s network credentials expire and become invalid. Users obtain network credentials when they log in to the network.
By default, Sec_Cred_Timeout specifies that there is no credential timeout limit—the credentials do not expire.
You must specify a value for Sec_Cred_Timeout 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_Cred_Timeout=value
Parameter |
Description |
|---|---|
value |
Specifies the number of seconds remaining
before a user’s network credentials expire and become invalid.
You can also specify A credential timeout value set by the security system’s administrator supersedes any value you specify for Sec_Cred_Timeout. |
Sec_Cred_Timeout='no_limit'
CyberSafe Kerberos If your security mechanism is CyberSafe Kerberos, Sec_Cred_Timeout cannot override the installation default value set for credential timeout.
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_Cred_Timeout 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_Cred_Timeout sets the corresponding Sybase CT-Lib connection property named CS_SEC_CREDTIMEOUT.
To specify 120 seconds (2 minutes) remaining before a user's network credentials expire:
Database profile Type 120 in the Credential Timeout box on the Security page in the Database Profile Setup dialog box.
Application Type the following in code:
SQLCA.DBParm="Sec_Cred_Timeout=120;Release=15"
