Sec_Cred_Timeout database parameter
Description
When you access an SAP 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.

Specifies the number of seconds remaining A credential timeout value set by the security system’s administrator |
Default
Sec_Cred_Timeout=’no_limit’
Usage
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.
Examples
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:
1SQLCA.DbParameter="Sec_Cred_Timeout=120;Release=15"
