Sec_Cred_Timeout – PB Docs 126

Sec_Cred_Timeout database parameter


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.

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 SAP Adaptive
    Server Enterprise





Specifies the number of seconds remaining
before a user’s network credentials expire and become invalid.
You can also specify 'no_limit' (the
default) to specify that the credentials not expire.

A credential timeout value set by the security system’s administrator
supersedes any value you specify for Sec_Cred_Timeout.




CyberSafe Kerberos

If your security mechanism is CyberSafe Kerberos, Sec_Cred_Timeout
cannot override the installation default value set for credential

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:
