Sec_Keytab_File – PB Docs 2022

Description

When you access an SAP Adaptive Server Enterprise database in
PowerBuilder through Open Client, Sec_Keytab_File 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_Keytab_File applies only to connections using Distributed
Computing Environment (DCE) Kerberos as their security mechanism and
requesting network-based login authentication. For those connections,
Sec_Keytab_File specifies the name of the keytab file containing the
security key for the DCE user.

You must set Sec_Keytab_File if the login ID specified in the
database profile or Application is different from the user name of the
DCE user currently running the application.

You must specify a value for Sec_Keytab_File before connecting to
the database in PowerBuilder.

Applies to

ASE, SYC SAP Adaptive Server Enterprise

Syntax

Default value

None

PowerBuilder does not set Sec_Keytab_File or the corresponding SAP
Sybase Open Client Client-Library (CT-Lib) connection parameter
CS_SEC_KEYTAB if you do not specify a value.

Usage

Supported only with Distributed Computing
Environment

Only Distributed Computing Environment (DCE) security servers and
clients support the use of keytab files. Therefore, Sec_Keytab_File is
supported only when your security mechanism is DCE Kerberos.

When to use

If you want your application to be able to connect to a server
with a different user name (login ID) than the DCE user currently
running the application, set Sec_Keytab_File to specify the name of the
keytab file containing the security key for the appropriate user. For
details, see the section called “Requirements for using Open Client security services” in Connecting to Your Database.

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_Keytab_File 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_Keytab_File sets the corresponding SAP
Sybase CT-Lib connection property named CS_SEC_KEYTAB.

Examples

To specify C:DCE_KEY as the name of the DCE keytab file:
