Configuring the HCL Informix® instance for SSOComplete the following tasks for the server side of your system to enable SSO functionality with HCL Informix®:
Ensure keytab file has the required key (UNIX™ and Linux™)Add the service principal key generated in the Key Distribution Center to the credentials information stored in the keytab file on the Informix® host computer, and then validate that all necessary credentials are stored in this file.
The keytab file (UNIX™ and Linux™)All Kerberos server computers on UNIX™ and Linux™ must have a keytab file to authenticate with the Key Distribution Center.

The keytab file (UNIX and Linux)

All Kerberos server computers on UNIX™ and Linux™ must have a keytab file to authenticate with the Key Distribution Center.

A keytab file is an encrypted copy of the Informix® service key. This file must be on the computer hosting Informix so that the DBMS can authenticate with the Key Distribution Center (KDC) and can accept the client's security context.

For instructions on adding a key to the keytab file, see the documentation provided with the Kerberos product.
