If you run the Informatica domain with Kerberos authentication, you must associate Kerberos service principal names (SPN) and keytab files with the nodes and Administrator Daemon. VDS requires keytab files so that services can be authenticated without being prompted for passwords. to generate keytab files, use the SPN and keytab file formats.
The following table describes the SPN format and the keytab file names for the VDS components:
Keytab File Name
admind/<isp domain>@<realm name>
node/<isp domain>@<realm name>
_AdminConsole/<isp domain>@<realm name>
To configure Kerberos authentication for VDS, generate keytab files for the Administrator Daemon and the VDS Node. To configure Kerberos authentication between the Administrator Daemon and the Administrator tool, generate keytab files for the Administrator Daemon, the VDS Node, and the Administrator tool.
The keytab files for VDS components must be available on the machines that host the component. During installation, you can specify a directory on the machine to store the keytab files. The installer picks up the keytab files from the keytabs directory you provide during installation.
After installation the Administrator Daemon keytab file is stored in the following directory:
The VDS Node keytab file is stored in the following directory:
The Administrator tool keytab file is stored in the following directory:
