Use the KRB5_CONFIG environment variable to store the path and file name of the Kerberos configuration file. The name of the Kerberos configuration file is

krb5.conf

. You must set the KRB5_CONFIG environment variable on each node in the Informatica domain.

Set the KRB5CCNAME environment variable with the path and file name of the Kerberos user credential cache. Kerberos single sign-on requires Kerberos credential cache for user accounts.

When you cache the user credential, you must use the

forwardable

option. For example, if you use

kinit

to get and cache the user credential, you must use the

-f

option to request forwardable tickets.
