Configuring Kerberos authentication

Before you use Kerberos authentication to connect to Oracle on Linux or Windows, the organization administrator needs to perform the prerequisite tasks.

Create a JAAS configuration file on the Secure Agent machine.

Add the following entries to the JAAS configuration file:

ticket_lifetime = 24h

[realms]
<REALM NAME> = {
kdc = <Location where KDC is installed> 
admin_server = <Location where KDC is installed>
                                }
 [domain_realm]
<domain name or host name> = <Domain name or host name of Kerberos>
<domain name or host name> = <Domain name or host name of Kerberos>

Set the following environment variables on the Secure Agent machine.

For more information about the required environment variables, see Setting environment variables.
