If you want to enable Kerberos authentication and you do not want to use the default file, you need to provide information such as keystore and truststore directories. Each node needs to contain a keystore and truststore that is used by all services on that node.

The following table describes security information to provide during installation:

Security Information	Description
Service realm name	Name of the Kerberos realm to which the Informatica domain services belong. The realm name must be in uppercase. The service realm name and the user realm name must be the same.
User realm name	Name of the Kerberos realm to which the Informatica domain users belong. The realm name must be in uppercase. The service realm name and the user realm name must be the same.
Location of the Kerberos configuration file	Directory where the Kerberos configuration file named krb5.conf is stored. Informatica requires specific properties to be set in the configuration file. If you do not have permission to copy or update the Kerberos configuration file, you might have to request the Kerberos administrator to update the file.
Keystore file directory	Directory that contains the keystore files. The directory must contain files named infa_keystore.jks and infa_keystore.pem.
Keystore password	A plain-text password for the keystore infa_keystore.jks.
Truststore file directory	Directory that contains the truststore files. The directory must contain files named infa_truststore.jks and infa_truststore.pem.
Truststore password	Password for the infa_truststore.jks file.
