Red Hat Training

A Red Hat training course is available for Red Hat Enterprise Linux

3.2. Installing Kerberos

Kerberos packages may be installed by default, but make sure that the appropriate packages are installed for the Kerberos server or client being configured.
To install packages for a Kerberos server:
# yum install krb5-server krb5-libs krb5-auth-dialog
To install packages for a Kerberos client:
# yum install krb5-workstation krb5-libs krb5-auth-dialog
If the Red Hat Enterprise Linux system will use Kerberos as part of single sign-on with smart cards, then also install the required PKI/OpenSSL package:
# yum install krb5-pkinit-openssl
