Re: What is: 5770NAE *BASE 5050 Network Authentication Enablement -- MIDRANGE-L

Rob,

AFAIK, only "required" if you want to use Single-Sign-On and EIM. :-)

Thank you.
You'd think it would be mentioned as something required somewhere in here

Rob,
Google says:
IBM 5770-NAE, or Network Authentication Enablement, is an IBM i licensed
program that enables Kerberos authentication on IBM i systems. Kerberos is
a network authentication protocol that provides a secure and reliable way
to authenticate users and services across a network. With 5770-NAE, IBM i
can participate in a Kerberos realm, allowing users to authenticate with
their Kerberos credentials to access IBM i systems and applications.
- What is Kerberos?Kerberos is a network authentication protocol that
uses cryptography to authenticate users and services. It relies on a
trusted third party, the Key Distribution Center (KDC), to manage and
distribute keys.
- IBM i Network Authentication Enablement (5770-NAE):This licensed
program allows IBM i to function as a Kerberos client, enabling it to
participate in a Kerberos realm. It provides the necessary components for
IBM i to use Kerberos for authentication.
- Why use Kerberos with IBM i?Kerberos provides a secure and
centralized way to authenticate users and services, which is beneficial for
organizations that rely on IBM i for their business operations. It can be
used for single sign-on (SSO), allowing users to authenticate once and
access multiple resources without re-authenticating.
- How to configure Kerberos with IBM i:The configuration process
involves planning, installing 5770-NAE, and configuring the IBM i system to
connect to a Kerberos server (KDC). This includes defining the Kerberos
realm, configuring the KDC, and setting up keytab entries for IBM i service
principals.
- Key benefits of using Kerberos with IBM i:
- Improved security: Kerberos provides a robust authentication
mechanism that is resistant to various attacks.
- Centralized authentication: Users authenticate once with their
Kerberos credentials and can access multiple IBM i systems and
applications.
- Single sign-on (SSO): Users can access various resources without
repeatedly entering their credentials.
- Compliance: Kerberos

I believe this is something IBM cloned from AIX and installs in PASE.

My system says it is for V7R4 and I haven't ran that in years.
I realize that some products are skip ship and aren't always renewed with
each release but I cannot find any mention of this product.
