Hi,

Long time since I last posted here. 4 years actually.

Anyway, I now work on the Certification team at the Linux Foundation. We offer LFCS (LF Certified System Administrator) and LFCE (LF Certified Systems Engineer) certifications. We also offer specialised certifications, such as COA (OpenStack), CKA (Kubernetes) and CFCD (Cloud Foundry).

The LFCS and LFCE can be taken on your distribution of choice (well, CentOS 7, Ubuntu 16.04 and openSUSE Leap 43). The major benefit is that whilst these exams are skills-based, live exams, they can be taken from the comfort of your own home on any machine with Chrome, a browser plugin, and a webcam, as they are remotely proctored, and you interact via Gate One (a browser-based terminal emulator).

Some of the competencies you complain about are in our exam competencies. These competencies are decided upon by a panel of diverse experts from the industry, of which I am a member. These are based upon the skills that are required in the modern environment, based upon extensive research in the industry.

Whilst the few people in this thread may not use SAMBA, iSCSI or Kerberos, there are a lot of people that do, and they are still relevant skills to possess. If you want to be certified as a Linux generalist, you should know how to do these things. If you didn't, there'd need to be specialised tracks to cater for employers looking for specific skills. Kerberos is rampant - FreeIPA for example - which I see in a great deal of places. Employers need to know that prospective employees have this core skillset.

Our exams are constantly reviewed, and updated as needed, in line with the ever-changing environment we find ourselves in. For example, we are actually refreshing LFCS and LFCE, due for release early next year (I am tech lead on that project, as well as COA and CKA).

Please note, I'm not trying to sell anything here, we are a not-for-profit organisation anyway.

Cheers
ZB

winbind_krb5_locator

WINBIND_KRB5_LOCATOR(7) 						 7						   WINBIND_KRB5_LOCATOR(7)

NAME

       winbind_krb5_locator - A plugin for MIT and Heimdal Kerberos for detecting KDCs using Windows semantics.

DESCRIPTION

       This plugin is part of the samba(7) suite.

       winbind_krb5_locator is a plugin that permits MIT and Heimdal Kerberos libraries to detect Kerberos Servers (for the KDC and kpasswd
       service) using the same semantics that other tools of the Samba suite use. This include site-aware DNS service record lookups and caching
       of closest dc. The plugin uses the public locator API provided by most modern Kerberos implementations.

PREREQUISITES

       MIT Kerberos (at least version 1.5) or Heimdal Kerberos (at least version 1.0) is required.

       The plugin queries the winbindd(8) daemon which needs to be configured and started separately.

       The winbind_krb5_locator.so file needs to be manually copied to the plugin directory of the system Kerberos library. For MIT Kerberos this
       is often: /usr/lib/krb5/plugins/libkrb5/. For Heimdal Kerberos this is often: /usr/lib/plugin/krb5/. Please check your local Kerberos
       installation for the correct paths. No modification in /etc/krb5.conf is required to enable the use of this plugin.

       After copying the locator plugin to the appropriate plugin directory it should immediately be available for use. Users should be able to
       kinit into their kerberized Windows environment without any modification or servers being put manually into /etc/krb5.conf.

VERSION

       This man page is correct for version 3 of the Samba suite.

AUTHOR

       The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.

       The winbind_krb5_locator manpage was written by Guenther Deschner.
