Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Simon Reber 2018-04-04 06:17:01 UTC 
Description of problem:

The root password hash under Operating System (SHA256, SHA512, etc) are written in capital letters. This is saved the same way into `@host.operatingsystem.password_hash`. When using `Satellite Kickstart Default` we have `authconfig --useshadow --passalgo=<%= @host.operatingsystem.password_hash || 'sha256' %> --kickstart` which will fail and thus fall back to the default, as `authconfig` can't handle hash definition in capital letters.

> authconfig --passalgo=SHA512 --useshadow --kickstart
> authconfig: Unknown password hashing algorithm specified, using sha256.

Version-Release number of selected component (if applicable):

 - satellite-6.3.0.1-1.el7sat.noarch

How reproducible:

 - Always

Steps to Reproduce:
1. Select SHA512 in Operating System
2. Kickstart System with `Satellite Kickstart Default`
3. Check default password hash defined

Actual results:

> authconfig --passalgo=SHA512 --useshadow --kickstart
> authconfig: Unknown password hashing algorithm specified, using sha256.

Expected results:

> authconfig --passalgo=sha512 --useshadow --kickstart

We ran into the same issue. The workaround for us so far is

`authconfig --useshadow --passalgo=<%= @host.operatingsystem.password_hash.downcase || 'sha256' %> --kickstart`

Comment 6 Satellite Program 2018-06-27 16:13:20 UTC 
Moving this bug to POST for triage into Satellite 6 since the upstream issue http://projects.theforeman.org/issues/24084 has been resolved.
Comment 7 Lukas Zapletal 2018-07-26 09:29:39 UTC 
The fix was pushed into Foreman 1.19 and will be part of future Satellite version.

https://github.com/theforeman/community-templates/pull/487/files

The workaround is to fix kickstart template in Satellite:

-authselect --useshadow --passalgo=<%= @host.operatingsystem.password_hash || 'sha256' %> --kickstart
+authselect --useshadow --passalgo=<%= @host.operatingsystem.password_hash.downcase || 'sha256' %> --kickstart
Comment 10 Roman Plevka 2019-03-06 13:25:26 UTC 
VERIFIED
on sat6.5.0-18

the template already comes with .downcase:

# hammer template dump --id 46 | grep authconfig
authconfig --useshadow --passalgo=<%= @host.operatingsystem.password_hash.downcase || 'sha256' %> --kickstart

and renders properly
