RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 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 "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". 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 "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-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.

Red Hat Product Errata RHBA-2016:2462 0 normal SHIPPED_LIVE authconfig bug fix update 2016-11-03 14:05:55 UTC

Description Tomas Mraz 2016-03-24 10:39:56 UTC 
Description of problem:
With the method chosen to write the /etc/sysconfig/authconfig file it's 
not possible to verify if the content has changed since the last run or 
not due to the fact of using a dictionary to store the key/value params 
and use iteritems over them.

a more reproduce able way is to instead of using iteritems from the dictionary a sorted list (see attached patch)


How reproducible:
as described above, everytime authconfig is called

this is what currently happens
$ md5sum /etc/sysconfig/authconfig 
93adf3e2b9272626064870d1a7ac1ace  /etc/sysconfig/authconfig
$ authconfig --updateall
$ md5sum /etc/sysconfig/authconfig 
571a51f178bc49f7db03993255110f45  /etc/sysconfig/authconfig
$ authconfig --updateall
$ md5sum /etc/sysconfig/authconfig 
6ac7ad67f313f8ce3250e8e56864b507  /etc/sysconfig/authconfig

this is what we are expecting
$ md5sum /etc/sysconfig/authconfig 
93adf3e2b9272626064870d1a7ac1ace  /etc/sysconfig/authconfig
$ authconfig --updateall
$ md5sum /etc/sysconfig/authconfig 
93adf3e2b9272626064870d1a7ac1ace  /etc/sysconfig/authconfig

Additional info:
there's an additional _truncate_ in the write section of the 
SHVFile which also make's it impossible to have a unique hash when 
deploying the plan file and afterwards calling "/usr/sbin/authconfig 
--updateall"
