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.

Description lizzha 2016-03-17 06:47:03 UTC
We're going to implement password policy in the on-demand Azure RHEL images, to align with the password policy from Azure portal.

Here're the rules
- The password must be between 6-72 characters long.
- The password must contain 3 of the following:
  a lowercase character
  an uppercase character
  a number
  a special character 

We come out the below solution, could you please help review?

Add following lines in /etc/security/pwquality.conf
minlen = 6
dcredit = 1
ucredit = 1
lcredit = 1
ocredit = 1
minclass = 3

Comment 2 Tomas Mraz 2016-03-17 09:16:43 UTC
Again as libpwquality calls cracklib the configuration needs to be similar to RHEL-6 - that means this is the proper configuration:

minlen = 6
dcredit = 0
ucredit = 0
lcredit = 0
ocredit = 0
minclass = 3
