Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

Hello Filip,

I spoke with Louise, and I will be responsible for this Release Note.

I have taken the Cause/Consequence/Fix text and worked it into the format we use, starting with the benefit. Could you please confirm that I have properly represented the issue?



Release Note Title:    MS-CHAP authentication with the OpenSSL legacy provider

Previously, FreeRADIUS authentication mechanisms that used MS-CHAP failed because they depended on MD4 hash functions, and MD4 has been deprecated in RHEL 9. With this update, you can authenticate FreeRADIUS users with MS-CHAP or MS-CHAPv2 if you enable the OpenSSL legacy provider.

If you use the default OpenSSL provider, MS-CHAP and MS-CHAPv2 authentication fails and the following error message is displayed, indicating the fix:

----
Couldn't init MD4 algorithm. Enable OpenSSL legacy provider.
----
