Comment 24 Josip Vilicic 2022-05-13 23:54:10 UTC

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.
