[Freeipa-users] FREAK Vulnerability

[Terry John]

Thanks for this. I've had a look today
We are running:

ipa-server.x86_64                             3.0.0-47.el6.centos

and some of the directives did not work, namely  allowWeakCipher, sslVersionMin  and sslVersionMax . So I commented them out
The ldapupdater then seems happy but when I went to restart IPA. The ldap server wasn't happy with cipher TLS_RSA_WITH_AES_256_CBC_SHA256 and would not start.

Now I can't change anything and it doesn't work. Reaching for my backup.....

Terry

Hi Terry,

you can give the attached file a try. It's a ldif file for ipa-ldap-updater. You need to run the command on the machine as root and restart 389-DS.

The hardened TLS configuration is highly experimental and comes with no warranty whatsoever. The configuration works on my tests systems with Python's ldap client and Apache Directory Studio. It may not work with other clients, especially older clients or clients in FIPS mode.
