<html><body>Hello, We currently have 7 ipa servers in multi master running: ipa-server-3.0.0-47.el6_7.1.x86_64 389-ds-base-1.2.11.15-68.el6_7.x86_64 Tenable is showing the use of weak ciphers along with freak vulnerabilities. I have followed <a href="https://access.redhat.com/solutions/675183">https://access.redhat.com/solutions/675183</a> however issues remain in the ciphers being used. I have also modified dse.ldif with the following from <a href="http://freeipa-users.redhat.narkive.com/XGR9YzyN/weak-and-null-ciphers-detected-on-ldap-ports">http://freeipa-users.redhat.narkive.com/XGR9YzyN/weak-and-null-ciphers-detected-on-ldap-ports</a> With ipa stopped I modified dse with below odifyTimestamp: 20150420131906Z nsSSL3Ciphers: +all,-rsa_null_sha allowWeakCipher: off numSubordinates: 1 I turn on ipa and get Starting Directory Service Starting dirsrv: PKI-IPA...[27/Apr/2016:01:23:21 -0400] - Entry "cn=encryption,cn=config" -- attribute "allowweakcipher" not allowed So I go back into the file and allowWeakCipher now shows allowweakcipher (caps for W and C are now lower case) nss.conf # new config to stop using weak ciphers.
