Hello,

probably IPA upgrade did this change

if you need custom ciphers to be preserved, you have to put your own 
upgrade file (number must be higher than 20) to IPA 
'/usr/share/ipa/updates/'

something like:

$ cat 99-myciphers.update

dn: cn=encryption,cn=config
only:nsSSL3Ciphers: default
only:allowWeakCipher: off


update default value with your own required ciphers
