Hi Martin and Nathan,
Thank you for providing that info.
Unfortunately, my IPA server is running on CentOS, and the latest IPA version
available through YUM is - 'ipa-server.i686 3.0.0-37.el6'.
The latest version of 389-DS through YUM is - '389-ds-base.i686
Nessus scan had detected this null cipher -
NULL-SHA Kx=RSA Au=RSA Enc=None
I found 2 'dse.ldif' files on disk -
In each of them, I found this -
So to disable null cipher, I removed 'rsa_null_md5' from that list -
I restarted the entire IPA stack, and ran the scan again, I am still seeing
that Null Cipher.
Any ideas on how to resolve this?

You can also check the FreeIPA counterpart:
This issue is fixed in FreeIPA 4.0.3 (available in Copr build and Fedora 21+),
we would very much welcome if you can verify that this setup works for you!
