I've been trying to tidy the security on my FreeIPA and this is
causing me some problems. I'm using OpenVAS vulnerability scanner and
it is coming up with this issue

EXPORT_RSA cipher suites supported by the remote server:
TLSv1.0: TLS_RSA_EXPORT_WITH_RC4_40_MD5 (0003)

It seems we have to disable export  TLS ciphers but I can't see how. I've 
edited /etc/httpd/conf.d/nss.conf and disabled all SSL and TLSV1.0.

NSSCipherSuite -all,-exp,+<the ones I want>

I've restarted httpd and ipa but it still fails

Is there something I have overlooked

Hi Terry,

Please check

We are trying to come up with a better cipher suite right now. The fix should 
be in some of the next FreeIPA 4.3.x versions.

The ticket has more details in it.

Thanks for the info. I have tried nearly all the NSSCipherSuite settings in 
that ticket but none so far has eliminated the FREAK report.
Christian thanks for the heads up on the syntax, I wasn't sure of what I was 

Each time I've made a change I've run an sslscan from the OpenVAS scanner and I 
do get a different result each time but the errors still remains in OpenVAS.
Aaargh! Just noticed the port is 636/tcp(!) which is ns-slapd.

Just for the record, 389 Directory Server cipher suites for 636 were much improved in
i..e FreeIPA 4.0.3+ (and RHEL/CentOS 7.1 too).

So that port should not use any really unsecure ciphers any more.

Back to the drawing board :-)
