Description John Dennis 2014-10-22 16:29:11 UTC
+++ This bug was initially created as a clone of Bug #1154776 +++

Description of problem:

The old protocol API for NSS allows only SSL2, SSL3 and TLS1.0. A new API was added to specify the min/max of the allowed range, SSL_VersionRangeSet. We need that in order to be able to enable the client to use TLS v1.1 and TLS v1.2

Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. Install IPA server
2. Update /etc/httpd/conf.d/nss.conf and set NSSProtocol to TLSv1.1
3. ipa -vv user-show admin

Actual results:

(SSL_ERROR_PROTOCOL_VERSION_ALERT) Peer reports incompatible or unsupported protocol version.

This is because only SSL3 and TLSv1 are enabled by default and there is no mechanism to enable them.

Rob, there is a Fedora scratch build here for a trial 0.16.0 version:


It includes all the SSL version range API calls (as well as the ability to set trust properites on Certificates that someone else had requested). Examples of using the SSL version range stuff can be found in doc/examples/ssl_version_range.py

I'd rather not go through the effort of doing an official Mozilla release and RHEL builds until you sanity check this trial version. Would you please do that and report back? Thanks!
