NSS does not fully implement support for server-side SNI currently. Most of the work has been done upstream, but it is not complete. There are details on the current state of the patches in the upstream bug:
We have had requests for SNI support for mod_nss, as it's needed to support name-based virtual hosts in Apache httpd. SNI would also be very useful for Red Hat Identity Management (IPA) and Red Hat Directory Server (389 DS).
We know this is still an upstream feature request. I am moving this to a 7.0 bug. It will be some time before we have any time to try to address this. For now, this RHEL bug will be dormant until the upstream bug has made more progress.
