Hey guys, Make sure to install gnutls-utils before attempting the same.

Unfortunately I would need a Gentoo ebuild of OpenSSL working with Apache 2.0 for things to work well. Dont think these ebuilds exist yet.

In this comment, Vasili Sviridov points to a website that uses a snapshot version of OpenSSL 0.9.9. Perhaps you could try to contact them too and ask for some info about how well that snapshot version works.

Tried commenting out the GnuTLSClientCAFile directive and still no dice. Wonder if there is any way to make this work without having to wait for mod_ssl 0.9.9 to be released supporting SNI? Tried contacting the author of mod_gnutls and have not received any response.

Indeed. I checked the list of the root certificates in FF2 and the startcom certificate is there. From the mod_gnutls documentation:
GnuTLSClientCAFile Takes an absolute or relative path to a PEM Encoded Certificate to use as a Certificate Authority with Client Certificate Authentication.
This means that the certificate that has been specified by the GnuTLSClientCAFile directive is only used for client autrhentication via a certificate and actually not when the client enters the secure mode in the browser. Perhaps you should try commenting out this directive and see if it works.

@ Jeremy: Thanks for those links about the SNI browser support. @George: It would work without any popups only if the root startcom certificate had been added to the list of trusted certificate authorities in the browser. I seriously doubt that firefox includes this root certificate by default. The user has to trust it first. IIRC, the same happens with certificates from

Has onyone tried using mod_gnutls in conjunction with startcom (free as in beer) certificates? I have set the GnuTLSClientCAFile directive and am still receiving an invalid certificate error in Firefox 2.0. This _should_ work without any popups whatsoever. Has anyone had any experience with this?

Unfortunately SNI support in browsers is limited to these: Firefox 2, IE 7 on Vista, Opera 7.6+ and other modern browsers. ( IE 6, lynx, safari and the like are not supported. (

I write this for other readers who run into issues: mod_gnutls requires the httpd and gnutls development libraries in order to compile.
