[Bug 969343] Re: Unable to connect to WPA enterprise wireless

[Diane Trout]

I'm pretty sure the problem I had with connecting to my 802.1x network
had something to do with one of the new TLS extensions that was enabled.
It was pretty clear gnutls's TLS support isn't as complete as openssl's
(fewer extensions, fewer supported ciphers).  My packet inspections
showed the version of openssl that shipped with 12.04 enabled several
new extensions when compared to the 11.10 version of openssl or gnutls.

It'd be useful if there was a version wpasupplicant that would allows
easily changing which extensions are enabled so we can see which access
points support which extensions.

Would it be too obnoxious to add a configuration option to wpa
supplicant that allows manually twiddling flags on the
SSL_set_options(conn->ssl, options); call? Or would it be better to come
up some test tool that can test the various combinations of extensions
with 802.1x authentication?

Bug description:
  Using identical settings as in 11.10, I am unable to make a wpa
  enterprise connection using xubuntu precise beta 2. This is a Lenovo
  X220 with a Centrino Advanced-N 6205 wireless interface. During the
  attempted logon, I am not presented with a certificate to approve,
  although wireless instructions for OSX suggest that I should be.
  However, I never had to approve a certificate when connecting with
  11.10 -- I just ignored the certificate screen and everything worked.

  This seems like the relevant excerpt from syslog:
