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

I am using dell xps 13 with precise and my company is using Aruba AP,
which I am not able to connect to it through WPA2 enterprise.
And I don't see libssl1.0.0_1.0.0e-2ubuntu4 in "synaptic package
manager" anymore. So I am running libssl1.0.0_1.0.1-4ubuntu5.5.
I am using wpagui and wpasupplicant "0.7.3-6ubuntu3.gnutls1".
Please let me know if there is anything I can try to test.

Breaks 802.1x (PEAP) authentication for wireless networks using specific authentication servers and/or AP hardware. Aruba network devices specifically are known to be affected; and is a popular device type used in enterprises to secure wireless networks.
This issue is hardware specific and may or may not be limited to Aruba authentication servers.
1) Attempt to connect / authenticate to a wireless, 802.1x network requiring Protected EAP (or possibly other auth mechanisms).
2) (optionally) Watch SSL traffic between the station and authentication server using wireshark/tcpdump, looking for auth failures and the extensions passed.
Since this changes the SSL extensions and options used to connect to 802.1x wireless networks; some networks specifically configured to request or make use of the session ticket extension could be made impossible to successfully authenticate to; up to the point where multiple connection failures could lock the accounts used in highly-restricted networks. Also, there is a potential (again, due to the change in SSL options) for other networks (using specific AP hardware) that don't support the extensions used to fail authentication.
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:
