I found out my problem was that our SSL certs were not being generated correctly.  Once the cert was set for SHA-256, and imported the ASA, the ASA displayed the correct algorithm.

any update on this?  were you able to resolve it are set the SSL VPN to SHA-256.  I have a similar issue.

I don't know the root cause, but I know upgrading the WLC to newer code fixed the problem for me.  We are now at 7.0.235.3 without incidents.

There was no bug ID from Cisco.  This was a problem I stated with my TAC engineer when he recommended upgrading to 7.0.235.3 to fix our wireless authentication problems, but there is nothing noting this resovle in the release notes.  We were on 7.0....

I am having the same issue with my clients.  Any other suggestions?  i tried fbarboza's suggestions, but no joy.
