Trouble with Cisco AnyConnect ikev2 - Unknown Received a IKE_INIT_SA request

Hi Guys

I am trying to configure Cisco AnyConnect 3.1.04.074 on a Mac OS X 10.8.5 with a ASA 5525x running 9.1.3 to work by esatablishing a IPsec VPN tunnel over Cisco Anyconnect.

I have configured a local  PKI and installed the appropiate certificates on the client machine to ensure that all devices trust each other. The SSL based VPN is working fine however when I attempt the IPsec connection I see the following error in the asa logs.

I have followed the documentation located here,

https://supportforums.cisco.com/docs/DOC-18960

and here
