I am trying to do anonymous PAC provisioning to some new 7921 phones with ACS 18.104.22.168.6.
I have created a user & pwd on the phone, and added this user to ACS.
I have configured the WLC, ACS & phone as per the 7921 deployment guide (though there are a few more options now in ACS 4.2).
When the phone tries to intially authenticate with ACS, I see failed logins on ACS for the user 'anonymous'. I assume that this is something to do with the PAC provisioning (phase 0 failure etc.).
But all I see is continuous login failures on ACS, and no PAC provisioning occurs.
Is there maybe some other setting I'm missing? Anyone else see a similar issue when trying to do this?
