Auth-Type in post-auth SQL insert

[Brad Robel-Forrest <brad@altusnetworks.com>]

I'm pretty new to FreeRADIUS so I apologize if this is a really basic  
question. I've searched around quite a bit and have been unable to  
locate an answer.

I've successfully configured FreeRADIUS to use a SQL driver for  
authentication checks as well as inserting records via the post-auth  
query. Is there a runtime variable that I can reference to save the  
Auth-Type used for authenticating the user during post-auth? I've  
tried what I thought to be the obvious (e.g. %{Auth-Type}) but that  
doesn't seem to be available (just inserts an empty string).  
Essentially, I'd like to catalog the type of authentication that was  
used for authorizing a user (assuming it was successful, of course).  
For example, user Joe authenticated via PAP.
