Re: Garbled class attribute?

I have a bunch of users which should have a class attribute returned upon 
successful authentication.  Their entries look something like:
bob       NAS-IP-Address == 172.31.33.66, Hint==HasSlash Auth-Type:=Accept
           Class = "OU=MY_CORP", Filter-Id = "SPCCOLO_O", 
Split-Tunneling-Policy = 1, Split-Tunnel-List = "SPCCOLO_ST"
What they're actually getting back is:
Packet-Type = Access-Accept
User-Name = "bob"
Class = 0x3739774831423272375053516a71424143444358434979507544493d
Which is '79...'
*nod*.
...
It works for me, so my guess is that something else in your
configuration is setting Class to that value.
Okay, I'll bite - so what on earth might be causing that?  I'm not doing any 
rewriting, and both the Filter-Id and the Split-Tunnel-List attributes come 
back as strings.  I thought maybe it was getting confused on the Class since 
it contains an =, but changing that to an _ doesn't help.  Is this perhaps 
coming back from the proxy server, and if so, is there a way to use my local 
Class attribute instead?

My users file has a whole bunch of entries that look like the above, mostly like:

  bob       NAS-IP-Address == 172.31.33.66, Hint==HasSlash, Proxy-To-Realm:=UAS
            Class = "OU=MY_CORP", Filter-Id = "SPCCOLO_O", 
Split-Tunneling-Policy = 1, Split-Tunnel-List = "SPCCOLO_ST"

My hints file looks like:

DEFAULT         User-Password =~ ".*/.*"
                 Hint = HasSlash

My proxy.conf looks like:

proxy server {
         synchronous = no
         retry_delay = 5
         retry_count = 1
         dead_time = 300
         default_fallback = yes
         post_proxy_authorize = yes
}
realm UAS {
         type            = radius
         authhost        = radius.domain.com:1812
         secret          = MySecretKey
}

And my radiusd.conf looks uninterestingly like the following (note that the 
syslog sections are part of rlm_syslog which I submitted a while back):
