[squid-users] Squid + Samba + AD "Cache Access Denied"

I have Squid set up to auth proxy usage via AD.

If I go to my webmail site (with Firefox) which runs off port 2095 on Horde I get:

----------------------------

ERROR
Cache Access Denied
 
While trying to retrieve the URL: http://www.zigzagsoft.com:2095/
The following error was encountered:
· Cache Access Denied.
Sorry, you are not currently allowed to request:
    http://www.zigzagsoft.com:2095/
from this cache until you have authenticated yourself.
You need to use Netscape version 2.0 or greater, or Microsoft Internet Explorer 3.0, or an HTTP/1.1 compliant browser for this to work. Please contact the cache administrator if you have difficulties authenticating yourself or change your default password.

If I hit REFRESH in the browser, I get straight in. So, it doesn't appear to be a misconfiguration.

Any clues?
