Authentication issue with SVN URL

I have a Windows XP source server hosting Collabnet Subversion server +
mod_auth_sspi (Windows domain authentication). mod_auth_sspi is configured
to give both my user account and admin account full read/write access to the
relevant repository. I am able to successfully perform all SVN commands
(actually TortoiseSVN commands) successfully under either my user or admin
account.

If I log into Windows with my user account, then attempt to use FireFox to
browse a SVN source URL (say the repository root URL
http://sourceserver/svn/src), I get two SSPI (Windows domain) challenges.
The first challenge is

Enter user name and password for "" at http://sourceserver/

This challenge accepts only my user account credentials, but rejects my
admin account credentials.

The second challenge is

Enter user name and password for "Anseri Source Server" at
http://sourceserver/

This challenge accepts either my user or admin credentials.

The second challenge I recognize, it identifies the server as "Anseri Source
Server", the way I configured it, and accepts the credentials I authorized
for source server access.

I have no problems browsing when I use IE, but I suspect this is because IE
is caching my credentials while Firefox is not. I would bet that IE is
answering two challenges as well from cache.

How do I figure out where the first challenge is coming from? Could it be
Collabnet SVN Server's HTTP server? How do I verify this?
