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


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


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?
