Proxy settings in SVN

Hello all,
                It's my first time posting to this list and I am not subscribed so please CC me on any replies.

                I'm having difficulty with the proxy settings in Windows version of svn (I'm using the WANdisco compiled version). It seems as though no matter what I put in the appdata\roaming\subversion\servers file the settings are ignored and the svn is defaulting to the windows control panel settings. This would be fine but we utilize a proxy.pac autoconfigure and require proxy authentication. Between those two settings for whatever reason svn seems to be unable to deal with the proxy's request for authentication. I've tcpdumped the connection information from the proxy itself and it looks like svn just isn't answering.

The basic gist of the stream goes like this:
Source Dest Protocol Length Message
clientIP proxyIP HTTP 121 CONNECT www.svnrepository.tld:443 HTTP/1.1
proxyIP clientIP HTTP 236 HTTP/1.1 407 authenticationrequired (text/html)
clientIP proxyIP HTTP 217 CONNECT www.svnrepository.tld:443 HTTP/1.1 , NTLMSSP_NEGOTIATE
proxyIP clientIP HTTP 252 HTTP/1.1 407 authenticationrequired , NTLMSSP_CHALLENGE (text/html)

And then silence. The app correctly interprets the first 407 and tries connecting again but this time with an NTLMSSP_NEGOTIATE but when the proxy comes back with a CHALLENGE svn never responds with credentials. I worked with my proxy vendor and we tried to find ways around it but short of turning off authentication they are chalking it up to a bug in the HTTP client implementation. Any help would be much appreciated.
