Hello,
recently I've upgraded my KDE from KDE-3.4 to 3.5.4 (compiled from source).
After updating I wasn't able to browse website with konqueror any more. The
proxy server rejected all of my requests. But I was still able to use firefox
for browsing.
Our proxy server uses NTLM for authentication.
When I pulled some tcpdumps I realized two differences between firefox and
konqueror:
1) firefow always fills both, the NTLM response and the LanManager response,
with the same key in the NTLMSSP_AUTH packet. konqueror only fills the NTLM
response.
2) konqueror doesn't send any flags in the NTLMSSP_AUTH packet. firefox does.
So I change the kntlm.cpp file a bit:
--- kntlm.cpp.orig 2006-09-26 13:05:06.000000000 +0200
+++ kntlm.cpp 2006-09-26 13:06:11.000000000 +0200
@@ -160,14 +160,14 @@ bool KNTLM::getAuth( QByteArray &auth, c
if ( KFromToLittleEndian(ch->flags) & Negotiate_NTLM ) {
response = getNTLMResponse( password, ch->challengeData );

} else {
if ( !forceNTLM ) {
response = getLMResponse( password, ch->challengeData );

} else
return false;
}
+ addBuf( rbuf, ((Auth*) rbuf.data())->ntResponse, response );
+ addBuf( rbuf, ((Auth*) rbuf.data())->lmResponse, response );
// }
if ( !dom.isEmpty() )
addString( rbuf, ((Auth*) rbuf.data())->domain, dom, unicode );
With this patch applied I'm now able to use konqueror to browse through the
NTLM-proxy.
Can anybody with deeper insight please review this patch, and commit it if ok.
Cheers, Robert
