Problem with NTLM on windows

Hello,

after upgrading libCurl in our application from 7.21.2 to 7.22.0 we encountered
the following problem:
Our server-application does lots of outgoing http-connections to different hosts
via the multi-interface. We used to compile libcul with the USE_WINDOWS_SSPI
macro (we used that for NTLM-proxy-authentication on the client side). It seems
that some of the NTLM changes in libCurl triggered a serious memory leak in
the windows-service lsass.exe.
After rebuilding libCurl without the USE_WINDOWS_SSPI macro, as we don't need
NTLM on the server side, the problem went away.

Has anybody else saw that problem? Is this a problem on libcurl or in windows
(I suppose it's a windows problem triggered by something in libcurl).

Regards,

Christian
