I bumped into some issues for a client/server project that tried to perform its own SSPI/NTLM base64 authentication on the server side.
Some links that helped me debug that combo:
- NTLM Authentication Scheme for HTTP.
- [MS-NTHT]: NTLM Over HTTP Protocol: 4.1 Server Examples.
- [MS-NTHT]: NTLM Over HTTP Protocol: 4.2 Proxy Examples.
- Killing Mind: NTLM Message Decoder.
(c code with binary for Mac OS X) - HttpClient – NTLM support in HttpClient.
- NTLM.
- aurora-project’s NtlmAuthenticator.java.
