NTLM auth for web services

[Dhruva Ray]

Hi,

We have secured our web service using NTLM authentication.
However, we are facing problems while trying to
authenticate using the .NET CF libraries on the Pocket PC.
For e.g. the code below:

System.Net.NetworkCredential cred=new
System.Net.NetworkCredential(username,passwword,domain);

This works only when the web server has basic
authentication set. How does one make it work for NTLM?

Any help in this respect will be highly appreciated.

Regards,
Dhruva Ray

NTLM authentication is not supported by the Pocket PC platform.

That does not sound correct for 2 reasons:

*Pocket IE supports NTLM authentication in PPC 2003
*THe Pocket PC SDK 2003 mentions support for NTLM SSPI

Can you please clarify?

Thanks
Dhruva Ray

Sorry, I meant to say that the System.Net bits
(HttpWebRequest\Response, Web Services etc...) in the
Compact Framework currently don't support NTLM
authentication.

Thanks! Is it possible to acheive the same through
p/invoke? Any pointers?

Using Digest authentication instead of Basic or NTLM authentication is the
recommended solution. Digest authenticatioin is supported on the .NET
Compact Framework.
