A client has trouble logging into our webpart (SP 2007). Apparently, his internet connection is via a proxy server. He has no problem logging in to our main website. Authentication from both the webpart and the website is through the same API.

Any suggestions? Thanks.

I think the proxy server is the prob. Browser authentication over proxy is not supported when using NTLM.

Sharepoint uses NTLM or Kerberos authentication.
