I have created a bdc model using .net custom connector which connects to the External system via a custom built webservice. It works when I open the external lists locally from the SharePoint server but I get the famous 'The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'NTLM'. error when I try to open the external list on a client computer.
Tried changing the clientauthenticationtype in the httpBinding to Windows or Ntlm and also manipulated the authentication providers of the webservices in IIS but that didn't work.
Hope someone can help me.
