Thanks for your reply. But unfortunately I haven't found an easy way to make NTLM work, as single-sign-on application in a windows domain. Just for information, how we solved it finally: With a hint from a colleague we used the THTTPClient-component from System.Net.HttpClient, which supports NTLM and also the newer Negogiate-protocol from windows, as we need it for our application. So with this component we have to create some code to process the JSON data, but the heavier part with security, sign-on and TLS comes right out of the box from Delphi.

Hello, i'm trying to get a simple REST request working with NTLM authenticaion and "single sign on". I'm working with the OverbyteIcsHttpRestTst sample and the TSslHttpRest component. When i use NTLM as authentication i get the http-response 401 and automatically the Login-Form pops up and after entering my username and password i get the correct response (200). But after searching and debugging the source-files for HttpProt, NtlmSsp, ... i didn't find or see the correct configuration properties to get it working without entering my credentials. I tested the HttpRest1.LmCompatLevel := 1; right before doing the RestRequest but it doesn't change anything. But i don't see how single sign own should work as mentioned in change V8.61 Can some give me please some hints we to look for the correct propreties, config or procedure to get it running. Thanks for your help in advance Regards Stephan
