Hello,

I am trying to execute a Http Callout to a webservice that is with windows machine and the credentials were given to me as domain\username

password

I wrote a simple http callout as mentioned in the docs. Did the base 64 thing for username:pwd but I keep getting

HttpResponse[Status=Unauthorized, StatusCode=401]

I tried to put domain as domain\username, domain:username:password with other combinations of moving domain first and last but nothing seems to work.

I have my authorizationheader set as follows

    Blob headerValue = Blob.valueOf(username + ':' + password);
    String authorizationHeader = 'NTLM ' +   EncodingUtil.base64Encode(headerValue);

I tried BASIC above and then tried NTLM too but with same result.

Any help is greatly appreciated.

Thanks
