We have a scenario where we are trying to send SOAP message over receiver SOAP adapter using Basic Authentication to MuleSoft service. Now we have 32 characters of UserID and 32 characters of Password. When I am using SOAP UI with "Authenticate pre-emptively", I can see below HTTP Authentication Header in the Request and receive successful Response:
Authorization: Basic NTA1YzAyMjk4ZTA4NGZlNGI1ODk1YjBjN2Y5YWQxMmM6YzJmNDk0NDQ1ZDhlNGQ3MkFBMjM3RTA1NTYxMUE5RDI=
But when we are sending through receiver SOAP adapter, HTTP Authentication Header is getting truncated and receiving "invalid_client: wrong client_id or client_secret" error. At MuleSoft server, we can see last few characters are truncated from Password.
I am not sure whether PI has any Character limitation for HTTP Authentication header. Please provide your suggestion.
