Adobe reader timestamp problem

[nemanja1209]

Adobe reader can't timestamp document.

Server returns: Rejection.

Reason: There is no Authorization field in the HTTP Basic auth request.

I have tried the same thing with JSignPDF and it works perfectly.

In Adobe Reader I have set my timestamp server under Preferences > Security and my credentials also.

The timestamp server is hosted on the Linux machine.

Here are 2 screens. First one Adobe Reader, second one JSignPDF

I'm having the exact same issue. Any ideia why Acrobat doesn't send the Authorization Header?

I have own time stamp server and have same problem.

My latest version of Acrobat Reader DC (2020.012.20048) still have this problem.

Do we have a solution for this problem?

My temporary workaround:

1 setup time stamp server URL in Acrobat Reader DC to a time stamp proxy server URL
(no need to add username and password because it is broken)

2 timestamp proxy server receive time stamp request from Acrobat Reader DC then it will
add http basic authentication into http header request and then forward the modified http request to time stamp server.

3 time stamp server will receive time stamp request and http basic authentication as required

4 time stamp server reply back the time stamp response to time stamp proxy server.

5 time stamp proxy server forward the time stamp response back to Acrobat Reader DC.

6 done.

The diagram will look like:

Acrobat Reader DC <-------> time stamp proxy server <------> time stamp server

You can implement you own time stamp proxy server with any http client/server library.

I use golang with fasthttp library. it provide me both client and server http library.

It work very well in my use case.

Thanks to xnetbug!

It works now.
"Acrobat Reader only sends the credentials after the server replies with a 401 Unauthorized and includes a "WWW-Authenticate", "Basic realm=something"  Header. It worked for me. "
