Timestamp server authentication issues

Question

I'm using Adobe Reader XI and when using http timeStamp server that requires basic authentication is always tried without the needed BasicAuth field set.
That's the request adobe send
POST /cdie/HttpService HTTP/1.1
accept: */*
content-type: application/timestamp-query
content-length: 69
character-encoding: binary
user-agent: PPKHandler
connection: Keep-Alive
cache-control: no-cache
The reply is a simply HTTP/1.1 401 Unauthorized because the request hasn't the authentication field.
I've tried using Windows and Macintosh
Why didn't send the basic authentication?

Answer 1

What exactly are you trying to do? Are you signing a PDF with a certificate-based digital signature? You cannot sign in Adobe Reader unless your PDF is Reader-extended with permissions to sign.
If your PDF is Reader-extended or you're signing with Acrobat Pro, and you want your signature to be timestamped you need to set up the timestamp server in Acrobat/Reader. If your timestamp server requires authentication, you need to provide authentication information in the Acrobat's timestamp server setup. Some signing credentials (Digital IDs) have timestamp server information embedded in the certificate. In this case Acrobat will use this timestamp server to timestamp the signature and you do not need to set up this timestamp in Acrobat's timestamp servers list unless this timestamp server requires authentication. If it requires authentication, you need to set it up in Acrobat/Reader providing authentication info.
You should never access timestamp server if you just open a signed PDF.
