Fields for entering user/password in Timestamp Server configuration dialog disabled

Hi there,

we would like to use a time stamping service that requires authentication. Unfortunately the input fields in the corresponding UI are disabled. I managed to set the "is required" flag by setting the bAuthRequired Flag in the registry, but I did not manage to set the required credentials. sPassword and sUser suggest that they are the correct places in the registry, it won't work.

On a system where the Acrobat Reader has not been customized the UI is enabled and I can add user/password and the registry contains a value for tLockboxId, which references a secure place where the credentials are stored. I was not able to set this up by myself in the customized system.

Any help is highly appreciated.

Thanks, Anna

So in case anyone else is experiences this, it turned out that if the following registry key is set to "0" then the dialog is disabled:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown\cSecurity\cPPKLite\bAllowPasswordSaving

Anyone else with an idea why a system would behave like mine does?

Or an idea how to make Acrobat Reader use the credentials I have for my time stamp service?

So explain how you want this to work.  Does the user press a button on a PDF form to get the timestamp?  Can you configure and install something all the system of all the users that need this?

Hi @Thom_Parker,

we use the "Certificates" tool to sign PDFs digitally. For this purpose we configure a time stamp server under Edit -> Preferences -> Signatures -> Configure Time Stamp Server Settings -> New

This will bring up this dialog here with the disabled log on options:

I was able to "tick" the "This server requires me to log on" option by modifying the registry entry Computer\HKEY_USERS\S-1-5-21-1068617757-682864690-1294233929-4888\Software\Adobe\Acrobat Reader\DC\Security\cPPKHandler\cTimeStampServers\c0\bAuthRequired - but I did not manage to make the Acrobat Reader use the provided username and password I have for my time stamping service.

Any ideas?

Anna
