Thank you for the bug report and your patch.

An update FYI

Fixed by changing server as noted above.

Thanks for all the help @gniibe.

It should not be removed as I believe it is required to be compliant:

I'm afraid that your particular configuration would cause the problem of the negotiation.

Note that we now have also an option instead of the workaround from 2015

For various reasons dirmngr requires and implements a full resolver and implements that. This way all DNS queries are passed through Tor. Thus this is a feature and not a bug. The error message could be better but we can only return what SOCKS tells us.

Lot's of things changed in the meantime.

HKP keyservers are anyway out of fashion and thus we won't put anymore effort into his part of the code.

Lot's of changes since 2.4.

See for T6545 for a new request to support IDP.

I have now disabled the rewriting in the 2.4 branch. Those who want to keep the old behaviour may add

I will review the issue. A likely outcome will be to follow your suggestion but to add an option for the old behaviour to avoid further security discussions.

After diligently reading the code I realized that this bug has long been fixed. For reference here is the patch I wrote to extend dirmngr_ldap during my tests:

This has been solved loooong ago.

We need to extend dirmngr_ldap.c to take a list of attributes to return. We already have the --multi option which returns all attributes for latter filtering by the caller but the specified attr is also used and thus dirmngr's start_cacert_fetch_ldap() retruns only the requested caCertificate.

Hello All,

The code has meanwhile been reworked and the mentioned test server is not anymore available
