Many sites use an internal LDAP directory to distribute keys. However, external sites do not have access to this resource and thus a way to distribute the same keys via WKD should exists. To make deployment easy a cronjob should pull keys from the internal LDAP and an prepare them for upload to the WKD.

Required tasks:

• Extend dirmngr to get all keys from the LDAP
• Extend gpg-wks-client to take key from dirmngr.
• Add a way to filter by domains and via a blacklist
