Seems something went wrong (local error) when setting up an LDAP server for key storage. So after configuring something like (`.gnupg/gpg.conf`)
```
keyserver ldap://ldap-server/????bindname=uid=LordPrivySeal%2Cou=GnuPG%20Users%2Cdc=example%2Cdc=com,password=secret
```
(this is single line, of couse)
... and publishing a particular key, I receive an error:
```
gpg --send-keys 6AD74D237F2EEA93271474C20840333D9F15A045
gpg: sending key 0840333D9F15A045 to ldap://ldap-server.demo.gnupg.com/????bindname=uid=LordPrivySeal%2Cou=GnuPG%20Users%2Cdc=example%2Cdc=com,password=secret
gpg: keyserver send failed: Invalid LDAP credentials
gpg: keyserver send failed: Invalid LDAP credentials
```
The actual problem: That password (`secret`) should not be shown in any error message unless required by the user. The current situation allows credential stealing by a watcher.
Observed with gnupg 2.2.27 and kleopatra 20.08.3 (which echos the gpg error message).
