For background see these comments from gpgme:

/* The output for external keylistings in GnuPG is different from all
   the other key listings.  We catch this here with a special
   preprocessor that reformats the colon handler lines.  */
/* The format is:

   pub:<keyid>:<algo>:<keylen>:<creationdate>:<expirationdate>:<flags>

   as defined in 5.2. Machine Readable Indexes of the OpenPGP
   HTTP Keyserver Protocol (draft).  Modern versions of the SKS
   keyserver return the fingerprint instead of the keyid.  We
   detect this here and use the v4 fingerprint format to convert
   it to a key id.

   We want:
   pub:o<flags>:<keylen>:<algo>:<keyid>:<creatdate>:<expdate>::::::::
*/

Regarding the freeing of values: I was not able to find a
specification stating it is okay to pass NULL to ldap_value_free, thus
the new wrapper.  Also add robustness measures in case ldap_get_value
returns an empty array.

(cherry picked from commit 03f83bcda5)

Note that we keep on using the term "passphrase" although "password"
would be better.  There are however so many occurance of this and
given it is a bike shedding topic we fix that in the PO files.

dirmngr: LDAP search by a mailbox now ignores revoked keys.
* dirmngr/ks-engine-ldap.c (keyspec_to_ldap_filter): Ignore revoked
and disable keys in mail mode.
--

The LDAP schema has a revoked and a disabled flag.  The former will be
set if a revoked key is uploaded; the latter can be set by other
means.   With this change a search by mailbox does not anymore return
keys with these LDAP attributes set.  This allows to better maintain a
directory with multiple keys per mailbox.

Doing the same for expired keys could also be done but requires more
effort.

* scd/apdu.c (close_pcsc_reader): Do not decrement refcount if already

(apdu_dev_list_start): Unlock prior to close_pcsc_reader.  For PC/SC

* scd/apdu.c (pcsc_error_string): Add an error code.
* scd/scdaemon.c (scd_kick_the_loop): Fix a diagnostic.
--

There was an obvious bug in that the pcsc.count could go below zero
and thus there was no chance to get the context release.  Releasing
and recreating the context is at least under Windows important to get
rit of the PCSC_E_SERVICE_STOPPED.

Also removes a potential problem in holding the reader_table_lock
between calls to apdu_dev_list_start apdu_dev_list_finish.  There is
no need for this.  Instead we bump the pcsc.count.

The reader_table_lock strategy should be reviewed; we may be able to
remove it.

In contrast to a search via keyserver_import_ntds the older
keyserver_import_name used a full match of the provided name despite
that it is only called with an addr-spec (mbox).  Due to the mode the
pattern send to dirmngr was prefixed with a '=' and thus dirmngr used
an exact search;.  This did only work for provided user ids like
"foo@example.org" but not for "<foo@example.org>" or
"Foo <foo@xample.org>".  The old code dates back to 2010.

I can be assumed that configured LDAP servers are somehow curated and
