The idea here is to unify our use of URLS or colon delimited ldap
keyserver specification. The requirement for percent escaping, for
example the bindname in an URLs, is cumbersome and prone to errors.
This we allow our classic colon delimited format as an alternative.
That format makes it also easy to specify flags to tell dirmngr
whether to use starttls or ldap-over-tls. The code is nearly 100%
compatible to existing specification. There is one ambiguity if the
hostname for CRL/X509 searches is just "ldap"; this can be solved by
prefixing it with "ldap:" (already implemented in gpgsm).

detect this here and use the v4 fingerprint format to convert
it to a key id.

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.

* dirmngr/ks-engine-ldap.c (keyspec_to_ldap_filter): Ignore revoked

--
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.

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

Note that "gpgNtds" is per RFC-4512 case insensitive and has not yet
been officially regisetered. Thus for correctness the OID can be
used:

1.3.6.1.4.1.11591.2.5.1 gpgNtds=1 (auth. with current user)

authentication and are resevered for future use.

* dirmngr/ks-engine-ldap.c: Wrap some ldap calls.
--
The former gpgkeys_ldap module has once been ported to dirmngr but
unfortunately the dirmngr_ldap wrapper has not been used so that we
have internal LDAP calls with these problems:
- No usable timeouts.
- On non-Windows platforms a lot of extra libs and possibly even a
second copy of Libgcrypt is pulled in.
- Only one threads runs at a time.
This patch mitigates the last point.

This is a first take on better Active Directory support. The main

* dirmngr/ks-engine-ldap.c (extract_attributes): Do not store the

* g10/call-dirmngr.c (ks_put_inq_cb): Do not emit sig records.

The pgpSignerID has no use in the LDAP and thus don't store it.
David's idea back in 2004 was
/* This bit is really for the benefit of people who
store their keys in LDAP servers. It makes it easy
to do queries for things like "all keys signed by
Isabella". */
See-commit: 3ddd4410ae
I consider this dangerous because such a query is not able to validate
the signature, does not get revocation signatures, and also has no
information about the validity of the signatures. Further many keys
are spammed tehse days with faked signatures and it does not make
sense to blow up the LDAP with such garbage.
