This is a first take on better Active Directory support. The main
change for NTDS in the code is that the an top-RDN of CN is used
instead of the old pgpCertID. More changes to come; for example using
and storing the fingerprint.

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

The code used the wrong list which resulting in adding attributes

such an data and rejects them. The bug was introduced into 2.1 while
porting the code from the old keyserver helpers to dirmngr.

this to allow Unicode directory names. There is also one case where
files are written using the old fopen. The new option parser in 2.3
does not have this problem but at some places fopen is also still used.

Yes, I know that there is a lot of code duplication. In fact some of

directly extract into an unsigned int or char *.

This is a pretty stupid fix but one which works without much risk of

the fallback to other host would have been too limited. With the used

TRIES is still cumulative and not per host.

The old algorithm limited the length of a bucket chain by purging the

cache were never purged. The new algorithm is a bit better: It also
limits the chain length on overflow to 50% but tries to keep the
entries indicating that a WKD is available in the cache. If there is
still space to keep more, those which clearly do not support WKD are
also kept.
