ACL CHANGES:
by <who> <access> changed to by <who>+ <access> (joined with AND)
added peername=<regex> sockname=<regex> url=<regex>
removed addr=<regex> (use peername instead).
replace dn_upcase with str2upper and str2lower. Use where needed.
Partial support for a new option to help debug TLS connections,
not yet user-settable. Defaults "on" for now.
Partial support for temporary RSA keys, skeleton for DH.
Add call to X509V3_add_standard_extensions() on init, mod_ssl
does this too, but I am unsure about what it does.
Move management of client CA certificates to a new routine, since
it is going to get more complex than the current code.
Some content for tls_verify_cb where parts of our policy should
be implemented.
The rest of this change mostly contains random ideas taken from
mod_ssl. The purpose is to get the repository in sync with the
code I am testing. I still can't manage to make Netscape send
its certificate to slapd, though it works with Apache/mod_ssl
(with the same certificates). Trying s_client against both
does not shed any light. If anyone manages to make it work,
please let us know.
Move the input data exhaustion loop to connection.c from daemon.c
Let transport (TLS or somesuch) force reading or writing on
sockets even if the higher layers think otherwise.

Namespace changes
added slap_ and ldbm_ to many structures
added typedefs to many structures
used typedefs
New main.c argument parsing with ldap url support (replacing -a address).
New sockaddr_in handling and support for multiple listeners.

Import patches mistakenly applied to OPENLDAP_DEVEL_REFERRALS.
ldap_modify: delete of last attribute value should delete attribute (ITS#229)
thr_nt: use sleep to yield
Look on connection_read() if it returns positive so it has a chance
to exhaust all protocol units received from the transport layer.
I think this is the necessary fix for the TLS-data-ready/
socket-not-ready issue, but I have not experimented that problem
yet, so I am unsure about its effectiveness.
Now, do we need something like that for connection_write? How would
we go about implementing it?
Move calls to ldap_pvt_tls_accept to connection_read instead of
connection_init so that we get into the select() logic.
Make use of new flags in the connection.
BTW, and before I forget, it sort of works. I have connected with
a Netscape client using a secure connection and did a failed
search (my test database is empty), but the trace looked correct.
Make sure you have your CA certificate in your Netscape preinstalled.
Otherwise, the connection fails with error 0xFFFFFFFF that is rather
uninformative.
Two new flags in Connection. One to indicate that it is a raw TLS
section (that is, not SASL). The second to indicate that we need to
do SSL_accept on this connection.
Definitely, 'dn' and 'distinguishedName' are different things. The
former is a pseudo attribute type used internally by slapd to represent
the distinguished name of an entry and its existance should not be
visible. The latter is an "abstract" attribute type that is not meant
to exist in practice except as supertype of other dn-valued types.
So, the definition of attribute type 2.5.4.49 has been changed to be
just distinguishedName. Work on the OPENLDAP_DEVEL_SCHEMA branch will
treat pseudo attributes especially and will not be visible to the
clients.

Import experimental referral implementation from OPENLDAP_DEVEL_REFERRALS.
Includes support for update referral for each replicated backend.
Reworked replication test to use update referral.
Includes major rewrite of response encoding codes (result.c).
Includes reworked alias support and eliminates old suffix alias codes
(can be emulated using named alias).
Includes (untested) support for the Manage DSA IT control.
Works in LDAPv2 world. Still testing in LDAPv3 world.
Added default referral (test009) test.
Set ciphers from slapd.conf.
More error checking and reporting.
Slowly getting there, SSL_accept succeeds now, but connection breaks
immediately after that (my glue logic with slapd is broken).
A couple of options for TLS configuration. Still a conflict here,
the default context is initialized before the config file is read,
so the locations are not know at context initialization.
New routine tls_report_error to analyze errors from OpenSSL
Change temporarily the default protocol from TLSv1 to SSLv3 with
fallback to SSLv2. This seems necessary for slapd to accept connections
from Netscape.
Try to set the cipher list in the default context. Does not semm to
work yet.
Parsing of flag -T was falling through to the default case.
Init the TLS environment if necessary. Lots of things needed here,
in particular, preparing properly the default context.
Our check for SSLeay_add_ssl_algorithms fails with modern versions of
OpenSSL since it has been made a preprocessor macro. Please review
this change to do the right thing w.r.t. rsaref.
