This allows us to load the schema against one ldb context, but apply
it to another. This will be useful in the provision script, as we
need the schema before we start the LDAP server backend.

As the version of OpenLDAP required for Samba4 is fairly new, we don't
want to make it a requirement before this python code is run in 'make
test'.
As such, skip over the actual starting of slapd, but check the rest
runs alright (which still validates syntax and other modules).
Andrew Bartlett
heres the summary of all changes/extensions:
- Andrew Bartlett's patch to generate indext
- Howard Chu's idea to use nosync on the DB included, but made optional
- slaptest-path is not needed any more (slapd -Ttest is used instead)
and is therefore removed. slapd-path is now recommended when
openldap-backend is chosen.
its also used for olc-conversion
- slapd-detection is now always done by ldapsearch (ldb module),
looking anonymous for objectClass: OpenLDAProotDSE via our ldapi_uri.
- if ldapsearch was not successfull, (no slapd listening on our socket)
slapd is
started via special generated slapdcommand_prov (ldapi_uri only)
- slapd-"provision-process" startup is done via pythons subprocess.
- the slapd-provision-pid is stored under paths.ldapdir/slapd_provision_pid.
- after provision-backend is finished:
--- slapd.pid is compared with our stored slapd_provision_pid.
if the are unique, slapd.pid will be read out, and the
slapd "provison"-process will be shut down.
--- proper slapd-shutdown is verified again with ldb-search -> ldapi_uri
-> rootDSE.
--- if the pids are different or one of the pid-files is missing, slapd
will not be shut down,
instead an error message is displayed to locate slapd manually
--- extended help-messages (relevant to slapd) are always displayed,
e.g. the commandline with which slapd has to be started when everythings
finished
(slapd-commandline is stored under paths.ldapdir/slapd_command_file.txt))
- upgraded the content of the mini-howto (howto-ol-backend-s4.txt)
We were missing the 'cn' attribute, which we then prepare a sorted
list based on. On Linux, strcmp(NULL, NULL) does not segfault, where
it does on FreeBSD.

Rather than have the functional levels scattered in 4 different,
unconnected locations, the provision script now sets it, and the
rootdse module maintains it's copy only as a cached view onto the
original values.
We also use the functional level to determine if we should store AES
Kerberos keys.

The LDB_ERR_NO_SUCH_OBJECT varient is not a defined variable. This
should improve error handling in our python code on some
systems. Unfortunately it still doesn't work on mine. I need to trap
Jelmer somewhere where he can't escape some day and force him to
divulge the deep druid secrets of python exception handling ....
I've patched the new ms_schema.py (which was intended to be used as a
library) to function as minschema_wspp if invoked standalone. Although
this is less robust than minschema_wspp on incorrect data, having two
programs doing the same thing might not be good idea.

This removes a level of indirection via external binaries in the
provision-backend code, and also makes better use of our internal code
for loading schema from an LDIF file.
Remaining to do: Sort the output again, as the load from LDIF is
unsorted (also needed because the normal LDB load from sorted input is too slow
anyway, and is only needed here).
Andrew Bartlett
For example, if we don't create the admin user (perhaps expecting
users to be in LDAP already, or we are due an incoming replication) we
should not confuse the administrator by printing a unused password.
Andrew Bartlett
Here's a first attempt at moving the minschema_wspp code into a
library as Andrew requested. Since this script no longer has to
generate CN=aggregate, I've simplified it quite a bit to a level where
it almost does a line-by-line translation. This is faster and simpler,
but it may not catch as many errors in the ad-schema files as the
previous versions did.
