Created this script based on the existing ms_schema.py script.
- Removed some unnecessary transformations that are only necessary for schema
processing.
- Added capability to parse and properly output base64-encoded values.
- Removed unnecessary attributes based on what attributes were present (and also
what were explicitly removed) from display_specifiers.ldif.
This is a perl script that does TSIG-GSS DNS updates against a AD
DC. The bind 9.5 nsupdate still doesn't seem to work with TSIG-GSS,
and we need a way to do DNS updates when we vampire a domain, so I
revived this ancient perl script and added a wrapper script that can
update DNS entries using our machine account credentials
The version of the unitest python module in Ubuntu Jaunty doesn't seem
to support this many level of subdirectories. Moving the tests up one
level solves the problem.
The previous patches to the provision system cut down on the number of
reconnects, and disabled the partition handling for part of the
process. This means we lost the setting of @OPTIONS as a replicated
attribute into the partitions.
Andrew Bartlett
This allows us to test out the code that will do the modify of the
prefixMap, and to provide the bindings that may assist a future
upgrade script.

- Centralise the lookups for the default domain (root) in the call "domain_dn"
- Reduce the LDB connections attempts ("connect" calls) from three to one
- tools should load faster
- Make the LDB connection init more like the "ldb_wrap_connection" call
- Load the right UTF8 casefolder which fixes up problems with special characters
(discovered by me: e.g. small "Umlaute" (ä, ö, ü, ...) in the DN weren't upcased
- so records "seemed" lost in TDB)
This reverts commit 53ef426e6f.
As abartlet pointed out this causes to load all attributes and therefore gives
us more here than we need (only the check for the DN)!
Andrew, can you please check this? The idmap.setup_name_mapping tests
look totally out of place here. I'm also not sure I captured your
intention with the other changes
The Samba4 schema code (called via
samdb.set_schema_from_ldb(schema.ldb)) manages the @ATTRIBUTES and
@INDEXLIST records, so don't wipe them early. The chances are that we
will not change them anyway.
Andrew Bartlett
This fixes the recursive delete in erase_partitions()
For reasons I cannot understand, it is possible to get 'no such
object' trying to delete a DN I just search for without error. Oh
well...
Andrew Bartlett
Using a single transaction to both erase the bulk of the data and the
rebuild of that data means that the in-memory index list is
maintained, and not written out to disk until it is all compleated.
All the writes then occour at the end.
Andrew Bartlett
This removes a *lot* of duplicated code and the cause of much
administrator frustration. We now handle starting and stopping the
slapd (at least for the provision), and ensure that there is only one
'right' way to configure the OpenLDAP and Fedora DS backend
We now run OpenLDAP in 'cn=config' mode for online configuration.
To test what was the provision-backend code, a new --ldap-dryrun-mode
option has been added to provision. It quits the provision just
before it would start the LDAP binaries
Andrew Bartlett
This makes it possible to do a bit more of the provision with Samba
helpers, but without some of the otherwise useful things (such as
loading in the global schema) that SamDB does.
Rewrite provision_erase to use a recursive search, rather than a
looping subtree search. This is much more efficient, particularly now
we have one-level indexes enabled.
Delete the @INDEX and similar records *after* deleting all other
visible records, this hopefully also assists performance.
Andrew Bartlett
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.
Adnrew Bartlett
Tests for the right behaviour of this introduced constructed attribute.
Since we don't support the read-only-ness of those attributes yet, I commented
some lines out.
Also I had to add a function for python which converts domain SIDs in RIDs.
And a small fix for the "groupType" test.
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.

Andrew Bartlett
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.
Andrew Bartlett
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 ....
This script walks the schema, configuration and domain partitions of the locally
installed Ldb and a remote hosts and compares the descriptors disregarding the
difference in domain SID. The goal is to make sure a freshly provisioned Samba
has the correct descriptors so ACLs work correctly. It outputs the descriptors
in short SDDL, where the correct SIDs are to be replaced during provisioning.
Optionally it can be output as an LDIF file with the current local domain and
domain SIDs.
The conversion from EJS to python I did with Jelmer this morning was
not quite complete, due mostly to the difference between print in EJS
and python (python implies a newline).
Andrew Bartlett
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.

- removed workaround for olcSyncprovConfig - creation (works perfect now
with 2.4.15, release was today)
- added 1 message-helpline, which is displayed when running
provision-backend with olc and/or mmr setup
- corrected 1 wrong slapcommand-helpline
- slapd.conf is removed now in case of olc-setup
- added 1 copyright-line to provision.py and provision-backend
Signed-off-by: Andrew Bartlett <abartlet@samba.org>
These extensions add mmr (multi-master-replication) and olc
(openldap-online-configuration) capabilities to the
provisioning-scripts (provision-backend and provision.py), for use
with the openldap-backend (only versions >=2.4.15!).
Changes / additions made to the provision-backend -script:
added new command-line-options:
--ol-mmr-urls=<list of whitespace separated ldap-urls> for use with mmr
(can be combined with --ol-olc=yes),
--ol-olc=[yes/no] (activate automatic conversion from static slapd.conf
to olc),
--ol-slaptest=<path to slaptest binary> (needed in conjunction with
--ol-olc=yes)
Changes / additions made to the provision.py -script: added
extensions, that will automatically generate the chosen mmr and/or olc
setup for the openldap backend, according to the to chosen parameters
set in the provision-backend script

We need to avoid handling DN+Binary and DN+String with the refint
module for now, as this is a currently unsupported syntax.
Also rename entryTTL to avoid a conflict with the operational
attribute of the same name.
Andrew Bartlett
We didn't handle the mode where we can't load the main sam.ldb due to
the modules being 'wrong', and when we did remove the file, we didn't
wipe the partitions.
