this allows a ldb module to register a hook function called at various
stages of processing. It will be initially used for ldb command line
hooks, but should work generally.

this supports module loading in ldb which uses the approach of "load
all modules in a directory". This is much more flexible than the
current module loading, as it will allow us to load modules for
command line parsing and authentication.
Modules are loaded from a colon separated path, in the environment
variable LDB_MODULES_PATH. If unset, it defaults to LDB_MODULESDIR.
Within each directory modules are loaded recursively (traversing down
the directory tree). The device/inode number of each module is
remembered to prevent us loading a module twice.
Each module is checked for a ldb_init_module() function with
dlsym(). If found, it is called with the ldb module version as an
argument.
This control is exactly thought for the actions which previously were performed
using the RELAX one.
We agreed that the RELAX control will only remain for interactions with OpenLDAP.
these will be used to determine if a ldb request comes from an
untrusted source. We want requests over ldap:// to be marked untrusted
so we can reject unregistered controls

This must be available to the OpenLDAP backend, to set the GUID values
in some situations. We need a proper ACL mechanism to control the use
or abuse of this control.
This reverts commit 10adee89367cee9add993869280542418fb3d370.
This makes our LDAP much more secure and less error-prone.

this function takes the operator being invoked, which will allow
schema functions to provide more fine grained control over
comparisons.
The key bug this was introduced to fix is the incorrect handling of
the LDB_OP_PRESENT test for deleted linked attributes. The backends
are unaware of the deleted state of these links, so they cannot do a
LDB_OP_PRESENT test on their own.

It is the same as ldb_request_add_control, except it will replace
an existing control.

this is used to help debug async ldb requests. The ldb request handle
now contains a location string and the parent request pointer. This
allows us to print a backtrace of ldb requests in the dsdb modules.
When this flag is set on an element in an add/modify request then the
normal validate_ldb() call that checks the element against schema
constraints is disabled
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
This ensures that internal bits for the element flags in add/modify
requests are not set via the ldb API
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
The flags field of message elements is part of a set of flags. We had
LDB_FLAG_MOD_MASK for extracting the type, but it was only rarely
being used (only 1 call used it correctly). This adds
LDB_FLAG_MOD_MASK() to make it more obvious what is going on.
This will allow us to use some of the other flags bits for internal
markers on elements

this control adds a unique msDS-SecondaryKrbTgtNumber attribute to a
user object.
There is some 'interesting' interaction with the rangeLower and
rangeUpper attributes and this add. We don't implementat
rangeLower/rangeUpper yet, but when we do we'll need an override for
this control (or be careful about module ordering).

They are not quite safe to use (requires caller to steal
resulting message in own context) and may lead to holding
memory for too long.

Previos implementation from ldb_msg_canonicalize()
was moved into this function and now ldb_msg_canonicalize()
is based on ldb_msg_normalize()
Signed-off-by: Andrew Bartlett <abartlet@samba.org>
Old implementation from ldb_msg_diff() was moved into
this this function but with changed interface
so that a memory context may be passed.
ldb_msg_diff() function is now based on ldb_msg_difference(),
which fixes a hidden leak - internal ldb_msg object
(returned from ldb_msg_canonicalize) wasn't freed
and stays attached to ldb_context for the connection lifetime.

These will be used to help avoid the problem we have with hundreds of
places that do "return LDB_ERR_OPERATIONS_ERROR" without an
explanation. It is very difficult to track down ldb errors which don't
have any explanation.
By replacing "return LDB_ERR_OPERATIONS_ERROR;" with "return ldb_operr(ldb);"
we at least get a file:line message in the ldb error string. It isn't
an ideal error message, but it is much better than just "operations
error"
This change also makes ldb_oom() return the error code
(LDB_ERR_OPERATIONS_ERROR) so you can do:
return ldb_oom(ldb);
instead of:
ldb_oom(ldb);
return LDB_ERR_OPERATIONS_ERROR;
Check on modify if we are RODC and return referral.
On the ldap backend side now we pass context and ldb_modify_default_callback
to propagate the referral error to the client.
This changes the meaning of the ->prev pointer in our doubly linked
lists to point at the end of the list from the front of the list. That
allows us to implement DLIST_ADD_END() and related functions in O(1)
time, which can be a huge saving in many places in Samba.
This also means that the 'type' argument to various DLIST_*() macros
is no longer needed, but I have left it in for now to keep the
patchset small, which will make it easier to revert if any problems
are found. In the future we should remove the 'type' arguments.
(jra. Move the one use of DLIST_TAIL over to the new macros).
This control will allow inspection of internal ldb values, which would
normally be stripped before being presented to users. The first use
will be stripping linked attribute meta data extended components.
(as objectClass will always be a case insensitive ascii string, we can
make a much simpler match function here than for the general case).
