This simplifies the code considerably. A real attempt at an LDAP backend would need to implement this
module in a similar way to LDB.

This feature has long been obsolete, remaining only in the hope
that it might be revived in the future.
Specifically, in 2011 the S4 OpenLDAP backend HOWTO was removed:
commit 1d46325af8541ea467c79cd86e65f93ce6a14ff4
Author: Andrew Bartlett <abartlet@samba.org>
Date: Wed Apr 27 22:42:29 2011 +1000
Remove outdated S4 OpenLDAP backend HOWTO.
There is a project to revive this, hosted here:
https://github.com/Symas/samba
and
https://github.com/Symas/samba_overlays
However discussions at SambaXP with Nadezhda Ivanova
indicate a new approach with slapd being started by Samba
and taught to read native Samba ldb files is more likely
in the short term.
This has the advantage that Samba's provision and offline
tooling would not need to change, with the solution looking
more like how BIND9_DLZ has access to the Samba DB.
If any of this is required then reverting these patches will be
the least of the difficulties in bringing this to production.

EnumDomainUsers currently takes too long, significantly slowing down
calls to winbind's getpwent which is a core unix API. The time is taken
up by a GUID lookup for every record in the cached result. The advantages
of this approach are:
1. It meets the specified requirement that if a record yet to be returned
by a search in progress (with a resume handle) is deleted or
modified, the future returned results correctly reflect the
new changes.
2. Memory footprint for a search in progress is only 16 bytes per record.
But, those benefits are not worth the significant performance hit
of the lookups, so this patch changes the function to run the search
and cache the RIDs and names of all records matching the search when
the request is made. This makes the memory footprint around 200 bytes
per record or up to 2MB per concurrent search for a 100k user database.
The speedup achieved by this change is around 50%, and in tandem with
some winbindd improvements as part of the same task has achieved around
15x speedup for getpwent.
The lost specification compliance is unlikely to cause a problem for any
known usage of this RPC call.
