<h1>ldb</h1>
|
|
|
|
ldb is a LDAP-like embedded database. It is not at all
|
|
<a href="http://en.wikipedia.org/wiki/Lightweight_Directory_Access_Protocol">LDAP</a>
|
|
standards compliant, so if you want a standards compliant database then please
|
|
see the excellent <a href="http://www.openldap.org/">OpenLDAP</a>
|
|
project.<p>
|
|
|
|
What ldb does is provide a fast database with an LDAP-like API
|
|
designed to be used within an application. In some ways it can be seen
|
|
as a intermediate solution between key-value pair databases and a real
|
|
LDAP database.<p>
|
|
|
|
ldb is the database engine used in Samba4.
|
|
|
|
<h2>Features</h2>
|
|
|
|
The main features that separate ldb from other solutions are:
|
|
|
|
<ul>
|
|
<li>Safe multi-reader, multi-writer, using byte range locking
|
|
<li><a href="http://en.wikipedia.org/wiki/LDAP_Application_Program_Interface">LDAP-like API</a>
|
|
<li>fast operation
|
|
<li>choice of local tdb or remote LDAP backends
|
|
<li>integration with <a href="http://talloc.samba.org">talloc</a>
|
|
<li>schema-less operation, for trivial setup
|
|
<li>modules for extensions (such as schema support)
|
|
<li>easy setup of indexes and attribute properties
|
|
<li><a href="http://en.wikipedia.org/wiki/LDAP_Data_Interchange_Format">LDIF</a> for import/export
|
|
<li>ldbedit tool for database (via LDIF) editing (reminiscent of 'vipw')
|
|
</ul>
|
|
|
|
<h2>Documentation</h2>
|
|
|
|
Currently ldb is completely lacking in programmer or user
|
|
documentation. This is your opportunity to make a contribution! Start
|
|
with the public functions declared in <a
|
|
href="http://samba.org/ftp/unpacked/samba4/source/lib/ldb/include/ldb.h">ldb.h</a>
|
|
and the example code in the <a
|
|
href="http://samba.org/ftp/unpacked/samba4/source/lib/ldb/tools/">tools
|
|
directory</a>. Documentation in the same docbook format used by Samba
|
|
would be preferred.
|
|
|
|
<h2>Discussion and bug reports</h2>
|
|
|
|
ldb does not currently have its own mailing list or bug tracking
|
|
system. For now, please use the <a
|
|
href="https://lists.samba.org/mailman/listinfo/samba-technical">samba-technical</a>
|
|
mailing list, and the <a href="http://bugzilla.samba.org/">Samba
|
|
bugzilla</a> bug tracking system.
|
|
|
|
<h2>Download</h2>
|
|
|
|
You can download the latest release either via rsync or anonymous
|
|
svn. To fetch via svn use the following commands:
|
|
|
|
<pre>
|
|
svn co svn://svnanon.samba.org/samba/branches/SAMBA_4_0/source/lib/ldb ldb
|
|
svn co svn://svnanon.samba.org/samba/branches/SAMBA_4_0/source/lib/tdb tdb
|
|
svn co svn://svnanon.samba.org/samba/branches/SAMBA_4_0/source/lib/talloc talloc
|
|
svn co svn://svnanon.samba.org/samba/branches/SAMBA_4_0/source/lib/replace libreplace
|
|
</pre>
|
|
|
|
To fetch via rsync use these commands:
|
|
|
|
<pre>
|
|
rsync -Pavz samba.org::ftp/unpacked/ldb .
|
|
rsync -Pavz samba.org::ftp/unpacked/tdb .
|
|
rsync -Pavz samba.org::ftp/unpacked/talloc .
|
|
rsync -Pavz samba.org::ftp/unpacked/libreplace .
|
|
</pre>
|
|
