|
|---|
| 9 |
|
|---|
| 10 | ldb is a LDAP-like embedded database. It is not at all
|
|---|
| 11 | <a href="http://en.wikipedia.org/wiki/Lightweight_Directory_Access_Protocol">LDAP</a>
|
|---|
| 12 | standards compliant, so if you want a standards compliant database then please
|
|---|
| 13 | see the excellent <a href="http://www.openldap.org/">OpenLDAP</a>
|
|---|
| 14 | project.<p>
|
|---|
| 15 |
|
|---|
| 16 | What ldb does is provide a fast database with an LDAP-like API
|
|---|
| 17 | designed to be used within an application. In some ways it can be seen
|
|---|
| 18 | as a intermediate solution between key-value pair databases and a real
|
|---|
| 19 | LDAP database.<p>
|
|---|
| 20 |
|
|---|
| 21 | ldb is the database engine used in Samba4.
|
|---|
| 22 |
|

| 23 | <h2>Features</h2>
|
|---|
| 24 |
|
|---|
| 25 | The main features that separate ldb from other solutions are:
|
|---|
| 26 |
|
|---|
| 27 | <ul>
|
|---|
| 28 | <li>Safe multi-reader, multi-writer, using byte range locking
|
|---|
| 29 | <li><a href="http://en.wikipedia.org/wiki/LDAP_Application_Program_Interface">LDAP-like API</a>
|
|---|
| 30 | <li>fast operation
|
|---|
| 31 | <li>choice of local tdb or remote LDAP backends
|
|---|
| 32 | <li>integration with <a href="http://talloc.samba.org">talloc</a>
|
|---|
| 33 | <li>schema-less operation, for trivial setup
|
|---|
| 34 | <li>modules for extensions (such as schema support)
|
|---|
| 35 | <li>easy setup of indexes and attribute properties
|
|---|
| 36 | <li><a href="http://en.wikipedia.org/wiki/LDAP_Data_Interchange_Format">LDIF</a> for import/export
|
|---|
| 37 | <li>ldbedit tool for database (via LDIF) editing (reminiscent of 'vipw')
|
|---|
| 38 | </ul>
|
|---|
| 39 |
|
|---|
| 40 | <h2>Documentation</h2>
|
|---|
| 41 |
|
|---|
| 42 | Currently ldb is completely lacking in programmer or user
|
|---|
| 43 | documentation. This is your opportunity to make a contribution! Start
|
|---|
| 44 | with the public functions declared in <a
|
|---|
| 45 | href="http://samba.org/ftp/unpacked/ldb/include/ldb.h">ldb.h</a>
|
|---|
| 46 | and the example code in the <a
|
|---|
| 47 | href="http://samba.org/ftp/unpacked/ldb/tools/">tools
|
|---|
| 48 | directory</a>. Documentation in the same docbook format used by Samba
|
|---|
| 49 | would be preferred.
|
|---|
| 50 |
|
|---|
| 51 | <h2>Discussion and bug reports</h2>
|
|---|
| 52 |
|
|---|
| 53 | ldb does not currently have its own mailing list or bug tracking
|
|---|
| 54 | system. For now, please use the <a
|
|---|
| 55 | href="https://lists.samba.org/mailman/listinfo/samba-technical">samba-technical</a>
|
|---|
| 56 | mailing list or the <a href="https://lists.samba.org/mailman/listinfo/ldb">ldb</a>
|
|---|
| 57 | mailing list, and the <a href="http://bugzilla.samba.org/">Samba bugzilla</a> bug tracking system.

| 59 | <h2>Download</h2>
|
|---|
| 60 |
|
|---|
| 61 | You can download the latest release either via rsync or thtough git.<br>
|
|---|
| 62 | <br>
|
|---|
| 63 | To fetch via git see the following guide:<br>
|
|---|
| 64 | <a href="http://wiki.samba.org/index.php/Using_Git_for_Samba_Development">Using Git for Samba Development</a><br>
|
|---|
| 65 | Once you have cloned the tree switch to the v4-0-test branch and cd into the source/lib/ldb directory.<br>
|
|---|
| 66 | <br>
|
|---|
| 67 | To fetch via rsync use these commands:
|
|---|
| 68 |

|
|---|
| 70 | rsync -Pavz samba.org::ftp/unpacked/ldb .
|

|
|---|
| 75 |
