+This directory contains Samba specific extensions to ldb. It also
+serves as example code on how to extend ldb for your own application.
+
+The main extension Samba uses is to provide ldif encode/decode
+routines for specific attributes, so users can get nice pretty
+printing of attributes in ldbedit, while the attributes are stored in
+the standard NDR format in the database.

+Here is how to use gcov to test code coverage in ldb.
+
+Step 1: build ldb with gcov enabled
+
+     make clean all WITH_GCOV=1
+
+Step 3: run the test suite
+     make test-tdb
+
+Step 4: produce the gcov report
+     make gcov
+
+Step 5: read the summary reports
+     less *.report.gcov
+
+Step 6: examine the per-file reports
+     less ldb_tdb\#ldb_tdb.c.gcov
+
+You can also combine steps 2 to 4 like this:
+
+     make clean all test-tdb gcov WITH_GCOV=1
+
+Note that you should not expect 100% coverage, as some error paths
+(such as memory allocation failures) are very hard to trigger. There
+are ways of working around this, but they are quite tricky (they
+involve allocation wrappers that "fork and fail on malloc").
+
+The lines to look for in the per-file reports are the ones starting
+with "#####". Those are lines that are never executed.

+      of space required to store an array of SIZE_MAX is allocated on the
+      stack.  Assuming a 32-bit (64 bit) integer for size_t, this needs
+      only 32 * sizeof(stack_node) == 256 bytes (for 64 bit: 1024 bytes).
+      Pretty cheap, actually.
+
+   2. Chose the pivot element using a median-of-three decision tree.
+      This reduces the probability of selecting a bad pivot value and
+      eliminates certain extraneous comparisons.
+
+   3. Only quicksorts TOTAL_ELEMS / MAX_THRESH partitions, leaving
+      insertion sort to order the MAX_THRESH items within each partition.
+      This is a big win, since insertion sort is faster for small, mostly
+      sorted array segments.
+
+   4. The larger of the two sub-partitions is always pushed onto the
+      stack first, with the algorithm then concentrating on the
+      smaller partition.  This *guarantees* no more than log (total_elems)

+\mainpage ldb
+
+\section Overview
+
+ldb is a LDAP-like embedded database. It is not at all LDAP 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.
+
+\section Features
+
+The main features that separate ldb from other solutions are:
+ - Safe multi-reader, multi-writer, using byte range locking
+ - LDAP-like API
+ - fast operation
+ - choice of local tdb, local sqlite3 or remote LDAP backends
+ - integration with <a href="http://talloc.samba.org">talloc</a>
+ - schema-less operation, for trivial setup
+ - modules for extensions (such as schema support)
+ - easy setup of indexes and attribute properties
+ - ldbedit tool for database editing (reminiscent of 'vipw')
+ - ldif for import/export
+
+\section Documentation
+
+ldb has limited programmer and administrator documentation:
+ - a list of <a href="globals_func.html">functions</a>
+ - a list of <a href="examples.html">examples</a>
+ - a list of <a href="annotated.html">data structures</a>
+ - a list of <a href="globals_defs.html">constants</a>
+
+If you need more information than is presented in this document, you
+may wish to look at the source code, especially the source code in the
+<a href="http://samba.org/ftp/unpacked/samba4/source/lib/ldb/tools/">tools directory</a>. 
+
+ldb makes use of the LDAP Data Interchange Format (LDIF), which is
+documented in <a href="http://www.ietf.org/rfc/rfc2849.txt">RFC
+2849</a>. 
+
+\section Support
+
+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.
+

+
+	<para>
+ldb is a light weight embedded database library and API. With a
+programming interface that is very similar to LDAP, ldb can store its
+data either in a tdb(3) database or in a real LDAP database.
+	</para>
+
+	<para>
+When used with the tdb backend ldb does not require any database
+daemon. Instead, ldb function calls are processed immediately by the
+ldb library, which does IO directly on the database, while allowing
+multiple readers/writers using operating system byte range locks. This
+leads to an API with very low overheads, often resulting in speeds of
+more than 10x what can be achieved with a more traditional LDAP
+architecture.
+	</para>
+
+	<para>
+In a taxonomy of databases ldb would sit half way between key/value
+pair databases (such as berkley db or tdb) and a full LDAP
+database. With a structured attribute oriented API like LDAP and good
+indexing capabilities, ldb can be used for quite sophisticated
+applications that need a light weight database, without the
+administrative overhead of a full LDAP installation.
+	</para>
+
+	<para>
+Included with ldb are a number of useful command line tools for
+manipulating a ldb database. These tools are similar in style to the
+equivalent ldap command line tools.
+	</para>
+
+	<para>
+In its default mode of operation with a tdb backend, ldb can also be
+seen as a "schema-less LDAP". By default ldb does not require a
+schema, which greatly reduces the complexity of getting started with
+ldb databases. As the complexity of you application grows you can take
+advantage of some of the optional schema-like attributes that ldb
+offers, or you can migrate to using the full LDAP api while keeping
+your exiting ldb code.
+	</para>
+
+	<para>
+If you are new to ldb, then I suggest starting with the manual pages
+for ldbsearch(1) and ldbedit(1), and experimenting with a local
+database. Then I suggest you look at the ldb_connect(3) and
+ldb_search(3) manual pages.

+This test code requires a tdb that is configured for to use the asq module.
+You can do that adding the following record to a tdb:
+
+dn: @MODULES
+@LIST: asq
+
+Other modules can be used as well (like rdn_name for example)
+
+The uidNumber 0 and the gidNumber 0 are considered invalid.
+
+The user records should contain the followin attributes:
+uid (required)			the user name
+userPassword (optional)		the user password (if not present "LDB" is
+				returned in the password field)
+uidNumber (required)		the user uid
+gidNumber (required)		the user primary gid
+gecos (optional)		the GECOS
+homeDirectory (required)	the home directory
+loginShell (required)		the login shell
+memberOf (required)		all the groups the user is member of should
+				be reported here using their DNs. The
+				primary group as well.
+
+The group accounts should contain the following attributes:
+cn (required)			the group name
+uesrPassword (optional)		the group password (if not present "LDB" is
+				returned in the password field)
+gidNumber (required)		the group gid
+member (optional)		the DNs of the member users, also the ones

+<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/ldb/include/ldb.h">ldb.h</a>
+and the example code in the <a
+href="http://samba.org/ftp/unpacked/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 have its own mailing list or bug tracking system. 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.
+
