OpenLDAP
====
this is Openldap binding in GO language. I don't work any more with golang, so, please fork this project.
Installation :
-----
Installation is easy and very quick, as you can see :
# install openldap library and devel packages
sudo apt-get install libldap libldap2-dev # debian/ubuntu.
sudo urpmi openldap-devel # fedora, RH, ...
# install go
go get github.com/mqu/openldap
# verify you've got it :
(cd $GOPATH ; go list ./...) | grep openldap
Usage
----
- Look a this [exemple](https://github.com/mqu/openldap/blob/master/_examples/test-openldap.go).
- a more complex example making [LDAP search](https://github.com/mqu/openldap/blob/master/_examples/ldapsearch.go) that mimics ldapsearch command, printing out result on console.
Doc:
---
- run _go doc openldap_,
- will come soon, complete documentation in this [Wiki](https://github.com/mqu/openldap/wiki).
- look at [_examples/](https://github.com/mqu/openldap/blob/master/_examples/)*.go to see how to use this library.
Todo :
----
- thread-safe test,
- complete LDAP:GetOption() and LDAP:SetOption() method : now, they work only for integer values,
- avoid using deprecated function (see LDAP_DEPRECATED flag and "// DEPRECATED" comments in *.go sources),
- write some tests,
- verify memory leaks (Valgrind),
- support LDIF format (in, out),
- add support for external commands (ldapadd, ldapdelete)
- create an LDAP CLI (command line interface), like lftp, with commands like shell,
- a nice GUI with GTK,
- proxy, server,
- what else ?
Links :
----
- goc : http://code.google.com/p/go-wiki/wiki/cgo (how to bind native libraries to GO)
- Openldap library (and server) : http://www.openldap.org/
- Pure Go [LDAP](https://github.com/mmitton/ldap) library, with [ASN1](https://github.com/mmitton/asn1-ber) support.

** WORK IN PROGRESS!

** OpenLDAP reentrancy/thread-safeness should be dynamically
** checked using ldap_get_option().
**
** The -lldap implementation is not thread-safe.
**
** The -lldap_r implementation is:
** LDAP_API_FEATURE_THREAD_SAFE (basic thread safety)
** but also be:
** LDAP_API_FEATURE_SESSION_THREAD_SAFE
** LDAP_API_FEATURE_OPERATION_THREAD_SAFE
**
** The preprocessor flag LDAP_API_FEATURE_X_OPENLDAP_THREAD_SAFE
** can be used to determine if -lldap_r is available at compile
** time. You must define LDAP_THREAD_SAFE if and only if you
** link with -lldap_r.
**
** If you fail to define LDAP_THREAD_SAFE when linking with
** -lldap_r or define LDAP_THREAD_SAFE when linking with -lldap,
** provided header definations and declarations may be incorrect.
