Free ldap user software for linux

LDAP User Management System (LUMS) provides a set of basic LDAP API functions for PHP and a strong configuration language. The project can then be used to create Web services or can be used in any PHP script.
The language allows the administrator to define LDAP object types along with their corresponding attributes.
Each attribute may be defined as required as multivalued with a type (string, binary, dn, telephone, mail, etc.) and can be user inserted, constant, auto incremented, or function created. Attribute uniqueness is supported.
It exports the following LDAP operations:
- function LUMS_ldap_search($L_binddn,$L_bindpassword,$L_basedn,$L_scope,$L_filter,$L_attrs_array)
Returns an $info object with the search results or a string with an error
- function LUMS_ldap_add_entry($L_binddn, $L_bindpassword,$L_object_type,$L_entrydn,$L_entry_info)
Returns 0 for success or string with error
- function LUMS_ldap_change_password($L_binddn, $L_bindpassword,$L_entrydn,$L_newpassword)
Returns 0 for success or string with error
- function LUMS_ldap_modify_entry($L_binddn, $L_bindpassword, $L_object_type, $L_entrydn, $L_change_info)
Returns 0 for success or string with error
- function LUMS_ldap_delete_entry($L_binddn, $L_bindpassword, $L_object_type, $L_entrydn)
Returns 0 for success or string with error
- function LUMS_ldap_rename_entry($L_binddn, $L_bindpassword, $L_object_type, $L_entrydn, $L_newrdn, $L_newparent, $L_deleteoldrdn)
Enhancements:
- Add a virtual attribute which is not stored on ldap but can be useful when creating other attribute values
- Add mapping between an indexing attribute value to other attribute values
- Fix a few typos
- Perform the same checks for all value types not just uservalue
- Lower case all passed attribute names

Pldap short from PAM LDAP Module is an experimental attempt at writing a new LDAP authentication module for PAM. It is currently beta code, and only implements the basic elements of LDAP authentication.
However, it does provide all the elements of a PAM module, and can be used to authenticate and authorise users against an LDAP database.
Main features:
- Simple bind against a directory to authenticate a user
- User defined templates for matching a userid to a DN
- Configurable filters for searching groups to authorise a login
- Change password capability
- TLS security
- Support for Linux, NetBSD, FreeBSD and Solaris
- Links to both the Solaris and OpenLDAP client libraries
Enhancements:
- Support for Solaris and FreeBSD
- Configure fixes to determine client LDAP libraries
- Compile under Redhat FC5
- Minor Bug Fixes

LDAPab is a Web-based address book for small companies. LDAPab features a public address book which is writable for all company staff and a personal address book for each staff member. LDAPab requires an existing LDAP server to authenticate users.

nss_ldap is an RFC 2307-compliant set of C library extensions.
The resolution of the entities defined in RFC 2307 is generally performed by a set of UNIX C library calls (such as getpwnam() to return the attributes of a user).
The nss_ldap module provides the means for Solaris and Linux workstations to this information (such as users, hosts, and groups) from LDAP directories.
The module is the reference implementation of RFC 2307, and has been studied by vendors such as Sun (who developed the original Name Service Switch interface).
Main features:
- Support for the RFC 2307/RFC 2307bis (including netgroups) as well as user-defined schema
- Common implementation across platforms
- Support for Kerberos and SSL authentication, integrity and privacy
- Configuration file compatibility with pam_ldap
- Bootstraps from the DNS using SRV records
- Support for AIX, glibc, IRS and ONC+ name service switches
- Support for RFC 2307bis groups (including nested groups)
- Specific Active Directory support including incremental retrieval of multi-valued attributes
- Directory-based authentication for platforms that lack PAM (AIX 4.3.3)

mod_mldap is a simple LDAP authentication module for Apache 2.

Quick installtion of the dynamic module:

As root, run:
make install

It may be necessary to edit the include and APXS paths in
the Makefile.

Config options:

* MLDAP_URL LDAP URL.

* MLDAP_userAttr LDAP user name attibute. The default is "uid".

* MLDAP_pwAttr LDAP encrypted password attribute. Default
"UserPassword".

* MLDAP_logLevel Set to 1000 or above for debug messages.
The default is 0 (only error messages).

* MLDAP_Authoritative Set to "Off" to pass control to other authentication
modules if authentication fails. Default is "On".

Example (.htaccess):

AuthType Basic
AuthName TopSecret
MLDAP_URL ldap://127.0.0.1/dc=narpes,dc=com??sub?(objectClass=uidObject)
Require valid-user

Ruby/LDAP is an extension module for Ruby that provides the interface to LDAP libraries such as OpenLDAP.

It provides the interface to some LDAP libraries (for example, OpenLDAP, UMich LDAP, Netscape SDK, ActiveDirectory). The common API for application development is described in RFC1823 and most libraries comply with it. Ruby/LDAP supports those libraries.

Samba::LDAP is a Perl module to manage a Samba PDC with an LDAP Backend.

SYNOPSIS

use Carp;
use Samba::LDAP;

my $samba = Samba::LDAP->new()
or croak "Cant create objectn";
my $domain = $samba->get_local_sid();
