Free what is ldap software for linux

chpassldapweb is a Web application for changing a password in an LDAP directory. The interface is simple and very functional. The project has protection against denial of service in the LDAP directory.

mod-vhost-ldap is an Apache 2.x module for storing and configuring virtual hosts from LDAP. mod-vhost-ldap project supports DocumentRoot, ScriptAlias, ServerName, ServerAlias, ServerAdmin, and SuexecUserGroup directives.

Its built on top of mod_ldap, so it uses its caching capabilities and can be used with a threaded Apache httpd.

mod_authz_ldap is an Apache LDAP Authorization module.
What it does:
This Apache LDAP authentication/authorization module tries to solve the following problems that other such modules may not solve in all cases:
- Map the short form of the distinguished name of a certificate and its issuer obtained from the environment of mod_ssl to a user distinguished name in an LDAP directory.
- Check the age of a password in an LDAP directory, denying authorization in case - the password is to old.
Authorize a user based on roles or an arbitrary LDAP filter expression.
- Authorize a user based on whether he owns a file or belongs to the group owning a file.
The module can perform an ordinary LDAP authentication using an LDAP bind call, but is incapable of verifying an SHA1 or crypt password hash from the directory, as mod_auth_ldap can.
The module also tries to do reduce LDAP connection overhead by caching a connection between requests (one per server record). This is most likely to improve performance in the case of certificate authentication, as for basic authentication a bind to the directory on a new connection is necessary with every request. Future development may add a cache to improve performance.
Version 0.8 added the ability to use the cache built into some client libraries, most notably OpenLDAP. However, it turned out that the cache for OpenLDAP 2.0.7 does not work, and only causes Apache to dump out the contents of BER buffers instead of authenticating users.
mod_authz_ldap uses some functions from libraries that are only available on Unix systems, it will most probably not work on a Win32 system. There are no plans to fix this problem.
Of course there are other modules that perform LDAP authentication. Not mentionning them here does not mean that they are insignificant, quite the contrary is true. But as far as I know, none of these alternatives does either certificate mapping or password aging.

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();

mod_psldap is an Apache module that performs authentication authorization against an LDAP server using several different means of managing the authentication and authorization processes.
mod_psldap implementation can also manage records through a Web interface, and authenticate against an LDAP server that restricts the user from reading the password and the implementation of Kerberos-based authentication to connect to the LDAP server itself.
Enhancements:
- This release provides AJAX functionality, allowing for the DSML form of the LDAP records to be browsed offline from either the organizational or management tree views.
- A minor issue with recognition of the search scope as defined in the URI has also been addressed, along with the partial introduction of vcard export capabilities.

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.
