Free ldap backend software for linux

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

AcuLaser C900 CUPS backend provides a LINUX CUPS package (incl. PPD-file) for the EPSON AcuLaser C900.
It is built around the avasys pipsplus driver. The project supports i386 and 32-bit compatible x86_64 LINUX systems (deb/rpm/tgz/gentoo/slack)
There are positive feedbacks for:
- SuSE
- Mandriva
- Slackware
- Red Hat
- Fedora Core
- Debian, Ubuntu
- Gentoo
The included installer will:
- Check for missing packages
- download and install the mandatory epkowa packages automatically
- provide a dummy lpr-package to resolve dependencies
- account for the different Ditros (BSD - System V - Gentoo) and configure the run-levels accordingly
- give suggestions for appropriate URIs for the printer installation
- call the distribution specific CUPS tools (YaST2, printerdrake, kprinter, gnome-cups-config)
Main features:
- Bundling of pages (large documents sometimes "hang")
- generic multiple local printer support
- URI handling for proper interface (usblp) allocation
- installation of XML files for plain foomatic support
- better hotplugging behavior
- networking (IPP, SMB) support through a local pseudo-interface
Enhancements:
- The regular print mode will be selected with every reboot or runlevel change.

LDAP Shell is an interactive LDAP shell written in Perl and allowing basic administrative functionality, such as crawling the directory tree and modifying entries.
It is composed of two parts: Net::LDAP::Config, and ldapsh.
Net::LDAP::Config is a library for simplifying and centralizing access to your LDAP repositories. Instead of having every single script ask for your ldap server and search base, or have it hard coded, you can simply use this library:
my $config = Net::LDAP::Config->new("default");
Its got a couple other nice features, like the fact that it caches your LDAP UID (per host), so you should only ever have to type it in once. Its pretty well documented, so perldoc Net::LDAP::config should get you the rest of the way.
ldapsh, and its corresponding library Net::LDAP::Shell, provide (shockingly) the shell behaviour. When run, ldapsh drops you into a (very simple) interpreter.
Even given its simplicity, though, ldapsh is still very useful: You can use it to walk your LDAP tree, you can clone existing objects (using the clone command), remove objects (can you guess the command?), and create new objects using new.
The new command, when provided one or more objectclasses, will automatically retrieve the required and optional attributes for those objectclasses, which can be a great time-saver.
Enhancements:
- A lot of cleanup, some new commands, and Term::ReadKey support.

HP3300c SANE backend is a Linux SANE backend for the HP3300c USB color scanner.
Support for other scanners with very similar chipsets, like the HP3400c, HP4300c and the Agfa Touch is also planned.
The HP3300C is an USB color scanner. It is externally powered. On the front is has two buttons that can trigger the scanner software to make either a scan or a copy. It has a horizontal resolution of 600 DPI (5300 pixels) and a vertical resolution of 1200 lines per inch.
It has the following chipset:
- NIPEDC0804, two rows of 20 pins along bottom and top edge. It has a 12.000 MHz crystal mounted close to it. This chip was mentioned as an interface chip on an electronics web page. The pinout of this chip is very similar to the Genesys Logic GL640USB chip (datasheet available).
- KM2Q65R, T224162B-28J, 100 Mhz, a 256k x 16 EDO DRAM chip from Taiwan - Memory Technology (TMTech) (datasheet available). The HP3400C has a EliteMT 100 MHz M11B416256A, also a 256k x 16 DRAM chip.
- ESIC ES8100QA, pins on all four sides, the analog-front-end. Also the Wolfson Micro WM8143 (datasheet available) has been reported. These two chips seem to be completely compatible.
- NIASH00014, pins on all four sides, 100 in total. This is the main controller IC. It has a 20.000 MHz crystal on pins 61 and 62. Two HP3400c scanners have been reported to contain a NIASH00019 chip.
Enhancements:
- Added device and company ID for Silitek derivate
- updated testtool_xfer.c

system-tools-backends is a package for GNOME.

HP ScanJet 3900 series backend is an application and backend for linux that allows to use HP scanjet series 3900 scanners and, basically, all those controlled by Realtek RTS8822L chipset.
HP ScanJet 3900 series backend application is in early phase of development. Four files are included, two (binary and sources) for the application and two more for SANE backend.
Enhancements:
- Added support for scanner: HP ScanJet G3010 (similar to hp4370)
- Added initial support for scanner: BenQ 5550T (New chipset: RTS8823L-01E).
- Fixed bug related to stepper motor, programming smearing curves for backtracking.
- Implemented algorithm to detect installed RAM type.
- Implemented a better code to read/write in DMA.
- Added some scripts for users, to update, compile and install sources.
