LDAP Account Manager (LAM) is a web frontend for managing entries (e.g. users, groups, DHCP settings) stored in an LDAP directory. LAM was designed to make LDAP management as easy as possible for the user. It abstracts from the technical details of LDAP and allows persons without technical background to manage LDAP entries. If needed, power users may still directly edit LDAP entries via the integrated LDAP browser.
Print Release System provides Web-based management of System V printing. It sits between Samba and the System V printing system. It ought to be relatively easy to make it work with other printing systems. After the job is printed, the user needs to consult a Web page that shows their queued jobs, which can be selected and released for printing (or canceled). A record is maintained for each job and, once the user reaches a quota, they can't release any further jobs to the printer.
adv-samba is a PHP class to batch audit SAMBA resources on remote hosts or large LANs. It's a very handy tool during network audits. For example, imagine a LAN with 500 workstations. You want to find any illegal MP3s on company machines. With this tool, you recursively dump the share directory structure. It works with Active Directory authentication too.
