Open Source Software

PADL has had a long history of involvement with the open source community. We wrote the LDAP nameservice libraries which are now part of every major Linux distribution, and have made substantial contributions to the security and directory service infrastructure of Darwin, the core of Mac OS X. This page contains links to the open source projects you can download from us. Our research and development page contains further information on some of PADL's open source software.

You can support PADL's continued investment in open source by purchasing a compendium CD-ROM or technical support.

Open source users are encouraged to use Bugzilla to report bugs or suggest enhancements. Please read our guidelines for contributing.
