The Infotrope ACAP Server is an implementation of RFC2244, complete with asynchronous notification of changes, stored search results, ACLs, and data inheritance, etc. It supports TLS and SASL encryption as well as the entire base standard, plus a few optional extensions. ACAP allows applications to store configuration data in a way that is standard, fully interoperable, and easily managed by users, administrators, and technical support teams alike. Infotrope's key features include the ability to randomly crash the server without data loss, and backing up of data (even while it's being written) without losing integrity.
ldap-abook is an LDAP-based addressbook application, intended for users wishing to maintain a centralized server based addressbook. It provides a schema for an LDAP directory, a Perl library module, and a CGI script. The Web interface is used to view, add, modify, and delete entries. Any LDAP-aware email client (eg. Netscape Messenger, Microsoft Outlook, Lotus Notes, etc.) can be configured to look up email addresses on the LDAP server. The package also includes a Perl script which can be used to dump the directory onto a PalmOS device.
