LDAP 3.3

The University of Michigan is pleased to announce release 3.3 of
UM-LDAP, an implementation of the Lightweight Directory Access
Protocol. LDAP is a draft Internet standard directory service
protocol that runs over TCP/IP. It can be used to provide a
stand-alone directory service, or to provide lightweight access to
the X.500 directory. LDAP is defined by RFC 1777 and RFC 1778.

This release includes the following components:

- slapd - a stand-alone LDAP directory server
- slurpd - a stand-alone LDAP replication server
- ldapd - an LDAP-to-X.500 gateway server
- centipede - an LDAP centroid generation and maintenance program
- libldap - an LDAP client library
- liblber - a lightweight BER/DER encoding/decoding library
- ldif tools - data conversion tools for use with slapd
- in.xfingerd - a finger-to-LDAP gateway server
- go500 - a gopher-to-LDAP gateway server for searching
- go500gw - a gopher-to-LDAP gateway server for searching and browsing
- rcpt500 - an email-to-LDAP query responder
- mail500 - an LDAP-capable mailer
- fax500 - an LDAP-capable mailer that supports remote printing
- LDAP tools - A collection of shell-based LDAP utility programs

In addition, there are some contributed components:

- web500 - an HTTP-to-LDAP gateway
- whois++d - a WHOIS++-to-LDAP gateway
- saucer - a simple command-line oriented client program


Changes since release 3.2 of LDAP include

- slurpd has been rewritten as a single process threaded daemon
- ldaptools (ldapsearch, etc) now support the LDIF format
- support for LDAP URLs added to libldap
- improved support for LDAP referrals in libldap
- preliminary test scripts included
- support for additional platforms
- various bug fixes and build fixes
