LDAP 3.1

The University of Michigan is pleased to announce release 3.1 of
UM-LDAP, an implementation of the Lightweight Directory Access
Protocol. LDAP is a proposed Internet standard protocol for
accessing X.500, that runs over TCP/IP. It is similar in function
to the DAS and DIXIE protocols described in RFC's 1202 and 1249,
respectively. LDAP itself is defined by RFC 1487 and RFC 1488.

This release includes the following components:

- ldapd - An LDAP-to-X.500 server
- libldap - An LDAP client library
- liblber - A lightweight BER/DER encoding/decoding library
- in.xfingerd, an LDAP-based finger daemon
- go500 - A gopher index server to LDAP gateway for local searching
- go500gw - A general gopher to LDAP gateway for browsing and searching
- ud - A tty-based LDAP client
- rcpt500 - An email LDAP query responder
- mail500 - An LDAP-capable mailer
- fax500 - An LDAP-capable mailer that support remote printing
- LDAP tools - A collection of shell-based LDAP utility programs

In addition, there are some contributed components:

- web500 - A web to LDAP gateway
- whois++d - A local WHOIS++ to LDAP gateway
- saucer - a simple command-line oriented client program

ISODE (either version 8.0 or IC) are required to build the server,
but the clients and associated libraries can be built separately
without having ISODE.


Changes from release 3.0 of LDAP include

- source tree has been completely restructured
- configuration/installtion procedure has been simplified
- man page documentation has been rewritten and expanded
- addition of display template support in libldap, allowing
easy run-time configuration of how to display entries
- addition of search preference support in libldap
- addition of shell-based ldap utility programs
- addition of Connectionless LDAP (CLDAP) support
- full support for ansi-style prototypes in libldap
(non-prototype systems are still supported through
the use of the unproto utility)
- support for BER and DER and big TAGS in liblber
- addition of a contributed web to X.500 gateway
- many bug fixes
