INSTALL

-Making and Installing the U-M LDAP Distribution
+Making and Installing the OpenLDAP Distribution
+===============================================
 
-** It is recommended that you read or at least skim through ALL of the
-** instructions in this file before attempting to build the software.
+This file provides brief instructions on how to build and install
+OpenLDAP on UNIX (and UNIX-like) system.  More detailed information
+and instructions can be found in The OpenLDAP Administrator's Guide
+(http://www.openldap.org/doc/admin/).
 
-If you want to build binaries for more than one platform from a single
-source tree, skip ahead to the "Building LDAP For More Than One Platform"
-section near the end of this file. If you are planning to run slapd,
-you should read the "SLAPD and SLURPD Administrator's Guide", found in
-the doc/guides/ directory within the distribution.
+It is recommended that you read, or at least skim through, ALL of the
+instructions in this file before attempting to build the software.
 
-If you simply want to build LDAP for a single machine platform, follow
-these steps:
+It is also recommended you review Frequently Asked Questions
+(http://www.openldap.org/faq/) pages, in particular the Installation
+section (http://www.openldap.org/faq/index.cgi?file=8) and Platform
+Hints (http://www.openldap.org/faq/index.cgi?file=9) should be
+examined.
 
- 1. untar the distribution and cd to the top:
 
-	% zcat ldap-3.3.tar.Z | tar xf -
-	% cd ldap-3.3
+Making and Installing the OpenLDAP Distribution
+-----------------------------------------------
 
-    If you are reading this file, you probably have already done this!
+1.   Unpack the distribution and change directory:
 
+        % tar xfz openldap-VERSION.tgz
+        % cd openldap-VERSION
 
- 2. edit the files Make-common and include/ldapconfig.h.edit to configure
-    the software for your site (the files are well-commented):
+     (replacing VERSION with the appropriate version string).  If you
+     are reading this file, you probably have already done this!
 
-	% vi Make-common
-	% vi include/ldapconfig.h.edit
+2.   Type:
 
-    Note that you should NOT need to edit the Makefile located at the
-    top of the distribution.
+        % ./configure --help
 
-    If you just want to see if things will build, you can leave the
-    configuration alone and change it later.
+     to list available configuration options.   A description of these
+     options is provided in the 'CONFIGURE OPTIONS' section below.
 
-    If you have the ISODE package built and want to build the
-    LDAP-to-X.500 server (ldapd), be sure to uncomment the appropriate
-    lines near the end of the Make-common file.  By default only the
-    stand-alone server, LDAP libraries and client software are built.
+     The configure script uses environmental variables for determining
+     compiler/linker options including:
 
- 3. make the software:
+        Variable        Description     Example
+        CC              C compiler      gcc
+        CFLAGS          C flags         -O -g
+        CPPFLAGS        cpp flags       -I/path/include -Ddef
+        LDFLAGS         ld flags        -L/usr/local/lib
+        LIBS            libraries       -llib
+        PATH            command path    /usr/local/bin:/usr/bin:/bin
 
-	% make
+3.   Configure the build system
 
-    If all goes well, then make will figure out what platform you are on,
-    pick a compiler to use, construct Makefiles, and build everything.
-    If you see a message like "unknown platform..." LDAP has probably not
-    been set up to build on your machine.  See the file build/PORTS for
-    hints on what to do in that case.
+        % [env settings] ./configure [options]
 
-    Note that if your make does not use the Bourne (sh) shell by
-    default when executing internal scripts (reportedly the case on SGI
-    machines at least), you will need to run the make explicitly from
-    within a Bourne shell.  If you a syntax error such as "Missing ]"
-    when you do the make under your usual shell, try this:
+     If all goes well, the configure script with automatically detect
+     the appropriate settings.  However, you may need to specify
+     options and/or environment variables to obtain desired results.
 
-	% sh
-	$ make
+4.   Build dependencies
 
-    If you don't like the some of the platform-specific options chosen
-    by the automatic build process (such as the compiler to use, etc),
-    you can intervene and edit them before anything is actually compiled
-    by explicitly doing a "make platform" step, editing the .make-platform
-    file (actually a link to the file to be edited), and then doing a
-    regular make:
+        % make depend
 
-	% make platform
-	% vi .make-platform
-	% make
+5.   Build the system
 
-    If you want to choose the build platform yourself from among those that
-    the distribution supports, cd to the appropriate directory underneath
-    build/platforms and make from there.  For example, if you are on a
-    machine running SunOS 4.1.4 and you want to force the use of the cc
-    compiler, you would do this:
+        % make
 
-	% cd build/platforms/sunos4-cc
-	% make
+     If all goes well, the system will build as configured.  If not,
+     return to step 3 after reviewing the configuration settings.  You
+     may want to consult the Platform Hints subsection of the FAQ if
+     you have not done so already.
 
-    If you want to run some simple tests after the build is complete, you
-    can do this:
+6.   Test the standalone system
 
-	% make test
+     This step requires the standalone LDAP server, slapd(8), with
+     LDBM support.
 
- 4. install the binaries and man pages.  You may need to be superuser to
-    do this (depending on where you are installing things):
+        % make test
 
-	% su
-	# make install
+     If all goes well, the system has been built as configured.  If
+     not, return to step 4 after reviewing your configuration
+     settings.  You may want to consult the Installation section of
+     the FAQ if you have not done so already.
 
-    That's it!  See the man pages for the individual clients for information
-    on configuring and using them.  Eventually you will probably want to
-    edit the configuration files used by the various clients (installed in
-    the LDAP etc directory).  The files are:
+7.   install the binaries and man pages.  You may need to be come the
+     super-user (e.g. root) to do this (depending on where you are
+     installing things):
 
-	ldapfilter.conf      - search filter configuration
-	ldapfriendly         - mapping of X.500 names to human-friendly names
-	ldapsearchprefs.conf - search object definitions
-	ldaptemplates.conf   - display template definitions
+        % su root -c 'make install'
 
-    There are section 5 man pages for all of these files.
+8.   That's it!
 
+See the OpenLDAP Administrator's Guide and the manual pages for the
+individual applications for configuration and use information. You may
+also want to edit the configuration files used by the various
+components.  These configuration files are located in the OpenLDAP
+configuration directory (normally /usr/local/etc/openldap).
 
-Building LDAP For More Than One Platform
+        ldap.conf               client defaults
+        ldapfilter.conf         search filter configuration
+        ldapsearchprefs.conf    search object definitions
+        ldaptemplates.conf      display template definitions
+        slapd.conf              Standalone LDAP daemon
+        schema/*.schema         Schema Definitions
 
-It is now possible to build LDAP for more than one platform from the same
-source tree.  This is accomplished by some rules in the Makefiles that
-create a shadow (linked) directory tree where the binaries are placed.
 
-Follow these steps for each different platform:
+End of OpenLDAP INSTALL file.
 
- 1. move to the directory that matches the platform and compiler you
-    want to build for and type make.  The directories are all located
-    underneath the build/platforms directory.  If your platform is not
-    there, you may need to do a port - see the build/PORTS file for
-    more information.  For a Sun running SunOS 4.1.4, you might do
-    this:
+$OpenLDAP: pkg/openldap-guide/release/install.sdf,v 1.12 2000/09/09
+21:16:09 kurt Exp $
 
-	% cd build/platforms/sunos4-cc
-	% make links
-
-    This will create a linked source area.
-
-
- 2. move to the new directory and make as for a single platform.  Follow steps
-    1-4 above to accomplish this.  For example:
-
-	% cd obj-sunos4-cc
-	% make
-
-    That's all there is to it.  You can also create the linked source area(s)
-    by just typing "make links" at the top of the distribution, in which case
-    the Makefile will try to automatically determine the platform and
-    compiler.
-
-
-End of LDAP INSTALL file.

+	For a description of what this distribution contains, see the
+	ANNOUNCEMENT file in this directory.  For a description of
+	changes from previous releases, see the CHANGES file in this
+	directory.
 
-    This is the UM-LDAP version 3.3 distribution.  For a description of
-    what this distribution contains, see the ANNOUNCEMENT file in this
-    directory.  For a description of changes from previous releases,
-    see the CHANGES file in this directory.  For a more detailed
-    description of how to make and install the distribution, see the
-    INSTALL file in this directory.  For more information on making and
-    installing slapd, see the "SLAPD and SLURPD Administrator's Guide"
-    in the doc/guides/ directory.
+	This is the first release of 2.0 and includes significant
+	changes from prior releases.  The software may be a little
+	rough around the edges, use with appropriate care.  Those
+	seeking stable LDAP servers may want to use 1.2.
 
-MAKING AND INSTALLING THE DISTRIBUTION
 
-    You should be able to make and install the distribution with a pretty
-    standard default configuration by typing the following commands
+REQUIRED SOFTWARE
+	Build OpenLDAP requires a number of software packages to be
+	preinstalled.  Additional information regarding prerequisite
+	software can be found in the OpenLDAP Administrator's Guide.
+
+	Base system (libraries and tools):
+		Standard C compiler (required)
+		Cyrus SASL 1.5 (recommended)
+		OpenSSL 0.9 (recommended)
+		POSIX REGEX software (required)
 
-	% make
-	% su
-	# make install
+	SLAPD:
+		LDBM compatible datastore (required)
+			[Sleepycat Berkeley DB 3.2 (recommended) or GDBM]
 
-    in this directory.  This should produce something that basically
-    works.
+	SLURPD:
+		LTHREAD compatible thread package
+			[POSIX threads, Mach Cthreads, select others]
 
-    You will probably want to do a little configuration to suit your
-    site, though.  There are two files you might want to edit:
+	CLIENTS/CONTRIB ware:
+		Depends on package.  See per package README.
 
-	Make-common		   This file contains definitions for
-				   where things will be installed, where
-				   to find various things, etc.  If you
-				   want to build an ldap server, you'll
-				   definitely need to edit this file
 
-	include/ldapconfig.h.edit  This file contains #defines used
-				   by many parts of the distribution.
-				   You'll at least want to change
-				   DEFAULT_BASE.
+MAKING AND INSTALLING THE DISTRIBUTION
