下载OpenLDAP的稳定版

# wget ftp://ftp.openldap.org/pub/OpenLDAP/openldap-release/openldap-2.4.39.tgz

安装依赖软件

为了全面兼容LDAPv3, 需要安装依赖软件, 这些软件的版本建议

http://www.openldap.org/doc/admin24/appendix-recommended-versions.html

1. TLS(Transport Layer Security) service 依赖包, OpenLDAP客户端和服务端都需要安装.

OpenSSL, GnuTLS, or MozNSS(三选一)

OpenSSL is available from http://www.openssl.org/. 

GnuTLS is available from http://www.gnu.org/software/gnutls/. 

Mozilla NSS is available from http://developer.mozilla.org/en/NSS.

安装openssl

# wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz

# tar -zxvf openssl-1.0.1g.tar.gz

# cd openssl-1.0.1g

阅读INSTALL和README

# ./config --prefix=/usr/local --openssldir=/usr/local/ssl

# make

# make install

2. SASL(Simple Authentication and Security Layer) service  依赖包, OpenLDAP客户端和服务端都需要安装.

Cyrus SASL

http://asg.web.cmu.edu/sasl/sasl-library.html

安装sasl

# wget ftp://ftp.andrew.cmu.edu/pub/cyrus-mail/cyrus-sasl-2.1.25.tar.gz

# tar -zxvf cyrus-sasl-2.1.25.tar.gz

# cd cyrus-sasl-2.1.25

阅读INSTALL和README

# ./configure

# make

# make install

********************************************************

* WARNING:

* Plugins are being installed into /usr/local/lib/sasl2,

* but the library will look for them in /usr/lib/sasl2.

* You need to make sure that the plugins will eventually

* be in /usr/lib/sasl2 -- the easiest way is to make a

* symbolic link from /usr/lib/sasl2 to /usr/local/lib/sasl2,

* but this may not be appropriate for your site, so this

* installation procedure won't do it for you.

*

* If you don't want to do this for some reason, you can

* set the location where the library will look for plugins

* by setting the environment variable SASL_PATH to the path

* the library should use.

********************************************************

make[2]: Nothing to be done for `install-data-am'.

make[2]: Leaving directory `/opt/soft_bak/cyrus-sasl-2.1.25'

make[1]: Leaving directory `/opt/soft_bak/cyrus-sasl-2.1.25'

[root@db-172-16-3-150 cyrus-sasl-2.1.25]# ln -s /usr/local/lib/sasl2 /usr/lib/sasl2

sasl版本不对可能导致slapd启动失败, 见/var/log/messages

slapd[15107]: auxpropfunc error version mismatch with plug-in

3. Kerberos Authentication Service

Heimdal or MIT Kerberos V libraries(二选一)

Heimdal Kerberos is available from http://www.pdc.kth.se/heimdal/. 

MIT Kerberos is available from http://web.mit.edu/kerberos/www/.

安装MIT Kerberos V Libraries

# wget http://web.mit.edu/kerberos/www/dist/krb5/1.12/krb5-1.12.1-signed.tar

# tar -xvf krb5-1.12.1-signed.tar 

# tar -zxvf krb5-1.12.1.tar.gz

# cd krb5-1.12.1

# cd src

# ./configure

# make

# make install

4. Database Software

OpenLDAP's slapd BDB and HDB primary database backends require Oracle Corporation Berkeley DB

Berkeley DB download page http://www.oracle.com/technology/software/products/berkeley-db/index.html

http://docs.oracle.com/cd/E17076_03/html/installation/index.html

下载

http://download.oracle.com/otn/berkeley-db/db-6.0.30.tar.gz

安装

# tar -zxvf db-6.0.30.tar.gz

# cd db-6.0.30

# cd dist/buildpkg

# cd build_unix

# ../dist/configure --prefix=/opt/bdb6 --enable-sql

# make

# make install

5. Threads

OpenLDAP supports POSIX pthreads, Mach CThreads, and a number of other varieties.

6. TCP Wrappers

slapd supports TCP Wrappers (IP level access control filters) if preinstalled.

7. 配置ld.so.conf

# vi /etc/ld.so.conf

include ld.so.conf.d/*.conf

/usr/local/lib

/usr/lib/sasl2

/opt/bdb6/lib

# ldconfig 

安装openldap

# tar -zxvf openldap-2.4.39.tgz

# cd openldap-2.4.39

# ./configure --help

# ./configure --prefix=/opt/openldap-2.4.39 --with-threads --with-tls --with-cyrus-sasl

# make depend

# make

# make install

# export MANPATH=/opt/openldap-2.4.39/share/man:$MANPATH

# export MANPATH=/opt/openldap-2.4.39/bin:/opt/openldap-2.4.39/sbin:$PATH
