H1: Building and Installing slapd & slurpd Building and installing slapd requires three simple steps: configuring; making; and installing. The following sections describe each step in detail. If you are reading this guide, chances are you have already obtained the software, but just in case, here's where you can get the latest version of the OpenLDAP package, which includes all of the software discussed in this guide: {{URL: ftp://ftp.openldap.org/pub/OpenLDAP/openldap-release.tgz}} There is also an OpenLDAP Project has an extensive site on the World Wide Web. This sites contains the latest OpenLDAP news, release announcements, and pointers to other resources. You can access the site at: {{URL: http://www.OpenLDAP.org/}} H2: Pre-Build Configuration Before building slapd, be sure to take a look at the README file in the top level directory in the distribution so that you are familiar with the general configuration and make process. Briefly, you should edit the include/ldapconfig.h.edit and Make-common files to contain the site-specific configuration your site requires before making. The next sections discuss these steps in more detail. H3: Editing the {{EX: Make-common}} file All of the general Make-common configuration variables (e.g., ETCDIR, BINDIR, etc.) apply to both slapd and slurpd. There are additional Make-common configuration variables that also affect how slapd and slurpd are built. They are: H4: MAKE_SLAPD This option controls whether slapd and slurpd get built at all. You should set it to yes, like this: E: MAKE_SLAPD = yes H4: SLAPD_BACKENDS This option controls which slapd backend databases get built. You should set it to one or more of the following: *{{EX: DLDAP_LDBM}} This is the main backend. It is a high-performance disk-based database suitable for handling up to a million entries or so. See the LDBMBACKEND and LDBMLIB options below. *{{EX: DLDAP_PASSWD}} This is a simple search-only backend that can be pointed at an {{EX: /etc/passwd}} file. It is intended more as an example than as a real backend. *{{EX: DLDAP_SHELL}} This backend allows the execution of arbitrary system administrator-defined commands in response to LDAP queries. The commands to execute are defined in the configuration file. See Appendix B for more information on writing shell backend programs. Example to enable the LDBM and SHELL backends only: E: SLAPD_BACKENDS= -DLDAP_LDBM -DLDAP_SHELL The default is to build all three backends. Note that building a backend only means that it can be enabled through the configuration file, not that it will automatically be enabled. H4: LDBMBACKEND This option should only be defined if you have enabled the LDBM backend as described above. The LDBM backend relies on a low-level hash or B-tree package for its underlying database. This option selects which package it will use. The currently supported options in order of preference are: *{{EX: DLDBM_USE_DBBTREE}} .This option enables the Berkeley DB package btree database as the LDBM backend. You can get this package from: {{URL: ftp://ftp.cs.berkeley.edu/ucb/4bsd/db.tar.Z}} *{{EX: DLDBM_USE_DBHASH}} .This option enables the Berkeley DB package hash database as the LDBM backend. You can get this package from {{URL ftp://ftp.cs.berkeley.edu/ucb/4bsd/db.tar.Z}} *{{EX: DLDBM_USE_GDBM}} .This option enables GNU dbm as the LDBM backend. You can get this package from {{URL: ftp://prep.ai.mit.edu/pub/gnu/gdbm-1.7.3.tar.gz}} *{{EX: DLDBM_USE_NDBM}} .This option enables the standard UNIX ndbm(3) package as the LDBM backend. This package should come standard on your UNIX system. man ndbm for details. Example to enable the Berkeley DB Btree backend: E: LDBMBACKEND= -DLDBM_USE_DBBTREE The default is -DLDBM_USE_NDBM, since it is the only one available on all UNIX systems. NDBM has some serious limitations, though (not thread-safe, severe size limits), and you are strongly encouraged to use one of the other packages if you can. Note[label='Note to Solaris users: '] If you are running under Solaris 2.x and linking in an external database package (e.g., db or gdbm) it is very important that you compile the package with the {{EX: D_REENTRANT}} flag. If you do not, bad things will happen. If you are using version 1.85 or earlier of the Berkeley db package, you will need to apply the patch found in build/db.1.85.patch to the db source before compiling it. You can do this with a command like this from the db source area: E: patch -p < ldap-source-directory/build/db.1.85.patch H4: LDBMLIB This option should only be defined if you have enabled the LDBM backend as described above, and the necessary library for the LDBMBACKEND option you chose above is not part of the standard C library (i.e., anything other than NDBM). This option specifies the library to link containing the package you selected, and optionally, its location. Example to link with {{EX: libdb.a}}, contained in {{EX: /usr/local/lib}}: E: LDBMLIB= -L/usr/local/lib -ldb H4: THREADS This option is normally set automatically in the {{EX: Make-platform}} file, based on the platform on which you are building. You do not normally need to set it. If you want to use a non-default threads package, you can specify the appropriate {{EX: -Ddefine}} to enable it here. H4: THREADSLIB This option is normally set automatically in the {{EX: Make-platform}} file, based on the platform on which you are building. You do not normally need to set it. If you have set {{EX: THREADS}} to a non-default threads package as described above, you can specify the appropriate {{EX: -Ldirectory}} flag and {{EX: -llibname}} flag needed to link the package here. H4: PHONETIC This option controls the phonetic algorithm used by {{I: slapd}} when doing approximate searches. The default is to use the metaphone algorithm. You can have {{I: slapd}} use the soundex algorithm by setting this variable to {{EX: -DSOUNDEX}}. H3: Editing the {{EX: include/ldapconfig.h}} file In addition to setting the {{EX: LDAPHOST}} and {{EX: DEFAULT_BASE}} defines near the top of this file, there are some slapd-specific defines near the bottom of the file you may want to change. The defaults should be just fine, unless you have special needs. H4: SLAPD_DEFAULT_CONFIGFILE This define sets the location of the default slapd configuration file. Normally, it is set to {{EX: $(ETCDIR)/slapd.conf}}, where {{EX: ETCDIR}} comes from Make-common. H4: SLAPD_DEFAULT_SIZELIMIT This define sets the default size limit on the number of entries returned from a search. This option is configurable via the tailor file, but if you want to change the default, do it here. H4: SLAPD_DEFAULT_TIMELIMIT This define sets the default time limit for a search. This option is configurable via the tailor file, but if you want to change the default, do it here. H4: SLAPD_PIDFILE This define sets the location of the file to which slapd will write its process ID when it starts up. H4: SLAPD_ARGSFILE This define sets the location of the file to which slapd will write its argument vector when it starts up. H4: SLAPD_MONITOR_DN This define sets the distinguished name used to retrieve monitoring information from {{I: slapd}}. See section 7 for more details. H4: SLAPD_LDBM_MIN_MAXIDS This define is only relevant to the LDBM backend. It sets the minimum number of entry IDs that an index entry will contain before it becomes an allIDs entry. See Section 9.1 for more details. H2: Making the Software Once you have edited the {{EX: include/ldapconfig.h.edit}} file and the Make-common file (see the top level {{EX: README}} file in the distribution), you are ready to make the software. From the top level LDAP source directory, type E: make You should examine the output of this command carefully to make sure everything is built correctly. Note that this command builds the LDAP libraries and associated clients as well as slapd and slurpd. Note that the LDAP distribution can support making for multiple platforms from a single source tree. If you want to do this, consult the {{EX: INSTALL}} file in the top level distribution directory. H2: Installing the Software Once the software has been properly configured and successfully made, you are ready to install it. You will need to have write permission to the installation directories you specified in the {{EX: Make-common}} file. Typically, the installation is done as root. From the top level LDAP source directory, type E: make install You should examine the output of this command carefully to make sure everything is installed correctly. Slapd, slurpd, and their configuration files, {{EX: slapd.conf}}, {{EX: slapd.at.conf}}, and {{EX: slapd.oc.conf}} will be installed in the {{EX: ETCDIR}} directory you specified in the {{EX: Make-common}} file. This command will install the entire LDAP distribution. If you only want to install slapd and slurpd, you could do something like this: E: (cd servers/slapd; make install) E: (cd servers/slurpd; make install) Note: The installation process installs configuration files as well as binaries. Existing configuration files are first moved to a name with a dash '-' appended, e.g., {{EX: slapd.conf}} is moved to {{EX: slapd.conf-}}. If you install things twice, however, you can lose your existing configuration files.
