.TH SLAPD.CONF 5 "5 August 1999" "OpenLDAP LDVERSION" .SH NAME slapd.conf \- configuration file for slapd, the stand-alone LDAP daemon .SH SYNOPSIS ETCDIR/slapd.conf .SH DESCRIPTION The file .B ETCDIR/slapd.conf contains configuration information for the .BR slapd (8) daemon. This configuration file is also used by the .BR slurpd (8) replication daemon and by the LDBM indexing utilities .BR ldif2ldbm (8), .BR ldif2index (8), .BR ldif2id2entry (8), and .BR ldif2id2children (8). .LP The .B slapd.conf file consists of a series of global configuration options that apply to .B slapd as a whole (including all backends), followed by zero or more database backend definitions that contain information specific to a backend instance. .LP The general format of .B slapd.conf is as follows: .LP .nf # comment - these options apply to every database # first database definition & configuration options database # subsequent database definitions & configuration options ... .fi .LP As many backend-specific sections as desired may be included. Global options can be overridden in a backend (for options that appear more than once, the last appearance in the .B slapd.conf file is used). Blank lines and comment lines beginning with a `#' character are ignored. If a line begins with white space, it is considered a continuation of the previous line. .LP Arguments on configuration lines are separated by white space. If an argument contains white space, the argument should be enclosed in double quotes. If an argument contains a double quote (`"') or a backslash character (`\\'), the character should be preceded by a backslash character. .LP The specific configuration options available are discussed below in the Global Configuration Options, General Backend Options, LDBM Backend-Specific Options, Shell Backend-Specific Options, and Password Backend-Specific Options sections. Refer to "The SLAPD and SLURPD Administrator's Guide" for more details on the slapd configuration file. .SH GLOBAL CONFIGURATION OPTIONS Options described in this section apply to all backends, unless specifically overridden in a backend definition. Arguments that should be replaced by actual text are shown in brackets <>. .TP .B access to [ by ]+ Grant access (specified by ) to a set of entries and/or attributes (specified by ) by one or more requestors (specified by ). Refer to "The SLAPD and SLURPD Administrator's Guide" for information on using the .B slapd access-control mechanisms. .TP .B attribute [] { bin | ces | cis | tel | dn } Associate a syntax with an attribute name. By default, an attribute is assumed to have syntax .BR cis . An optional alternate name can be given for an attribute. The possible syntaxes and their meanings are: .RS .RS .PD 0 .TP .B bin binary .TP .B ces case exact string .TP .B cis case ignore string .TP .B tel telephone number string .TP .B dn distinguished name .PD .RE .RE .TP .B defaultaccess [self]{ none | compare | search | read | write } Specify the default access to grant requestors not matched by any other access line. The default behavior is to grant read access. .TP .B idletimeout Specify the number of seconds to wait before forcibly closing an idle client connections. A idletimeout of 0 disables this feature. The default is 0. .TP .B include Read additional configuration information from the given file before continuing with the next line of the current file. .TP .B pidfile The ( absolute ) name of a file that will hold the .B slapd server's process ID ( see .BR getpid (2) ) if started without the debugging command line option. .TP .B argsfile The ( absolute ) name of a file that will hold the .B slapd server's command line options if started without the debugging command line option. .TP .B locale { | on | off } Obey 's character classification and case conversion; i.e. the .BR locale (5) LC_CTYPE category. See .BR locale (5) for details about locales. "on" takes the locale from the environment, typically $LANG or $LC_CTYPE, and will only work properly if slapd will run with the same environment variables as when the database was generated. "off" (the default setting) resets to the initial "C" locale. .TP .B loglevel Specify the level at which debugging statements and operation statistics should be syslogged (currently logged to the .BR syslogd (8) LOG_LOCAL4 facility). Log levels are additive, and available levels are: .RS .RS .PD 0 .TP .B 1 trace function calls .TP .B 2 debug packet handling .TP .B 4 heavy trace debugging .TP .B 8 connection management .TP .B 16 print out packets sent and received .TP .B 32 search filter processing .TP .B 64 configuration file processing .TP .B 128 access control list processing .TP .B 256 stats log connections/operations/results .TP .B 512 stats log entries sent .TP .B 1024 print communication with shell backends .TP .B 2048 entry parsing .PD .RE .RE .TP .B objectclass requires allows Define the schema rules for the object class named . These are used in conjunction with the schemacheck option. .TP .B referral Specify the referral to pass back when .BR slapd (8) cannot find a local database to handle a request. If specified multiple times, each url is provided. .TP .B schemacheck { on | off } Turn schema checking on or off. The default is on. .TP .B sizelimit Specify the maximum number of entries to return from a search operation. The default size limit is 500. .TP .B srvtab Specify the srvtab file in which the kerberos keys necessary for authenticating clients using kerberos can be found. This option is only meaningful if you are using Kerberos authentication. .TP .B timelimit Specify the maximum number of seconds (in real time) .B slapd will spend answering a search request. The default time limit is 3600. .SH TLS OPTIONS If .B slapd is build with support for Transport Layer Security, there are more options you can specify. .TP .B TLSCipherSuite Permits configuring what ciphers will be accepted and the preference order. should be a cipher specification for OpenSSL. Example: TLSCipherSuite HIGH:MEDIUM:+SSLv2 To check what ciphers a given spec selects, use: openssl ciphers -v .TP .B TLSCertificateFile Specifies the file that contains the .B slapd server certificate. .TP .B TLSCertificateKeyFile Specifies the file that contains the .B slapd server private key that matches the certificate stored in the .B TLSCertificateFile file. Currently, the private key must not be protected with a password, so it is of critical importance that it is protected carefully. .SH GENERAL BACKEND OPTIONS Options in this section only apply to the configuration file section for the backend in which they are defined. They are supported by every type of backend. .TP .B database Mark the beginning of a new database instance definition. should be one of .B ldbm, .B shell, or .B passwd depending on which backend will serve the database. .TP .B lastmod on | off Controls whether .B slapd will automatically maintain the modifiersName, modifyTimestamp, creatorsName, and createTimestamp attributes for entries. By default, lastmod is on. .TP .B readonly on | off This option puts the database into "read-only" mode. Any attempts to modify the database will return an "unwilling to perform" error. By default, readonly is off. .TP .B replica host=[:port] "binddn=" bindmethod=simple | .B kerberos [credentials=] [srvtab=] .br Specify a replication site for this database. Refer to "The SLAPD and SLURPD Administrator's Guide" for detailed information on setting up a replicated .B slapd directory service. .TP .B replogfile Specify the name of the replication log file to log changes to. The replication log is typically written by .BR slapd (8) and read by .BR slurpd (8). See .BR slapd.replog (5) for more information. .TP .B rootdn Specify the DN of an entry that is not subject to access control or administrative limit restrictions for operations on this database. .TP .B rootpw Specify a password (or hash of the password) for the rootdn. This option accepts all password formats known to the server including \fB{SHA}\fP, \fB{MD5}\fP, \fB{CRYPT}\fP, and cleartext. Cleartext passwords are not recommended. .TP .B suffix Specify the DN suffix of queries that will be passed to this backend database. Multiple suffix lines can be given and at least one is required for each database definition. .TP .B updatedn This option is only applicable in a slave .B slapd. It specifies the DN allowed to make changes to the replica (typically, this is the DN .BR slurpd (8) binds as when making changes to the replica). .TP .B updateref Specify the referral to pass back when .BR slapd (8) is asked to modify a replicated local database. If specified multiple times, each url is provided. .SH LDBM BACKEND-SPECIFIC OPTIONS Options in this category only apply to the LDBM backend database. That is, they must follow a "database ldbm" line and come before any subsequent "database" lines. The LDBM backend is a high-performance database that makes extensive use of indexing and caching to speed data access. .TP .B cachesize Specify the size in entries of the in-memory cache maintained by the LDBM backend database instance. The default is 1000 entries. .TP .B dbcachesize Specify the size in bytes of the in-memory cache associated with each open index file. If not supported by the underlying database method, this option is ignored without comment. The default is 100000 bytes. .TP .B dbcachenowsync Specify that database writes should not be immediately synchronized with in memory changes. Enabling this option may improve performance at the expense of data security. .TP .B directory Specify the directory where the LDBM files containing the database and associated indexes live. The default is .B /usr/tmp. .TP .B index { | default } [ pres,eq,approx,sub,none ] Specify the indexes to maintain for the given attribute. If only an is given, all possible indexes are maintained. .TP .B mode Specify the file protection mode that newly created database index files should have. The default is 0600. .SH SHELL BACKEND-SPECIFIC OPTIONS Options in this category only apply to the SHELL backend database. That is, they must follow a "database shell" line and come before any subsequent "database" lines. The Shell backend executes external programs to implement operations, and is designed to make it easy to tie an existing database to the .B slapd front-end. .TP .B bind .TP .B unbind .TP .B search .TP .B compare .TP .B modify .TP .B modrdn .TP .B add .TP .B delete .TP .B abandon These options specify the pathname of the command to execute in response to the given LDAP operation. The command given should understand and follow the input/output conventions described in Appendix B of "The SLAPD and SLURPD Administrator's Guide." .LP Note that you need only supply configuration lines for those commands you want the backend to handle. Operations for which a command is not supplied will be refused with an "unwilling to perform" error. .SH PASSWORD BACKEND-SPECIFIC OPTIONS Options in this category only apply to the PASSWD backend database. That is, they must follow a "database passwd" line and come before any subsequent "database" lines. The PASSWD database serves up the user account information listed in the system .BR passwd (5) file. .TP .B file Specifies an alternate passwd file to use. The default is .B /etc/passwd. .SH EXAMPLE "The SLAPD and SLURPD Administrator's Guide" contains an annotated example of a configuration file. .SH FILES ETCDIR/slapd.conf .SH SEE ALSO .BR ldap (3), .BR slapd.replog (5), .BR locale (5), .BR passwd (5), .BR slapd (8), .BR slurpd (8), .LP "The SLAPD and SLURPD Administrator's Guide" .SH ACKNOWLEDGEMENTS .B OpenLDAP is developed and maintained by The OpenLDAP Project (http://www.openldap.org/). .B OpenLDAP is derived from University of Michigan LDAP 3.3 Release.
